Which of the following is a similarity between the deontological theory and moral relativism?

Deontological

Deontological (or "duty-based") Ethics

  1. The chief characteristic of deontological theories is: (moral) right (one's duty, how one should act) is defined independently of (moral) good. Deontological theories necessarily generate "categorical imperatives" (that is, duties independent of any theory of good). Here, the emphasis on acts rather than on outcomes, as in utilitarianism.
  2. Chief problem for deontological theory: defining right without appeal to good. Examples of how this problem might be solved:
    1. Right is what God commands. (Divine Command Theory)
    2. Right is what one's society commands. (Moral Relativism)
  3. Deontological theories are not necessarily:
    1. rule-based (God might, for example, issue commands case by case);
    2. universalist (one society may command what another society forbids); or
    3. absolutist (God or society might, for example, lay down general rules allowing exceptions).
  4. What's distinctive about Kant's deontology? Kant claims to derive morality from reason - without appeal to any theory of the good. Morality limits what can properly be done rather than commanding conduct. Morality is a "side constraint" on conduct. (Compare utilitarianism's "demandingness".)
  5. Kant's method offers at least three ways to test an act to see whether it is morally permissible (all—supposedly—equivalent):
    1. Universalizability: act only on those maxims one can will to be universal laws.
    2. Human dignity: act only on those maxims consistent with treating each person as an end, not merely as a means.
    3. Moral legislation: act only on those maxims that all rational persons could adopt as universal rules governing all.
  6. Recent deontologists:
    • Marcus Singer, Generalization in Ethics (1961)
    • Alan Gewirth, Reason and Morality (1978). [out of favor in 1980s and 1990s]

Kantian Method

  1. Identify your act (what you are actually proposing to do), for example, tell someone something you believe to be false.
  2. Identify the end you have in view (your motive, what is actually moving you to do the act in question), for example, getting something without paying for it.
  3. Consider whether (assuming the world otherwise remains as you believe it to be) you could still achieve that end in the way you propose:
    1. if everyone were permitted to act the same whenever they had the same end in view (universalizability test);
    2. if everyone knew you were permitted to act as you propose (disclosure or pre-publicity test, derived from acknowledging the dignity of others, that is, their status as agents with ends of their own); or
    3. if your doing so required every rational person to approve a general rule permitting actions of that kind (moral legislation test).
  4. Reject the act if you find it would fail any of the three tests above. (You may do any act passing all three tests.)

Introduction

Outside the university campus, people are wondering what they ought to do, but inside academic moral philosophy the question generally is: which theory about what to do is superior?

A moral theory consists of more or less connected claims arranged to determine what a morally good or right action or stance is, and what it is that makes it either right or good. It thereby conveys, more or less implicitly, a set of assumptions as to what morality is; that view in turn specifies the type of norms or rules to be found and how they can be grounded. The many variations on virtue ethics, deontological ethics, contractualism, and consequentialism, present us with interesting proposals. Moral theories, understood this way, are generally supposed to be mutually exclusive: their multitude and diversity raises the question whether one moral theory should be accepted as the only right or true one.

The aim of this article is to examine some of the functions and characteristics of classic moral theories from a moral metatheoretical point of view, and to consider how far seeing moral theories as analogous to grammars clarifies what is generally assumed to be the rivalry between them. How can we approach the question of what makes a moral theory good or right? What are the specific strengths of different moral theories and how are we to assess their aims and scopes? Can we seek out specific spheres of life that invite the deployment of one kind of moral theory rather than another? I will argue that different moral theories are neither simply competing nor simply complementary; the orientation of each such theory is matched with, and to be justified by, the range of problems it helps to solve. But while the functionality of a theory plays an important role, it is not the whole story; making room for the moral viewpoints and theories of the future means taking on the challenge of settling criteria for the success of a moral theory.

I will proceed as follows. First, I will further explicate the point of departure of our investigation: here, we will be engaged not in moral theory, but in moral metatheory. Then I will briefly discuss an analogy between moral theories and maps, and argue that we will do better to think of moral theories as analogous to languages. Third, I will talk through some of the general features of moral theories, as well as some of the distinguishing features of specific positions. Finally, I will speak to the question of how we should understand the relations in which moral theories stand to each other, and how we might choose between them.

Moral Metatheory

“So, now just tell me: after all that, which of these is the right one?” It frequently happens that students of philosophy start a class on moral theory with the expectation that they will ultimately learn which moral principles are the right ones and how to assure that their moral decisions are correct. In my view, and I’m probably not alone, the challenge is to reorient those expectations: a teacher aims to present and discuss a number of different theories, and take up their fundamental orientations, their geneses, and their strengths and difficulties. At that point, we are leaving the field of theorizing about morality, to enter into the area of theorizing about moral theories. To think about the merits, the purposes and the status of moral theories is – borrowing a locution from Jason Brennan – to engage in moral metatheory (Brennan 2007).

