In philosophy, a thick concept (sometimes: thick normative concept, or thick evaluative concept) is a kind of concept that both has a significant degree of descriptive content and is evaluatively loaded. Paradigmatic examples are various virtues and vices such as courage, cruelty, truthfulness and kindness. Courage for example, may be given a rough characterization in descriptive terms as '...opposing danger to promote a valued end'. At the same time, characterizing someone as courageous typically involves expressing an attitude of esteem or a "pro-attitude", or a (prima facie) good-making quality – i.e. an evaluative statement.
Thick concepts thus seem to occupy a 'middle position' between (thin) descriptive concepts and (thin) evaluative concepts. Descriptive concepts such as water , gold , length and mass are commonly believed to pick out features of the world rather than provide reasons for action, whereas evaluative concepts such as right and good are commonly believed to provide reasons for action rather than picking out genuine features of the world.
This 'double feature' of thick concepts has made them the point of debate between moral realists and moral expressivists. Moral realists have argued that the world-guided content and the action-guiding content cannot be usefully separated,[ disputed – discuss ] indicating that competent use of thick concepts constitutes ethical knowledge. [1] Expressivists, favoring an account of moral values as attitudes projected onto the world, wish to maintain a distinction between the (morally neutral) descriptive features of a thick concept and the evaluative attitudes that typically go with them. [2]
Thick concepts seem to combine the descriptive features of natural concepts such as water with an evaluative content similar to the thin evaluative concepts such as good and right. How are we to understand this ‘combination’? Many theorists treat it as a conjunctive: a thick concept should be analyzed as a conjunction of a descriptive part and an evaluative part which, at least in principle, may be separated. [3] A basic feature of this analysis is thus that the descriptive content of a thick concept may be given in absence of the evaluative content. Returning to the example of courage, ‘…is courageous’ could on this account be analyzed as something along the lines of ‘…opposing danger to promote a valued end’ and ‘this is (prima facie) good-making’. [4] The evaluative part, on this view, may thus be characterized as a ‘prescriptive flag’ attached to the concept. [5] It is, on this view, in principle possible to construct a completely descriptive concept – i.e. without evaluative force – that picked out the same features of the world.
This account of thick concepts has been criticized by other theorists, notably of moral realist persuasion. [6] In their view, the only way to understand a thick concept is to understand the descriptive and evaluative aspects as a whole. The idea is that, for a thick concept, the evaluative aspect is profoundly involved in the practice of using it; one cannot understand a thick concept without also understanding its evaluative point. [7] Therefore, descriptive terms cannot completely fill in the ‘along the lines’ of a description such as ‘…opposing danger to promote a valued end’. These descriptions may allow the novice to see the salient features. However a hooking on to the evaluative perspective allows the person to fully understand the 'thick' concept.
Ethics is the philosophical study of moral phenomena. Also called moral philosophy, it investigates normative questions about what people ought to do or which behavior is morally right. Its main branches include normative ethics, applied ethics, and metaethics.
In metaphilosophy and ethics, metaethics is the study of the nature, scope, ground, and meaning of moral judgment, ethical belief, or values. It is one of the three branches of ethics generally studied by philosophers, the others being normative ethics and applied ethics.
Value theory is the systematic study of values. Also called axiology, it examines the nature, sources, and types of values. As a branch of philosophy, it has interdisciplinary applications in fields such as economics, sociology, anthropology, and psychology.
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.
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. Moral realism's two main subdivisions are ethical naturalism and ethical non-naturalism.
John Henry McDowell is a South African philosopher, formerly a fellow of University College, Oxford, and now university professor at the University of Pittsburgh. Although he has written on metaphysics, epistemology, ancient philosophy, nature, and meta-ethics, McDowell's most influential work has been in the philosophy of mind and philosophy of language. McDowell was one of three recipients of the 2010 Andrew W. Mellon Foundation's Distinguished Achievement Award, and is a Fellow of both the American Academy of Arts & Sciences and the British Academy.
Emotivism is a meta-ethical view that claims that ethical sentences do not express propositions but emotional attitudes. Hence, it is colloquially known as the hurrah/boo theory. Influenced by the growth of analytic philosophy and logical positivism in the 20th century, the theory was stated vividly by A. J. Ayer in his 1936 book Language, Truth and Logic, but its development owes more to C. L. Stevenson.
