The American Heritage Dictionary, Fourth Edition, defines nominalism as "the doctrine holding that abstract concepts, general terms, or universals have no independent existence but exist only as names. The American Heritage Dictionary of the English Language ( AHD) is an American Dictionary of the English language published by In Metaphysics, a universal is what particular things have in common namely characteristics or qualities " Nominalism has also been defined as a philosophical position that various objects labeled by the same term have nothing in common but their name. [1] Nominalism is the view that only actual physical particulars are real, and that universals exist only post res, that is, subsequent to particular things. [2]

The term "nominalism" and its contrary, realism, emerged out of debates in medieval philosophy. Contemporary philosophical realism is the belief in a Reality that is completely Ontologically independent of our conceptual schemes linguistic practices beliefs Contemporary philosophical realism is the belief in a Reality that is completely Ontologically independent of our conceptual schemes linguistic practices beliefs Medieval realism, which is quite distinct from realism in the modern sense, holds that when humans employ descriptive terms such as "green" or "soft," they are unwittingly referring to Forms, abstract objects whose existence is wholly independent of the physical world. Plato 's Theory of Forms asserts that Forms (or Ideas) and not the material world of change known to us through sensation, possess Medieval realism is ultimately grounded in the metaphysical doctrines of Plato.

The problem of universals

Nominalism arose in reaction to the problem of universals. The problem of universals is an ancient problem in Metaphysics about whether universals exist Specifically, accounting for the fact that some things are of the same type. For example, Fluffy and Kitzler are both cats, or, the fact that certain properties are repeatable, such as: the grass, the shirt, and Kermit the Frog are green. WikipediaManual of Style (spelling, articles should conform to one overall spelling style of English typically the one most linked to the article topic (if it is geographic A shirt is a cloth garment for the upper body Originally an item of underwear worn exclusively by men it has become in American English a catch-all term for Kermit the Frog is a Muppet, one of Puppeteer Jim Henson 's most famous and beloved creations first introduced in 1955 One wants to know in virtue of what are Fluffy and Kitzler both cats, and what makes the grass, the shirt, and Kermit green.

The realist answer is that all the green things are green in virtue of the existence of a universal; a single abstract thing, in this case, that is a part of all the green things. Contemporary philosophical realism is the belief in a Reality that is completely Ontologically independent of our conceptual schemes linguistic practices beliefs In common usage existence is the world of which we are aware through our senses but in Philosophy the word has a more specialized meaning and is often contrasted with --> Abstraction is the process or result of generalization by reducing the information With respect to the colour of the grass, the shirt and Kermit, one of their parts is identical. In this respect, the three parts are literally one. Greenness is repeatable because there is one thing that manifests itself wherever there are green things. Exemplification is a mode of symbolization characterized by the relation between a sample and what it refers to

Nominalism denies the existence of universals. The motivation for this flows from several concerns, the first one being where they might exist. Plato famously held that there is a realm of abstract forms or universals apart from the physical world (see theory of the forms). Biography Early life Birth and family Plato was born in Athens Greece Plato 's Theory of Forms asserts that Forms (or Ideas) and not the material world of change known to us through sensation, possess Particular physical objects merely exemplify or instantiate the universal. But this raises the question: Where is this universal realm? One possibility is that it is outside of space and time. However, naturalists assert that nothing is outside of space and time. This article covers metaphysical naturalism as a worldview Naturalism (philosophy discusses methodological naturalism Some Neoplatonists, such as the pagan philosopher Plotinus and the Christian philosopher Augustine, imply (anticipating conceptualism) that universals are contained within the mind of God. Neoplatonism (also Neo-Platonism) is the modern term for a school of religious and mystical Philosophy that took shape in the 3rd century AD founded by Plotinus ( Greek:) (ca AD 204–270 was a major philosopher of the ancient world who is widely considered the founder of Neoplatonism (along with his Conceptualism is a Doctrine in Philosophy intermediate between Nominalism and realism that says universals exist only within the To complicate things, what is the nature of the instantiation or exemplification relation?

Conceptualists hold a position intermediate between nominalism and realism, saying that universals exist only within the mind and have no external or substantial reality. Exemplification is a mode of symbolization characterized by the relation between a sample and what it refers to Charles Sanders Peirce (pronounced purse) (September 10 1839 &ndash April 19 1914 was an American Logician mathematician, philosopher Conceptualism is a Doctrine in Philosophy intermediate between Nominalism and realism that says universals exist only within the Contemporary philosophical realism is the belief in a Reality that is completely Ontologically independent of our conceptual schemes linguistic practices beliefs MIND ( Moving In New Directions) (est 1975 is an alternative education high school in Montreal, Quebec, Canada.

Moderate realists hold that there is no realm in which universals exist, but rather universals are located in space and time wherever they are manifest. Moderate realism as a position in the debate on the Metaphysics of universals holds that there is no realm in which universals exist (against Platonism, Now, recall that a universal, like greenness, is supposed to be a single thing. Nominalists consider it unusual that there could be a single thing that exists in multiple places simultaneously. The realist maintains that all the instances of greenness are held together by the exemplification relation, but this relation cannot be explained.

Philosophers who delve deeply into the workings of the human brain, such as Daniel Dennett, reject the idea that there is some "greenness" in the real world, only circumstances that cause the brain to react with the judgment "green. Daniel Clement Dennett (born March 28 1942 in Boston, Massachusetts) is a prominent American philosopher whose research "

Finally, many philosophers prefer simpler ontologies populated with only the bare minimum of types of entities, or as W. V. Quine said "They have a taste for 'desert landscapes. In Philosophy, ontology (from the Greek, genitive: of being (part Willard Van Orman Quine (June 25 1908 Akron, Ohio &ndash December 25 2000 (known to intimates as "Van" '" They attempt to express everything that they want to explain without using universals such as "catness" or "chairness. "

Varieties of nominalism

There are various forms of nominalism ranging from extreme to almost-realist. One extreme is "predicate" nominalism. Fluffy and Kitzler are both cats simply because the predicate 'cat' applies to both of them. However, the realist will object as to what the predicate applies.