Philosophizing about morality is a different endeavor than philosophizing about moral theory. If we want to take moral theories as objects of philosophical investigation, as we aim to do here, we have to take a step back: “Generally, moral metatheory is not about the semantics, ontology or epistemology of moral judgments and terms. Rather, it concerns the semantics, ontology, epistemology, and methods of moral theories themselves.” (Brennan 2007: 28) If we mean to examine different moral theories, we have to address questions like: What is the aim of a moral theory? To which (kind of) questions is it an answer? What makes a moral theory good, helpful, adequate, wrong, or better than another?

Generally speaking, moral theories – as the term is used in this paper – answer the question of how to behave in a morally good or right way. They are theories about morality insofar they are systematizations and theoretical representations of a substantial view of morality: within a moral theory, the claims are anchored in consistent assumptions about what is morally relevant, how we find that out, and what morality consists in. They are normative in the sense that they make claims as to what makes an action, a choice or a stance morally valuable.Footnote 1

Thereby, a moral theory takes a stand on what moral norms are: are they human inventions, or a moral law that exists outside of space and time, or rather the outcome of an agreement? It invokes metaethical and anthropological presuppositions, which are expressed in its choice of ethical concepts. That is why, with a view to certain subsidiary aspects of morality, we can assign moral theories to different groups, depending on how a specific moral theory answers questions such as: what concepts are morally especially relevant? – duty or virtue, for example – or the question of what metaphysical assumptions have to be taken on board – are there moral properties or moral facts? – or what makes an action morally right or good. Thus, we assign it to one of the familiar groups of moral theory, that is, consequentialism, deontological ethics, virtue ethics or contractualism.Footnote 2

Accordingly, the term “moral theory” will be used in the following for a systematic compilation of claims about morality that unites statements and explanations of what is a morally right or good action or stance, why it is and how we produce or adopt it.

Now, if moral theories generally claim to render an account of morality, how can we evaluate moral theories and decide which of them are good, right or better?Footnote 3

Thinking about Moral Theories via Analogies

When we ask what to expect from a moral theory and what relations they stand in to each other, it will help to have the right analogy. We will try out two analogies: one between theories and maps, and one between theories and languages.

Moral Theories as Maps

David Schmidtz proposes that we think of moral theories as analogous to maps: a theory is a map insofar as it gives us a representation of the object it depicts. (Schmidtz 2007: 433) Such an analogy is helpful up to a certain point; it helps to clarify what we can expect from moral theories. They are neither truths nor realities, but (at best) helpful representations of a certain kind of reality, built to help us orient ourselves in our world. The analogy does justice to the fact that no theory can portray the reality as it is. And it does justice to the fact that every moral itinerary has to be endorsed by the agent in order to give guidance.

But there are at least two difficulties we encounter if we think about moral theories analogously to maps: firstly, moral theories differ from maps insofar as they have the moral destination already built in; and second, they are not only alternate maps of a given terrain, but rather, owing to their fundamentally different understandings of morality, present different versions of the terrain.

At first glance it might seem that they represent one and the same area, namely morality – but their different understandings of the term complicate that assumption. These complications would not be so important if the moral maps all came to the same conclusion. In On What Matters, Derek Parfit argues that consequentialism, deontological ethics and contractualism can be brought together into what he calls the Triple Theory, and have to be understood as different routes to the same destination. He writes that it “has been widely believed that there are … deep disagreements between Kantians, Contractualists, and Consequentialists. That, I have argued, is not true. These people are climbing the same mountain on different sides” (Parfit 2011: 419). Such a position could be illustrated by three different maps representing the same area, giving different possible ways to one destination: the mountain peak. If you ask Google Maps for directions to one and the same mountain peak, once for bicycles, another time for pedestrians, and a third for cars, you will get different route descriptions, depending on what is permitted to each. A bicycle can take some one-way streets the driver of a car is not allowed to, but not, for example, the freeway. But given the very different meanings and functions the disparate theories assign to morality, it seems to me that we should accommodate not only different routes, but also different destinations.

Imagine you are entering an elevator in your administration building to get to your office. Just before the elevator door closes, someone slips in, looks around and says “Where do I have to go?” In order to be helpful, you have to ask him what his destination is, and only then give him the appropriate instructions. However, if the representative of a moral theory is asked where to go, she answers very differently from the helpful occupant of that elevator, by giving both an itinerary and the destination: “What we all seek is Eudaimonia. To achieve it, you have to find the mean between excesses and extremes; just follow the wise person”. Alternatively, “if you are exercising your capacity to reason practically, you will necessarily recognize that the most important feature you have to take into account and prioritize is autonomy (or: the best outcome for all concerned). In order to do that, you have to execute the CI-test (or: make choices so as to maximize the balance of pleasure over pain).”

The different destinations are built into the different understandings of morality, and are expressed in the different ethical concepts moral theories prioritize. While maps are representations of a terrain, moral theories are depictions of two things at once: they represent fundamentally different terrainsFootnote 4, by providing a representation of how the moral world looks, and they give us abstract guidelines, with justifications for those guidelines, which are supposed to escort us through that world.

