Moral skepticism

Last updated

Moral skepticism (or moral scepticism in British English) is a class of meta-ethical theories all members of which entail that no one has any moral knowledge. Many moral skeptics also make the stronger, modal claim that moral knowledge is impossible. Moral skepticism is particularly opposed to moral realism: the view that there are knowable and objective moral truths.

Some defenders of moral skepticism include Pyrrho, Aenesidemus, Sextus Empiricus, David Hume, J. L. Mackie (1977), Max Stirner, Friedrich Nietzsche, Richard Joyce (2001), Michael Ruse, Joshua Greene, Richard Garner, Walter Sinnott-Armstrong (2006b), and the philosopher James Flynn. Strictly speaking, Gilbert Harman (1975) argues in favor of a kind of moral relativism, not moral skepticism. However, he has influenced some contemporary moral skeptics.

Forms of moral skepticism

Moral skepticism is divided into three subclasses: moral error theory (or moral nihilism), epistemological moral skepticism, and noncognitivism. [1] All three of these theories reach the same conclusions, which are:

(a) we are never justified in believing that moral claims (claims of the form "state of affairs x is (morally) good," "action y is morally obligatory," etc.) are true, and, furthermore,
(b) we never know that any moral claim is true.

However, each method arrives at (a) and (b) by a different route.

Moral error theory holds that we do not know that any moral claim is true because

(i) all moral claims are false,
(ii) we have reason to believe that all moral claims are false, and
(iii) since we are not justified in believing any claim we have reason to deny, we are not justified in believing any moral claims.

Epistemological moral skepticism is a subclass of theory, the members of which include Pyrrhonian moral skepticism and dogmatic moral skepticism. All members of epistemological moral skepticism share two things: first, they acknowledge that we are unjustified in believing any moral claim, and second, they are agnostic on whether (i) is true (i.e. on whether all moral claims are false).

Finally, Noncognitivism holds that we can never know that any moral claim is true because moral claims are incapable of being true or false (they are not truth-apt). Instead, moral claims are imperatives (e.g. "Don't steal babies!"), expressions of emotion (e.g. "stealing babies: Boo!"), or expressions of "pro-attitudes" ("I do not believe that babies should be stolen.")

Moral error theory

Moral error theory is a position characterized by its commitment to two propositions: (i) all moral claims are false and (ii) we have reason to believe that all moral claims are false. The most famous moral error theorist is J. L. Mackie, who defended the metaethical view in Ethics: Inventing Right and Wrong (1977). Mackie has been interpreted as giving two arguments for moral error theory.

The first argument people attribute to Mackie, often called the argument from queerness, [2] holds that moral claims imply motivation internalism (the doctrine that "It is necessary and a priori that any agent who judges that one of his available actions is morally obligatory will have some (defeasible) motivation to perform that action" [3] ). Because motivation internalism is false, however, so too are all moral claims.

The other argument often attributed to Mackie, often called the argument from disagreement, [3] maintains that any moral claim (e.g. "Killing babies is wrong") entails a correspondent "reasons claim" ("one has reason not to kill babies"). Put another way, if "killing babies is wrong" is true then everybody has a reason to not kill babies. This includes the psychopath who takes great pleasure from killing babies, and is utterly miserable when he does not have their blood on his hands. But, surely, (if we assume that he will suffer no reprisals) this psychopath has every reason to kill babies, and no reason not to do so. All moral claims are thus false.

Epistemological moral skepticism

All versions of epistemological moral skepticism hold that we are unjustified in believing any moral proposition. However, in contradistinction to moral error theory, epistemological moral skeptical arguments for this conclusion do not include the premise that "all moral claims are false." For example, Michael Ruse [4] gives what Richard Joyce [3] calls an "evolutionary argument" for the conclusion that we are unjustified in believing any moral proposition. He argues that we have evolved to believe moral propositions because our believing the same enhances our genetic fitness (makes it more likely that we will reproduce successfully). However, our believing these propositions would enhance our fitness even if they were all false (they would make us more cooperative, etc.). Thus, our moral beliefs are unresponsive to evidence; they are analogous to the beliefs of a paranoiac. As a paranoiac is plainly unjustified in believing his conspiracy theories, so too are we unjustified in believing moral propositions. We therefore have reason to jettison our moral beliefs.