In moral philosophy, deontological ethics or deontology is the normative ethical theory that the morality of an action should be based on whether that action itself is right or wrong under a series of rules and principles, rather than based on the consequences of the action. It is sometimes described as duty-, obligation-, or rule-based ethics. Deontological ethics is commonly contrasted to consequentialism, utilitarianism, virtue ethics, and pragmatic ethics. In this terminology, action is more important than the consequences.
The is–ought problem, as articulated by the Scottish philosopher and historian David Hume, arises when one makes claims about what ought to be that are based solely on statements about what is. Hume found that there seems to be a significant difference between descriptive statements and prescriptive statements, and that it is not obvious how one can coherently transition from descriptive statements to prescriptive ones.
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.
Philippa Ruth Foot was an English philosopher and one of the founders of contemporary virtue ethics. Her work was inspired by Aristotelian ethics. Along with Judith Jarvis Thomson, she is credited with inventing the trolley problem. She was elected a member of the American Philosophical Society.
In meta-ethics, expressivism is a theory about the meaning of moral language. According to expressivism, sentences that employ moral terms – for example, "It is wrong to torture an innocent human being" – are not descriptive or fact-stating; moral terms such as "wrong", "good", or "just" do not refer to real, in-the-world properties. The primary function of moral sentences, according to expressivism, is not to assert any matter of fact but rather to express an evaluative attitude toward an object of evaluation. Because the function of moral language is non-descriptive, moral sentences do not have any truth conditions. Hence, expressivists either do not allow that moral sentences to have truth value, or rely on a notion of truth that does not appeal to any descriptive truth conditions being met for moral sentences.
Cornell realism is a view in meta-ethics, associated with the work of Richard Boyd, Nicholas Sturgeon, and David Brink, who earned his Ph.D. at Cornell University. There is no recognized and official statement of Cornell realism, but several theses are associated with the view.
Metaepistemology is the branch of epistemology and metaphilosophy that studies the underlying assumptions made in debates in epistemology, including those concerning the existence and authority of epistemic facts and reasons, the nature and aim of epistemology, and the methodology of epistemology.
Allan Fletcher Gibbard is the Richard B. Brandt Distinguished University Professor of Philosophy Emeritus at the University of Michigan, Ann Arbor. Gibbard has made major contributions to contemporary ethical theory, in particular metaethics, where he has developed a contemporary version of non-cognitivism. He has also published articles in the philosophy of language, metaphysics, and social choice theory: in social choice, he first proved the result known today as Gibbard-Satterthwaite theorem, which had been previously conjectured by Michael Dummett and Robin Farquharson.
Jonathan Peter Dancy is a British philosopher, who has written on ethics and epistemology. He is currently Professor of Philosophy at University of Texas at Austin and Research Professor at the University of Reading. He taught previously for many years at the University of Keele.
Moral particularism is a theory in normative ethics that runs counter to the idea that moral actions can be determined by applying universal moral principles. It states that there is no set of moral principles that can be applied to every situation, making it an idea appealing to the causal nature of morally challenging situations. Moral judgements are said to be determined by factors of relevance with the consideration of a particular context. A moral particularist, for example, would argue that homicide cannot be judged to be morally wrong until all the morally relevant facts are known. While this stands in stark contrast to other prominent moral theories, such as deontology, consequentialism, and virtue ethics, it finds its way into jurisprudence, with the idea of justifiable homicide, for instance. In this case, the morally relevant facts are based on context rather than principle. Critics would argue that even in this case, the principle still informs morally right action.
Quietism in philosophy sees the role of philosophy as broadly therapeutic or remedial. Quietist philosophers believe that philosophy has no positive thesis to contribute; rather, it defuses confusions in the linguistic and conceptual frameworks of other subjects, including non-quietist philosophy. For quietists, advancing knowledge or settling debates is not the job of philosophy, rather philosophy should liberate the mind by diagnosing confusing concepts.
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.
Brad Hooker is a British-American philosopher who specialises in moral philosophy. He is a professor at the University of Reading and is best known for his work defending rule consequentialism.