These differences between maps and moral theories are important enough to tell against the use of this analogy, and to speak for another analogy, namely, thinking about moral theories as like languages.

Moral Theories as Languages

We expect moral theories to tell us (inter alia) what is right or good. That is something that we also want from a language textbook – not concerning the morally right or good, of course, but concerning the linguistically correct. Up to a certain point, to endorse a specific moral theory is like speaking a particular language.

A protagonist in Muriel Barbery’s novel The Elegance of the Hedgehog explains what grammar is for in the following way:

“Personally, I think that grammar is a way to attain beauty. When you speak, or read, or write, you can tell if you’ve said or read or written a fine sentence. You can recognize a well-turned phrase or an elegant style. But when you apply the rules of grammar skillfully, you ascend to another level of the beauty of language. When you use grammar you peel back the layers, to see how it is all put together, see it quite naked, in a way. And that’s where it becomes wonderful, because you say to yourself, ‘Look how well-made this is, how well-constructed it is! How solid and ingenious, rich and subtle!’ … I find there is nothing more beautiful, for example, than the very basic components of language, nouns and verbs.” (Barbery 2008)

In the analogy as developed here, the grammar she talks about corresponds to the ethical concepts we find at the core of our moral theories. To study moral theory may lead one to appreciate another instance of beauty: one can be thrilled and impressed by the eloquence and comprehensive thinking of moral philosophers, as when we are inspired by the Kantian celebration of the human capacity to react not only to needs, natural necessities, and heteronomy, but to think in laws. Some readers will react with consternation to his moral thinking; others may therewith be reconciled with humanity. In any case, when we look at the widely held, more or less “solid and ingenious, rich and subtle” moral theories, we can learn something about the views of morality they are expressions of, and reflect on their respective scopes, functions, and strengths. Just as it helps to compare different languages, to learn more about both one’s native language and others, it helps to examine different moral theories, seeing them as the systematization of different understandings of morality.

Similitudes on different levels invite us to explore the reach and potency of an analogy between moral theories and languages. Accordingly, it is not surprising that various attempts of this kind have already been made.Footnote 5 The point I am after is that moral theories have basic concepts and structures that express their respective views regarding morality (as grammars are underlying structures of languages and allow for the expression of a certain worldview), and that these structures and basic concepts necessarily affect and shape how we think about moral relevance and goodness.Footnote 6 In particular, we will examine three enlightening parallels: moral theories and languages have room for normativity, they change over time, and they are expressions of a certain view.

Some Thoughts on Normativity

In everyday life, we know how to speak and we are able to differentiate grammatically incorrect from correct sentences, even if often we cannot state the underlying rule and cannot explain why the utterance is correct or incorrect. Matters might be seen as similar in the case of morality: We know that you do not need to work in moral philosophy and to argue about moral theory in order to develop a view as to what is morally right or wrong.

Textbooks for languages and grammars as well as moral theories provide systematizations of normative statements: they tell you what is right or the best, and why. But the role of normativity seems to be completely different when it comes to languages and morals, because – at least at first glance – the normative force of their rules and principles are drawn from very different sources. Due to the role of normativity, in both cases we lack the tools available in other fields for corroborating theories at our disposal. Like language textbooks, moral theories do not provide predictions on the basis of previous observations; but unlike these textbooks, there is no field investigation that would be decisive for the normative force of their guidelines. Linguists indeed take an inductive approach, but what they draw on and transform into a concept are not (only and primarily) predictions about how people will speak, but which use of the language is correct. Thus they are formulating normative statements, converting a statistical norm to an instruction; whoever wants to speak correctly has to do it this way. Moral theories are even farther away from such an anchor: recourse to statistical data plays no role. We cannot rely on experiments or use special telescopes to verify our assumptions about moral norms or values.Footnote 7 Moral theories express and justify a way the world could be, and a way of doing and being that is normatively conceived – the question of whether we ever observe a morally good or right act has no conclusive force concerning the correctness of a moral theory.Footnote 8

As far as normativity goes, moral theories are even more disconnected from empirical observation than grammars. On the one hand, there is the widely shared assumption that a norm, in order to count as a moral norm, has to be justified and valid independently of contingent circumstances. On the other hand, moral theories specify more or less abstract and general norms to provide orientation and guidance – and to ensure this, in addition to the dissociation from the real world I have just mentioned, there must be a certain connection to it. To give helpful answers, in compliance with questions and problems that arise in the real world, they have to keep up with the times, so to speak.

That there is at once dependence and independence of the worth of moral theories from the current reality can be rendered comprehensible if we differentiate between a theory being effective in an absolute sense (that it gives us what we need to know about being and acting morally, for all time and in all morally relevant situations) and its being effective in specific kinds of situations and circumstances (it gives us what we need to know for specific morally relevant situations). This is not to be confounded with the kind of relativity that is often taken as the counterpart to absoluteness, as if we had to choose between the frying pan (absolutism) and the fire (relativism). We are dealing here with a very particular form of relativity: the connection between moral guidelines and the specific kind of situation for which they are appropriate. The importance of a connection between norms and problems they help to solve can be seen on a variety of levels, if we focus on their change and continued development.