Nietzsche's moral skepticism centers on the profound and ongoing lack of consensus among philosophers regarding foundational moral propositions. He highlights the persistent debates on whether the basis of right action is rooted in reasons or consequences, and the diverse, conflicting theories within Western moral philosophy. [5]

Noncognitivism

Criticisms

Criticisms of moral skepticism come primarily from moral realists. The moral realist argues that there is in fact good reason to believe that there are objective moral truths and that we are justified in holding many moral beliefs. One moral realist response to moral error theory holds that it "proves too much"—if moral claims are false because they entail that we have reasons to do certain things regardless of our preferences, then so too are "hypothetical imperatives" (e.g. "if you want to get your hair-cut you ought to go to the barber"). This is because all hypothetical imperatives imply that "we have reason to do that which will enable us to accomplish our ends" and so, like moral claims, they imply that we have reason to do something regardless of our preferences. [6]

If moral claims are false because they have this implication, then so too are hypothetical imperatives. But hypothetical imperatives are true. Thus the argument from the non-instantiation of (what Mackie terms) "objective prescriptivity" for moral error theory fails. Russ Shafer-Landau and Daniel Callcut have each outlined anti-skeptical strategies. Callcut argues that moral skepticism should be scrutinized in introductory ethics classes in order to get across the point that "if all views about morality, including the skeptical ones, face difficulties, then adopting a skeptical position is not an escape from difficulty." [7]

The term was first articulated by British philosopher Michael Dummett in an argument against a form of realism Dummett saw as 'colorless reductionism'.

<span class="mw-page-title-main">Epistemology</span> Branch of philosophy concerning knowledge

Epistemology is the branch of philosophy concerned with knowledge. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in (contemporary) epistemology are generally clustered around four core areas:

  1. The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification
  2. Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony
  3. The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs
  4. Philosophical skepticism, which questions the possibility of knowledge, and related problems, such as whether skepticism poses a threat to our ordinary knowledge claims and whether it is possible to refute skeptical arguments
<span class="mw-page-title-main">Ethics</span> Branch of philosophy concerning right and wrong conduct

Ethics or moral philosophy is a branch of philosophy that "involves systematizing, defending, and recommending concepts of right and wrong behavior". The field of ethics, along with aesthetics, concerns matters of value; these fields comprise the branch of philosophy called axiology.

Internalism and externalism are two opposite ways of integration of explaining various subjects in several areas of philosophy. These include human motivation, knowledge, justification, meaning, and truth. The distinction arises in many areas of debate with similar but distinct meanings. Internal–external distinction is a distinction used in philosophy to divide an ontology into two parts: an internal part concerning observation related to philosophy, and an external part concerning question related to philosophy.

In metaphilosophy and ethics, metaethics is the study of the nature, scope, and meaning of moral judgment. It is one of the three branches of ethics generally studied by philosophers, the others being normative ethics and applied ethics.

Skepticism, also spelled scepticism in British English, is a questioning attitude or doubt toward knowledge claims that are seen as mere belief or dogma. For example, if a person is skeptical about claims made by their government about an ongoing war then the person doubts that these claims are accurate. In such cases, skeptics normally recommend not disbelief but suspension of belief, i.e. maintaining a neutral attitude that neither affirms nor denies the claim. This attitude is often motivated by the impression that the available evidence is insufficient to support the claim. Formally, skepticism is a topic of interest in philosophy, particularly epistemology.

Justification is the property of belief that qualifies it as knowledge rather than mere opinion. Epistemology is the study of reasons that someone holds a rationally admissible belief. Epistemologists are concerned with various epistemic features of belief, which include the ideas of warrant, knowledge, rationality, and probability, among others.