Resemblance nominalists believe that 'cat' applies to both cats because Fluffy and Kitzler resemble an exemplar cat closely enough to be classed together with it as members of its kind, or that they differ from each other (and other cats) quite less than they differ from other things, and this warrants classing them together. "Exemplars" directs here For the superpowered comic book team see Exemplars (comics. In Philosophy a natural kind is a grouping of things which is a natural grouping not an artificial one Some resemblance nominalists will concede that the resemblance relation is itself a universal, but is the only universal necessary. This betrays the spirit of nominalism. Others argue that each resemblance relation is a particular, and is a resemblance relation simply in virtue of its resemblance to other resemblance relations. This generates an infinite regress, but many agree that it is not vicious. A virtuous circle or a vicious circle is a complex of events that reinforces itself through a Feedback loop toward greater instability

Another form of resemblance nominalism attempts to build upon a theory of tropes. The term " Trope " is both a term which denotes figurative and metaphorical language and one which has been used in various technical senses A trope is a particular instance of a property, like the specific greenness of a shirt. One might argue that there is a primitive, objective resemblance relation that holds among like tropes. "n objective account is one which attempts to capture the nature of the object studied in a way that does not depend on any features of the particular subject who studies it Another route is to argue that all apparent tropes are constructed out of more primitive tropes and that the most primitive tropes are the entities of complete physics. Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. Primitive trope resemblance may thus be accounted for in terms of causal indiscernibility. Two tropes are exactly resembling if substituting one for the other would make no difference to the events in which they are taking part. Varying degrees of resemblance at the macro level can be explained by varying degrees of resemblance at the micro level, and micro-level resemblance is explained in terms of something no less robustly physical than causal power. David Malet Armstrong, perhaps the most prominent contemporary realist, argues that such a trope-based variant of nominalism has promise, but holds that it is unable to account for the laws of nature in the way his theory of universals can. David Malet Armstrong (born July 8, 1926) often D M Armstrong, is an Australian Philosopher.

Ian Hacking has also argued that much of what is called social constructionism of science in contemporary times is actually motivated by an unstated nominalist metaphysical view. Ian Hacking, CC, PhD, FRSC, FBA (born February 18, 1936 in Vancouver) is a Canadian university Social constructionism and social constructivism are sociological and psychological theories of Knowledge that consider how social phenomena develop in For this reason, he claims, scientists and constructionists tend to "shout past each other. "

Strong proponents of this school of thought include John Locke and George Berkeley. John Locke (29 August 1632 – 28 October 1704 was an English Philosopher. George Berkeley (ˈbɑrkli (12 March 1685 14 January 1753 also known as Bishop Berkeley, was a Philosopher.

Analytic philosophy and mathematics

The notion that philosophy, especially ontology and the philosophy of mathematics should abstain from set theory owes much to the writings of Nelson Goodman (see especially Goodman 1977), who argued that concrete and abstract entities having no parts, called individuals exist. In Philosophy, ontology (from the Greek, genitive: of being (part The philosophy of mathematics is the branch of Philosophy that studies the philosophical assumptions foundations and implications of Mathematics. Henry Nelson Goodman ( 7 August 1906, Somerville Massachusetts &ndash 25 November 1998, Needham Massachusetts) Collections of individuals likewise exist, but two collections having the same individuals are the same collection.

The principle of extensionality in set theory assures us that any matching pair of curly braces enclosing one or more instances of the same individuals denote the same set. In Logic, extensionality refers to principles that judge objects to be equal if they have the same external properties Hence {a,b}, {b,a}, {a,b,a,b} are all same set. For Goodman and other nominalists of his ilk, {a,b} is also identical to {a,{b}}, {b,{a,b}}, and any combination of matching curly braces and one or more instances of a and b, as long as a and b are names of individuals and not of collections of individuals. Goodman, Richard Milton Martin, and Willard Quine all advocated reasoning about collectivities by means of a theory of virtual sets (see especially Quine 1969), one making possible all elementary operations on sets except that the universe of a quantified variable cannot contain any virtual sets. Richard Milton Martin (1916 Cleveland Ohio &ndash 22 November, 1985, Milton Massachusetts) was an American Logician and Willard Van Orman Quine (June 25 1908 Akron, Ohio &ndash December 25 2000 (known to intimates as "Van" The Universe is defined as everything that Physically Exists: the entirety of Space and Time, all forms of Matter, Energy

In the foundation of mathematics, nominalism has come to mean doing mathematics without assuming that sets in the mathematical sense exist. Foundations of mathematics is a term sometimes used for certain fields of Mathematics, such as Mathematical logic, Axiomatic set theory, Proof theory In practice, this means that quantified variables may range over universes of numbers, points, primitive ordered pairs, and other abstract ontological primitives, but not over sets whose members are such individuals. Quantification has two distinct meanings In Mathematics and Empirical science, it refers to human acts known as Counting and Measuring The Universe is defined as everything that Physically Exists: the entirety of Space and Time, all forms of Matter, Energy A number is an Abstract object, tokens of which are Symbols used in Counting and measuring. In Mathematics, an ordered pair is a collection of two distinguishable objects one of which is identified as the first coordinate (or the first entry To date, only a small fraction of the corpus of modern mathematics can be rederived in a nominalistic fashion. On mathematical nominalism, see Burgess and Rosen (1997).