About Changes through Time

Conceptions of moral theories and morality, like languages and grammars, change over time. We are all familiar with the continued development of Utilitarianism, introduced as a systematic account by Bentham and refined by Mill and his heirsFootnote 9, as well as with the evolution of other moral theories. The development of languages and grammars can for example be observed in the emergence of French to Latin: not only words change over time, but also very basic grammatical structures.Footnote 10 There are interesting commonalities and differences that will support the proposal I have just made: we should not determine the goodness of a moral theory by referring it to any absolute standard of rightness, but focus on its connection to specific situations and circumstances and examine its response potential.

Languages change depending on social and personal needs of expression, i.e., for pragmatic reasons. They change when new entities appear that have to be given names; sometimes new terms are created, sometimes terms are borrowed from other languages (as “PC” found its way into German, while French invented the “ordinateur”; maybe one day we will need a new kind of category in between subject and object, together with a new kind of verb, for the behavior of robots). In contrast to the rules of a grammar, moral principles and guidelines are usually supposed to be grounded and justified in an ahistorical way: moral theories and moral philosophers typically purport to have seized the moral once and for all.Footnote 11 We are used to thinking of moral theories as universal and eternal. However, we should think not only of languages but also of moral theories as children of their time,Footnote 12 and examine how and why they undergo change.

There are two main ways for moral theories to change that correspond to two sources of criticism: moral theories can be modified because deficiencies and gaps are revealed either by their application (whether it be in real life or in thought experiments) or on an abstract level, in theoretical debates. Often these two reasons for development and change appear together and are argumentatively combined.Footnote 13

Generally speaking, moral theories change by and by as single aspects are picked out and discussed in theoretical debates. Such revisions yield the variations that together form the familiar groups of moral theories. Larger and more extensive changes occur if a traditional theory is judged fundamentally insufficient; then a moral theory can be built that grounds a new group of theories.

As we need new terms and maybe even new grammatical structure, so we need new moral rules and principles, as the world in which we live changes: for example, the biblical commandments were helpful in earlier times (e.g. levirate marriage); some norms are helpful for the local environment, but need to be reworked when the scope of our activity changes (see for example Hans Jonas’ attempt to develop an Ethics for the Technological Age, 2003); in present times, we need guidelines and orientation for handling hyperspecialization (a problem that was not even imaginable some hundred years ago; cf. Millgram 2015). It is not the rightness of a moral theory that changes over time, but the frequency of possible applications, i.e. the connection between different moral theories and the questions and problems agents actually face.Footnote 14

Theories as Expressions of Specific Views

It has become proverbial that learning a new language is getting to know a new world. As different grammars underlie and adjust languages, each reflecting a specific worldview and cultural heritage, so different moral theories support and express different interpretations of what counts as morally relevant, what as moral value(s) and what as principle(s). We can learn a new language and thereby acquire a new interpretation of the world. And we can learn to see through the lenses of new moral theories and thereby acquire new conceptions of morality, and their accompanying interpretations of given situations. A language enables us to express our perceptions of our surroundings and of the world, but it also sets limits: Every language conveys different associations, and is particularly good at allowing the expression of one thing, context, and connection, rather than another.Footnote 15 In the same way, we have to understand each moral theory as suitable for the expression and structural reinforcement of a specific understanding of what morality is. This is not meant in the same sense as would be the expressivist pronouncement that a moral judgment is the expression of a personal commitment – it is rather a take on what morality is. Thus, one theory highlights autonomy, another pleasure and pain, others equality, and still others stances and virtues. The different aspects that are taken to be morally relevant go hand in hand with the structure and concepts a moral theory provides. The underlying structures of morality, that is, the different ways to understand it, are determinant: Seeing the world through deontological eyes is a different kind of moral understanding than seeing it through contractualist or consequentialist eyes.Footnote 16

I want to suggest that these differences are due, inter alia, to the questions moral theories are supposed to answer. I want to see how to draw characteristics out from some well-known versions of moral theories, to show how a moral view is determined by a specific “diction”. Can we find questions or even spheres of life that suit specific moral theories (or groups of moral theories) better than others? If so: What are the contexts in which a specific theory provides the best expressive possibilities, and offers the best guidance?