Moral relativism or ethical relativism is used to describe several philosophical positions concerned with the differences in moral judgments across different peoples and cultures. An advocate of such ideas is often referred to as a relativist for short.

Moral realism is the position that ethical sentences express propositions that refer to objective features of the world, some of which may be true to the extent that they report those features accurately. This makes moral realism a non-nihilist form of ethical cognitivism with an ontological orientation, standing in opposition to all forms of moral anti-realism and moral skepticism, including ethical subjectivism, error theory ; and non-cognitivism. Within moral realism, the two main subdivisions are ethical naturalism and ethical non-naturalism.

Philosophical skepticism is a family of philosophical views that question the possibility of knowledge. It differs from other forms of skepticism in that it even rejects very plausible knowledge claims that belong to basic common sense. Philosophical skeptics are often classified into two general categories: Those who deny all possibility of knowledge, and those who advocate for the suspension of judgment due to the inadequacy of evidence. This distinction is modeled after the differences between the Academic skeptics and the Pyrrhonian skeptics in ancient Greek philosophy. In the latter sense, skepticism is understood as a way of life that helps the practitioner achieve inner peace. Some types of philosophical skepticism reject all forms of knowledge while others limit this rejection to certain fields, for example, to knowledge about moral doctrines or about the external world. Some theorists criticize philosophical skepticism based on the claim that it is a self-refuting idea since its proponents seem to claim to know that there is no knowledge. Other objections focus on its implausibility and distance from regular life.

Cognitivism is the meta-ethical view that ethical sentences express propositions and can therefore be true or false, which noncognitivists deny. Cognitivism is so broad a thesis that it encompasses moral realism, ethical subjectivism, and error theory.

Ethical subjectivism is the meta-ethical view which claims that:

  1. Ethical sentences express propositions.
  2. Some such propositions are true.
  3. The truth or falsity of such propositions is ineliminably dependent on the attitudes of people.

Evidentialism is a thesis in epistemology which states that one is justified to believe something if and only if that person has evidence which supports said belief. Evidentialism is, therefore, a thesis about which beliefs are justified and which are not.

Ethical intuitionism is a view or family of views in moral epistemology. It is foundationalism applied to moral knowledge, the thesis that some moral truths can be known non-inferentially. Such an epistemological view is by definition committed to the existence of knowledge of moral truths; therefore, ethical intuitionism implies cognitivism.

Moral nihilism is the meta-ethical view that nothing is morally right or morally wrong and that morality doesn't exist.

Contextualism, also known as epistemic contextualism, is a family of views in philosophy which emphasize the context in which an action, utterance, or expression occurs. Proponents of contextualism argue that, in some important respect, the action, utterance, or expression can only be understood relative to that context. Contextualist views hold that philosophically controversial concepts, such as "meaning P", "knowing that P", "having a reason to A", and possibly even "being true" or "being right" only have meaning relative to a specified context. Other philosophers contend that context-dependence leads to complete relativism.

Pyrrhonism is an Ancient Greek school of philosophical skepticism which rejects dogma and advocates the suspension of judgement over the truth of all beliefs. It was founded by Aenesidemus in the first century BCE, and said to have been inspired by the teachings of Pyrrho and Timon of Phlius in the fourth century BCE. Pyrrhonism is best known today through the surviving works of Sextus Empiricus, writing in the late second century or early third century CE. The publication of Sextus' works in the Renaissance ignited a revival of interest in Skepticism and played a major role in Reformation thought and the development of early modern philosophy.

Moral sense theory is a theory in moral epistemology and meta-ethics concerning the discovery of moral truths. Moral sense theory typically holds that distinctions between morality and immorality are discovered by emotional responses to experience. Some take it to be primarily a view about the nature of moral facts or moral beliefs —this form of the view more often goes by the name "sentimentalism". Others take the view to be primarily about the nature of justifying moral beliefs —this form of the view more often goes by the name "moral sense theory". However, some theorists take the view to be one which claims that both moral facts and how one comes to be justified in believing them are necessarily bound up with human emotions.
