26-545: Paradigmatically, universals are abstract (e.g. humanity), whereas particulars are concrete (e.g. the personhood of Socrates). However, universals are not necessarily abstract and particulars are not necessarily concrete. For example, one might hold that numbers are particular yet abstract objects. Likewise, some philosophers, such as D. M. Armstrong , consider universals to be concrete. Most do not consider classes to be universals, although some prominent philosophers do, such as John Bigelow. The problem of universals

52-480: A broader view, the main positions are generally considered classifiable as: extreme realism , nominalism (sometimes simply named "anti-realism" with regard to universals), moderate realism , and idealism . Extreme Realists posit the existence of independent, abstract universals to account for attribute agreement. Nominalists deny that universals exist, claiming that they are not necessary to explain attribute agreement. Conceptualists posit that universals exist only in

78-408: A circle and natural numbers as universals. Plato's views on universals did, however, vary across several different discussions. In some cases, Plato spoke as if the perfect circle functioned as the form or blueprint for all copies and for the word definition of circle . In other discussions, Plato describes particulars as "participating" in the associated universal. Contemporary realists agree with

104-603: A student at the University of Michigan , Wilfrid Sellars was one of the founding members of the first North-American cooperative house for university students , which was then called " Michigan Socialist House " (and which was later renamed " Michigan Cooperative House "). He also campaigned for the socialist candidate Norman Thomas of the Socialist Party of America . Robert Brandom , his junior colleague at Pittsburgh, named Sellars and Willard Van Orman Quine as

130-479: A sustained engagement with the German tradition of transcendental idealism , most obviously in his book Science and Metaphysics: Kantian Variations . Sellars coined certain now-common idioms in philosophy, such as the "space of reasons". This idiom refers to two things. It: Note: (2) corresponds in part to the distinction Sellars makes between the manifest image and the scientific image. Sellars's most famous work

156-413: A version of functional role semantics that he had previously defended in prior publications. For Sellars, thoughts are analogous to linguistic utterances, and both thoughts and linguistic utterances gain their content through token thoughts or utterances standing in certain relations with other thoughts, stimuli, and responses. The son of a socialist, Sellars was involved in left-wing politics. As

182-565: Is "Empiricism and the Philosophy of Mind" (1956). In it, he criticizes the view that knowledge of what we perceive can be independent of the conceptual processes which result in perception. He named this " The Myth of the Given ," attributing it to sense-data theories of knowledge. The work targets several theories at once, especially C. I. Lewis ' Kantian pragmatism and Rudolf Carnap 's positivism. He draws out "The Myth of Jones," to defend

208-518: Is an ancient problem in metaphysics on the existence of universals. The problem arises from attempts to account for the phenomenon of similarity or attribute agreement among things. For example, grass and Granny Smith apples are similar or agree in attribute, namely in having the attribute of greenness. The issue is how to account for this sort of agreement in attribute among things. There are many philosophical positions regarding universals. Taking " beauty " as an example, four positions are: Taking

234-565: The University of Iowa (1938–1946), the University of Minnesota (1947–1958), Yale University (1958–1963), and from 1963 until his death, at the University of Pittsburgh . He served as president of the Metaphysical Society of America in 1977. He was a founder of the journal Philosophical Studies . Sellars is well known as a critic of foundationalist epistemology —the " Myth of the Given " as he called it. However, his philosophical works are more generally directed toward

260-420: The mind , or when conceptualized, denying the independent existence of universals, but accepting they have a fundamentum in re . Complications which arise include the implications of language use and the complexity of relating language to ontology . A universal may have instances, known as its particulars . For example, the type dog (or doghood ) is a universal, as are the property red (or redness ) and

286-538: The referents of general terms, such as the abstract , nonphysical, non-mental entities to which words such as "sameness", "circularity", and "beauty" refer. Particulars are the referents of proper names, such as "Phaedo," or of definite descriptions that identify single objects, such as the phrase, "that person over there". Other metaphysical theories may use the terminology of universals to describe physical entities. Plato's examples of what we might today call universals included mathematical and geometrical ideas such as

312-527: The "manifest image" and the "scientific image" of the world. The manifest image includes intentions, thoughts, and appearances. Sellars allows that the manifest image may be refined through 'correlational induction', but he rules out appeal to imperceptible entities. The scientific image describes the world in terms of the theoretical physical sciences. It includes notions such as causality and theories about particles and forces. The two images sometimes complement one another, and sometimes conflict. For example,

338-607: The United States". His father was the Canadian-American philosopher Roy Wood Sellars , a leading American philosophical naturalist in the first half of the twentieth-century. Wilfrid was educated at the University of Michigan (BA, 1933), the University at Buffalo , and Oriel College, Oxford (1934–1937), where he was a Rhodes Scholar , obtaining his highest earned degree, an MA, in 1940. During World War II, he served in military intelligence. He then taught at