Different Moral Theories and Their Respective Strengths

Each in its own way, the extant moral theories tell us what we ought to do and how to find that out. The differences in their answers are due to, among other things, the different personal, social, and philosophical backgrounds against which these theories have been built up and the questions that emerged under those circumstances. It is not by accident that ancient virtue ethics, focused on excellence in one’s character, has flourished in times when people believed they lived in a well-ordered cosmos. It is not by coincidence that Hobbes, Rousseau and other contractualists emphasized equality, in times when the social and political background prepared people to think about equal rights. Kant wrote his Critiques when people still could hope that the use and development of reason would solve the various difficulties humanity faces. And the Utilitarianism of Bentham and Mill goes with an aspiration to concretely and effectively change society as a whole for the better, paying attention to human needs and to real-world conditions. Depending on what exactly is being sought and on how the search is performed,Footnote 17 different implications are built into the questions and the answers. That goes with a thought Wittgenstein noted in his Philosophical Remarks: “I should like to say: for any question there is always a corresponding method of finding. Or you might say, a question denotes a method of searching” (Wittgenstein 1998: 77). According to David Schmidtz, a “context is a question that motivates us to theorize. ‘What are my children due?’ is one context. ‘What are my employees due?’ is another.” (Schmidtz 2007: 448) If we want to know which contexts a specific theory is appropriate for, we have to look at the questions to which they give answers and find spheres in which we can take advantage of their respective particular strengths.

In order to get there, I will take a bird’s-eye view; this means that I won’t do justice to any one theory. Instead I will be briefly pointing out some characteristics of particular variants, in order to move towards an answer to the question of how to find what different moral theories are good for. Some classical, only roughly outlined variants of the extant groups of moral theories will serve to illustrate the following point: In fact, the variants of the different groups of moral theories are supposed to give answers to different questions, and these questions can help us to locate their strengths.

Virtue Ethics

The ancient variant of virtue ethicsFootnote 18 is commonly taken to answer the question of what sort of person we want to be and how we should live. Someone who accepts virtue ethics as one of the major approaches of normative ethics, that is, as a moral theory discussed in the sense here, might state that it “emphasizes the virtues, or moral character, in contrast to the approach that emphasizes duties or rules (deontology) or that emphasizes the consequences of actions (consequentialism)” (Hursthouse/Pettigrove 2016). While other moral theories may, and indeed often do, also speak to the virtues, for virtue-ethical theories, virtues and vices are foundational, and other normative notions can be grounded in them. We should understand those virtues as excellent traits of character.

Aristotle holds that there is a characteristic function humans have, namely the “activity of the soul in accordance with virtue, and if there are several virtues, in accordance with the best and most complete” (Crisp 2000: 1098a). One underlying idea of his theory is the existence of a well-ordered totality in which the human being is embedded. By precise observation and exploration of the human constitution and its position within this arrangement, we can arrive at an impression of the telos of human beings and of how they have to conduct themselves, to be in accord with their nature and the cosmos as a whole. Accordingly, as Odo Marquard observes, the Greek conceptual world and thus also the roots of virtue ethics are elicited in a world shaped by “the teleological, purposive and functional constitution of the world and of course of the human.” (Marquard 2013: 58, my translation).

That means that Aristotelian virtue ethics was outlined in a significantly more orderly world than the one in which we find ourselves today. Can we nonetheless assign to virtue ethics a sphere in which its response potentials can benefit us the most? In a nutshell: Virtues are not insulated attitudes, but pertain to a network of connected preferences, hopes, beliefs, and inclinations. The adoption of virtues leads to a kind of personal order that works to orient and guide a good lifeFootnote 19, and thereby is still of great value at least in the personal and intimate sphere. Within the personal cosmos, virtues we develop and consolidate can play the same orienting role they do for a person living in a well-ordered cosmos; up to a certain point, we can order our life cosmos by developing views of our own, making ourselves into the kind of person who tries to become excellent in some of her activities and relations.

Contractualism

In a broad sense, contractualism can be construed as the view that moral norms derive their normative force from a contract or mutual agreement. Here is how Rousseau formulates the challenge: “Find a form of association that will bring the whole common force to bear on defending and protecting each associate’s person and goods, doing this in such a way that each of them, while uniting himself with all, still obeys only himself and remains as free as before” (Rousseau 1762: VI). At the time, the notion that every individual is equal and counts – that every person takes an active part in determining the content of the laws and that doing so is required for their legitimacy – was a pioneering proposal. Important aspects of contractualism are (among others) the more or less implicit idea of equality, as well as the demand to acknowledge this equality by integrating everyone into the decision-making that determines the joint rules of play. The ideal basis of common rules would be – if we follow Rousseau – that every person is integrated in a way that makes her amenable to the law, and makes her follow it, all the while remaining obedient only to the law she has given to herself.

The difficulties are enormous and the approach continues to be controversial – still, some of these problems do not arise from Rousseau’s conception, but rather from our contemporary conception of democracy. There is a difference between joint decision-making, where everyone puts his own personal needs and desires on the table, the formulation of norms then consisting in the finding of compromises, and a form of decision-making in which everybody puts on the table what he thinks to be the best norms and obligations for the group and the common undertaking as a whole. We live democracy construed in the first of these ways; but that is not a sufficient reason to simply drop from the agenda the Rousseauvian so-called common will. Collective decision-making need not be endorsing the wishes of the party with the strongest lobby or the summing up of preferences; rather it would be most expedient if the functioning of the decision-making community had priority.

