Nominalism¶
In metaphysics, nominalism is the view that universals and abstract objects do not actually exist other than being merely names or labels.
Core Idea¶
Nominalism is treated here as the recurring metaphysics identity summarized by this source-grounded definition: In metaphysics, nominalism is the view that universals and abstract objects do not actually exist other than being merely names or labels. In metaphysics, nominalism is the view that universals and abstract objects do not actually exist other than being merely names or labels. There are two main versions of nominalism. One denies the existence of universals—that which can be instantiated or exemplified by many particular things (e.g., strength, humanity).
Scope of Application¶
-
HistoryAncient Greek philosophy. Our term "universal" is due to the English translation of Aristotle's technical term katholou which he coined specially for the purpose of discussing the problem of universals.
-
Medieval philosophy. This is in accord with the analytical method that has since come to be called Ockham's razor, the principle that the explanation of any phenomenon should make as few assumptions as.
-
Mathematical nominalism. 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.
-
The problem of universals. In some languages the equivalent words for blue and green may be colexified (and furthermore there may not be a straightforward translation either – in Japanese "青", which is usually translated as.
-
Documented setting. In philosophy of law, nominalism finds its application in what is called constitutional nominalism.
Clarity¶
A clear use of Nominalism names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In metaphysics, nominalism is the view that universals and abstract objects do not actually exist other than being merely names or labels.
Manages Complexity¶
Nominalism compresses multiple metaphysics details into a stable diagnostic relation. The source shows both the central mechanism—in modern philosophy, nominalism was revived by Thomas Hobbes and Pierre Gassendi.—and the practical consequence—the realist maintains that all the instances of greenness are held together by the exemplification relation, but that this relation cannot be explained. This compression makes cases comparable while leaving parameters, conventions, exceptions, and evidential quality explicit.
Abstract Reasoning¶
- Type the carrier. Identify the metaphysics entities to which the claim applies.
- State the relation. Use the source-grounded identity: In metaphysics, nominalism is the view that universals and abstract objects do not actually exist other than being merely names or labels.
- Check operation and conditions. In contemporary analytic philosophy, it has been defended by Rudolf Carnap, Nelson Goodman, H.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Nominalism transfers literally when a new case preserves the same carrier type, relation, and recognition test. Our term "universal" is due to the English translation of Aristotle's technical term katholou which he coined specially for the purpose of discussing the problem of universals. This is in accord with the analytical method that has since come to be called Ockham's razor, the principle that the explanation of any phenomenon should make as few assumptions as possible. Beyond the home domain. No canonical parent is asserted for Nominalism.
Neighborhood in Abstraction Space¶
Nominalism sits in a moderately populated region (53rd percentile for distinctiveness): it has near-neighbors but no dense thicket of look-alikes.