364-413: The conceptual behavior of the "space of reasons" with the concept of a subjective sense experience . This was one of his most central goals, which his later work described as Kantian . In his paper "The Language of Theories“ (1961), Sellars introduces the concept of Kantian empiricism . Kantian empiricism features a distinction between (1) claims whose revision requires abandonment or modification of

416-602: The full spectrum of contemporary English-speaking philosophy, from neopragmatism ( Richard Rorty ) to eliminative materialism ( Paul Churchland ) to rationalism ( Laurence BonJour ). Sellars's philosophical heirs also include Ruth Millikan , Daniel Dennett , Héctor-Neri Castañeda , Bruce Aune , Jay Rosenberg , Johanna Seibt , Matthew Burstein , Ray Brassier , Andrew Chrucky , Jeffrey Sicha , Pedro Amaral, Thomas Vinci , Willem A. de Vries , David Rosenthal , Ken Wilber and Michael Williams . Sellars's work has been drawn upon in feminist standpoint theory , for example in

442-447: The manifest image includes practical or moral claims, whereas the scientific image does not. There is conflict, e.g. where science tells us that apparently solid objects are mostly empty space. Sellars favors a synoptic vision, wherein the scientific image takes ultimate precedence in cases of conflict, at least with respect to empirical descriptions and explanations. In "Meaning as Functional Classification" (1974) Sellars elaborated upon

468-498: The medieval philosophers Roscelin of Compiègne and William of Ockham and contemporary philosophers W. V. O. Quine , Wilfred Sellars , D. C. Williams , and Keith Campbell . The ness-ity-hood principle is used mainly by English-speaking philosophers to generate convenient, concise names for universals or properties . According to the Ness-Ity-Hood Principle, a name for any universal may be formed by taking

494-406: The name of the predicate and adding the suffix "ness", "ity", or "hood". For example, the universal that is distinctive of left-handers may be formed by taking the predicate "left-handed" and adding "ness", which yields the name "left-handedness". The principle is most helpful in cases where there is not an established or standard name of the universal in ordinary English usage: What is the name of

520-515: The possibility of a strict behaviorist world-view. The parable explains how thoughts, intelligent action, and even subjective inner experience can be attributed to people within a scientific model. Sellars used a fictional tribe, the "Ryleans," since he wanted to address Gilbert Ryle 's The Concept of Mind . Sellars's idea of "myth", heavily influenced by Ernst Cassirer , is not necessarily negative. He saw it as something that can be useful or otherwise, rather than true or false. He aimed to unite

546-413: The relation betweenness (or being between ). Any particular dog, red thing, or object that is between other things is not a universal, however, but is an instance of a universal. That is, a universal type ( doghood ), property ( redness ), or relation ( betweenness ) inheres in a particular object (a specific dog, red thing, or object between other things). Platonic realism holds universals to be

572-505: The system of concepts in terms of which they are framed (i.e., modification of the fallible set of constitutive principles underlying knowledge, otherwise known as framework-relative a priori truths) and (2) claims revisable on the basis of observations formulated in terms of a system of concepts which remained fixed throughout. In his "Philosophy and the Scientific Image of Man" (1962), Sellars distinguishes between

598-567: The thesis that universals are multiply-exemplifiable entities. Examples include by D. M. Armstrong , Nicholas Wolterstorff, Reinhardt Grossmann, Michael Loux. Nominalists hold that universals are not real mind-independent entities but either merely concepts (sometimes called "conceptualism") or merely names. Nominalists typically argue that properties are abstract particulars (like tropes) rather than universals. JP Moreland distinguishes between "extreme" and "moderate" nominalism. Examples of nominalists include Buddhist logicians and apoha theorists,

624-632: The two most profound and important philosophers of their generation. Sellars's goal of a synoptic philosophy that unites the everyday and scientific views of reality is the foundation and archetype of what is sometimes called the Pittsburgh School , whose members include Brandom, John McDowell , and John Haugeland . Especially Brandom introduced a Hegelian variety of the Pittsburgh School, often called analytic Hegelianism . Other philosophers strongly influenced by Sellars span

650-560: The ultimate goal of reconciling intuitive ways of describing the world (both those of common sense and traditional philosophy) with a thoroughly naturalist, scientific account of reality. He is widely regarded both for great sophistication of argument and for his assimilation of many and diverse subjects in pursuit of a synoptic vision . Sellars was perhaps the first philosopher to synthesize elements of American pragmatism with elements of British and American analytic philosophy and Austrian and German logical positivism . His work also reflects

676-576: The universal distinctive of chairs? "Chair" in English is used not only as a subject (as in "The chair is broken"), but also as a predicate (as in "That is a chair"). So to generate a name for the universal distinctive of chairs, take the predicate "chair" and add "ness", which yields "chairness".