Contractualist thinking, understood this way, should be expedient and helpful in spheres that aim at joint action and constellations of collective life that are delimited in scope, which can however be dissolved at will. Here I’m thinking for example of residential communities, or political parties that have a small, limited membership, but also of personal relationships. These common undertakings are small-scale in the sense that everyone has to be able to influence the procedure and the course of the joint project. Interpreted this way, to apply contractualism would mean to engage in group undertakings in which equality of rights and equal access to decision-making are realized.

Deontological Ethics

The idea of a law one gives oneself found uptake in deontological ethics, and in particular in its Kantian version. Here our capacity to reason is the subject of criticism and is, in Kant’s view, proved to be much more important for morality than any individual interest or need could ever be. It is our reasoning that helps us to discover and formulate what “morally to ought to do something” means. In his view, something we ought to do must be something that can be expressed in the form of a law; a law in turn is something that is valid for everyone, independent of personal needs and inclinations. Every personal guiding principle – every maxim – that complies with what is morally right must be consistently thinkable as a law (Kant 1785).Footnote 20

What is the strength of an approach in morality that takes freedom from contradiction and valuing practical reasoning as its central features? Freedom from contradiction goes too far when it bans purely benevolent actions, or prevents one from building one’s own personal cosmos, and so thwarts practical reasoning.Footnote 21 But freedom from contradiction may play a decisive role in the construction and execution of intentions. To intend something is to be differentiated from merely wanting it by the normativity integrated into the concept of intending. In her “Consistency in Action”, Onora O’Neill formulates requirements of rationality that intentions have to meet. For example, “it is a requirement of rationality not merely to intend all necessary and some sufficient means to what is fundamentally intended but also to seek to make such means available when they are not” (O’Neill 2001: 312). Already as children, we learn that intending something comes along with self-regulation and renunciation. To intend something and to take the necessary steps towards accomplishing it are closely connected to our ability to reason practically. We have to acknowledge this ability in order to deploy it.

Whether it is preparing a talk, producing an artwork, or fulfilling any long-term plan, so long as we intend something, we have to target a certain freedom from contradiction in our intentions, and to value our capacity to reason, in order to fulfill two necessary conditions of success. Thus, valuing one’s own and others’ capacity to form intentions that are sufficiently free from contradiction to be successfully pursued marks appropriate areas of application for deontological ethics.

Consequentialism

According to consequentialism, whether an act is morally right depends on its consequences: “an act is right if that act maximizes the good, that is, if and only if the total amount of good for all, minus the total amount of bad for all, is greater than this net amount for any incompatible act available to the agent on that occasion” (Sinnott-Armstrong 2019). Its paradigm, advocated by Bentham, Mill, and Sidgwick, is Utilitarianism, i.e. Hedonistic Consequentialism. Since then, many refinements and specifications of consequentialism have been undertaken; luckily, for present purposes it will suffice to focus on the thought that the rightness of an act depends on its consequences, in order to think about the accompanying two-phase nature of the concept.

What is it that makes consequences good, bad, or worth being realized? Clearly, we need an axiology. But how do we identify which criterion should be decisive for the evaluation of consequences? The answer to this question ultimately depends on anthropological assumptions. Some classic representatives, such as Mill and Sidgwick, clarify this issue by invoking a non-moral good, namely the greatest happiness of the greatest number. The decisive role of assumptions about the way we are and the consequences of what we do for our own lives and those of our fellows is connected to the impression that, if we want to live in a better world than we do, it doesn’t suffice to concentrate on one’s own virtues, or follow the rules of practical reasoning; rather, we have to take concrete decisions leading to actions that have a positive impact on the world we live in.

In order to make the world a better place for (as far as possible) all sentient beings, an agent has to have a view to the real-world possibilities and conditions. One important challenge is to identify good or even the best consequences; another challenge is to discern means to attain these objectives.Footnote 22 Our options and circumstances are in part determined by structural features of domains in which joint action is needed, but equal participation is impossible. The two-phase nature of consequentialism makes it an optimal theory inter alia for those spheres of life in which an antecedently determined definition of the target is available, and a person has to find out by instrumental reasoning what to do to reach that goal. That is why consequentialism is adequate for spheres in which someone has to live up to a prospective responsibility, for instance, if she or he holds political office. From this point of view, consequentialism captures – among other things not mentioned here – the deliberative structure of some role-based reasoning.

To be sure, many other aspects of the several moral theories could be emphasized, and they have been painted with a broad brush. Moreover, some theories may belong to more than one sphere. Nonetheless, I suggest thinking of moral theories as being more or less good if they supply moral guidance in a certain kind of situation, i.e. if they fit a question.

If we assume that every moral theory provides its own tools and concepts with which to describe and evaluate the morally relevant aspects of a decision situation, we have to recognize that, for one thing, each theory comes with a specific view of morality, and that, on the other hand, we cannot draw from it an independent and self-evident criterion to choose between different theories. In Schmidtz’s words: “if opposing players are disputing a rule, we cannot settle the dispute by consulting a player. We need a referee” (Schmidtz 2007: 441). Simple functionality, as we have characterized it so far, cannot be the criterion we seek: what functionality means in this context is concretized in many different ways, and different moral theories will imply different renditions of it. Thus, one outstanding and crucial question is what mode of thinking is to handle overlaps.

How to Choose the Suitable Theory

If you do not take as moral only those problems that are addressed by a given moral theory, you may allow that different contexts and respective questions are best dealt with by different theories – for “[n]o one moral theory adequately addresses the full range of moral problems” (Brennan 2007: 61). In other words, and falling back on the analogy: there is no single language that enables us to express everything equally well, and that should be henceforth spoken by everyone.Footnote 23 It is good to master one language – to speak two or more languages is even better, not least because it extends one’s world view, one’s ability to act and one’s scope of activity.

As long as we find contexts in which a moral theory provides helpful strategies, we should retain it in our toolkit. But what does it mean for a moral theory to give “helpful” recommendations? This is again a normative question. Not everything that helps or works is necessarily good. And as long as we have no criterion for determining what kind of “good” we are looking for, a great deal of work is still to be done. One question is how different moral theories can be combined; another is criteria for appropriate application.

Possibilities of Combination

If every single moral theory has its own strengths and domains of competence, there are at least two different ways to combine them: either we combine the different aspects of each into a single moral theory, thereby endorsing pluralism; or we retain them as distinct and advance an overarching theory assigning the subsidiary moral theories their respective spheres. I recommend an approach to be distinguished both from pluralism, at the level of normative theories, and from attempts at the level of metatheory to combine different theoretical approaches into one unified blend. In contrast to pluralist theories, rather than a normative theory involving several non-reducible values, the recommendation is to deploy several moral theories, without attempting to unify them. Thus, I am rejecting the approach in which these theories would converge on one principle, as in Parfit’s Triple Theory.Footnote 24 This rejection is due to something that becomes apparent in a limitation of the analogy between language and moral theories: there is no common universal structure shared by all moral theories, that could serve as the analog of a common, underlying “universal grammar”, and would allow us to combine their strengths in one joint approach.

In Chomsky’s view, we have to assume that there is an innate universal grammar, which all languages embody and from which particular grammars are derived. If there were something like a “universal grammar of morality”, we could try to transfer Chomsky’s treatment of grammars to morality. But, as we saw, the questions to which different moral theories propose their conflicting answers are not the same. They are sufficiently different to suggest that there is no common basic point of origin or objective, and that we should not hope for a common underlying structure. Even though there are some commonalities (in almost every moral theory we find an expression of the principle of no harm, as we find in every grammar a differentiation between subject and object, for example), the point remains that they serve to highlight different aspects of a situation as morally relevant.

Jason Brennan introduced the concept of “Theory Multiplism”, arguing that we should take the extant moral theories as conceptions that supplement each other. In his view, “some contexts call for simplicity, some for impartiality, and some for rigor” (Brennan 2007: 88), and “the multiplist might employ each [moral theory] for different purposes” (Brennan 2007: 89). We are now in a position to tighten up his concept: if we need orientation for decision-making in groups, we should play the contractualist card; if we need orientation in the intimate sphere, we should play the virtue ethics card, and so forth.Footnote 25 There are situations that one theory can help to resolve and another not.Footnote 26 So, to answer the question of which moral theory is the right one in a given context, the first step to take would be to follow the guidelines concerning different strengths for different contexts. We can extract from the roots of virtue ethics a fruitful conception of virtue: virtues help us to arrange a more or less well-ordered personal cosmos. We can extract from a version of contractualism the idea that equality combined with a joint project presupposes common decision-making that integrates valuing the community and therefore paying attention to the common will. We can learn from Kant to always value the ability to reason practically and to act out of our rational capacities. And we can extract from consequentialism the idea that instrumental reasoning is the kind of practical reasoning we are committed to in cases of fulfilling an antecedently determined goal.

So far, we could be tempted to say: A moral theory is good (or, better than another one) if it ensures orientation in decision-making when needed. But here the analogy to language runs out; it is questionable whether the justification of a moral theory can and should ultimately be purely pragmatic. Perhaps what enables us to get along best in practice is (morally) mistaken?

How to Choose the Suitable Theory

What we have so far is not enough: we need a metatheory, to tell us when to release the clutch, work the gear shift, and bring a different moral theory to bear. We need a criterion that lets us decide when one or another theory should go into effect. How do we decide which one to choose?

To ask for the specific strengths and functions of a moral theory is to ask what it is good for. But that again is a normative question. Exclusion is sometimes called for on the basis of consistency or elegance, sometimes of the scope of application, but often it will actually be due to normative considerations. Thus it may seem we need to think about normative criteria for counting a theory as moral.Footnote 27 But that would only move the initial question to another level and – again – ask what morality is in order to find a systematization of it. Given that we do not have a precise and perfected understanding of morality to start with, I propose to go at it from a different angle: What can we say about criteria for excluding or choosing a theory? The remaining pages will serve to determine three minimal aspects the criteria we are after have to address: It must help us to set respective scopes of application to the moral theories; it must allow for further and new moral theories; and at best it would be self-limiting.Footnote 28

Determining Scopes of Applications

Discussions of classical moral theories reveal not only strengths, but also weaknesses. Time and again the thought reappears that Kantian deontological ethics, with its reputed rigidity and inelasticity, cannot do justice to an environment that demands versatility, and to the moral questions and dilemmas with which we find ourselves confronted; to apply deontological ethics in some contexts thwarts moral action because the procedure is too rigorous – it is important to leave room for exceptions of benevolence, for example. The answers found by virtue ethics can blind us to those rules that should be followed by everyone – sometimes generalizability matters. Consequentialism leads to coarseness when we fail to value autonomy and personhood in contexts in which they are at stake. Just as there “is no difficulty in proving any ethical standard whatever to work ill, if we suppose universal idiocy to be conjoined with it”, as Mill famously wrote in his Utilitarianism, there is no ethical standard that cannot prove unhelpful and indefensible. But finding the limits of a theory doesn’t mean rejecting it. On the contrary, to find their limitations is to ensure their applicability. To see the scope of its application and to find its defeaters helps us use and understand a moral theory appropriately.

Allowing for New Moral Theories

If I’m right, and moral theories answer different questions, the moral theories we have are not exhaustive. New developments will raise new questions, and so press us to find new guidelines for acting – and future moral theories will reconceive morality in fundamentally different ways. It is to be expected not only that new variations on the classical moral theories will arise, but also that fundamentally novel concepts will emerge. Humanity’s upcoming challenges will be different from anything we can picture, and so other kinds of moral theories will be needed. We must make room for further moral theories and for practical reasoning that enables us to find and invent new values. Who knows which moral questions and (approaches to) answers may prove beneficial, in the situations in which humans will find one day themselves, situations we cannot even imagine today? And that again means that we need not only to assess the existing different theories with their strengths, weaknesses and appropriate field(s) of application, but to make room for new moral theories. Openness is mandatory.

Being Self-Limiting

These two complications suggest a first approach which leads us to a necessary condition on choice between moral theories. My tentative final proposal is: self-limitation matters; and freedom is a good example for a relevant and promising candidate.

It has been proposed to assess moral theories on the basis of fit for particular problem-solving domains. If we turn to the question of metatheory, that is to the question of which criteria to invoke to choose between moral theories, the corresponding thought would be to choose the one best suited to that domain, that is, to pick out one rather than another moral theory for a particular application. At this point we want to avoid at least one thing: an infinite regress. We do not want to find various criteria that are, firstly, finite, concrete, and exclusive, and that, secondly, come with a claim to be all-embracing. The challenge of choice on the first level arose because moral theories are generally supposed to be mutually exclusive and all-embracing; if the selection criteria were self-limiting, we would at least prevent this regress. A self-limiting criterion is one that entails constitutive limits, i.e. self-regarding reasons to restraint. Freedom is self-limiting in the sense that, even if there were no value worth restricting our freedom for, for freedom to prevail it has to limit itself: The best reason to limit freedom is the enabling of freedom.

A Preliminary Conclusion

When we have to choose between different moral theories, we should give priority to the theory that preserves openness and freedom. As long as humans are so multifaceted, under development, and undefined, a moral theory must guarantee that we remain free enough to step back and engage in moral reasoning – whatever “morality” may mean.

There are various contexts and situations in which more than one moral theory is equally helpful. If there is a drowning child to be saved easily, you will come to the conclusion that you should rescue it, whichever moral theory you consult. But given the different areas in which we are engaged in our everyday and moral life, and which ask for different foci, we should embrace polyphony and be thankful that we have several moral theories at our disposal.

When we face different demands, depending on which theory we apply, we should look to their strengths and weaknesses, and turn to the option with the most adequate moral assumptions for the specific context, while making sure that we promote and respect the possibility of inventing new ones. It seems advisable to be oriented towards selection criteria that comply with maintaining openness and meet self-limitation – as, for example, freedom does.

In which way are deontological theory and moral relativism similar?

Which of the following is a similarity between the deontological theory and moral relativism? Both theories may lead to actions that are not ethically correct.

Which of the following statements is true of the deontological theory and the utilitarian ethical theory?

Which of the following statements is true of the deontological theory and the utilitarian ethical theory? The deontological theory states that people should adhere to their duties when analyzing an ethical dilemma, while the utilitarian ethical theory is founded on the ability to predict the consequences of an action.

Which of the following is a similarity between act utilitarianism and rule utilitarianism?

Similarities Between Act and Rule Utilitarianism Both determine the moral significance of an action by its outcome. They reflect on the consequences or usefulness of an action to a majority of the people, which is the core element of utilitarianism.

What is the difference between ethical relativism and utilitarianism?

Moral Relativism states that all moral standards are equally valid. Utilitarianism claims that all values and preferences are equally valid, but it claims that only a single moral standard is valid (the Utilitarian standard of utility maximization). Morals and values are different.
