Single Idea 7618

[filed under theme 8. Modes of Existence / B. Properties / 12. Denial of Properties ]

Full Idea

Some philosophers are so nominalistic that they would deny the existence of such entities as 'properties' altogether; but science itself does not hesitate to talk freely of properties.

Clarification

Nominalist say only particular items exist

Gist of Idea

Very nominalistic philosophers deny properties, though scientists accept them

A Reaction

Maybe scientists aren't very good at ontology? They talk about forces and energy, but don't seem to know what they are. I am inclined to think that we must include properties in the working ontology of humans, but not into strict physics.

11904 Express natural kinds as a posteriori predicate connections, not as singular terms [Putnam, by Mackie,P]
11908 Putnam bases essences on 'same kind', but same kinds may not share properties [Mackie,P on Putnam]
17505 Using proper names properly doesn't involve necessary and sufficient conditions [Putnam]
17506 I now think reference by the tests of experts is a special case of being causally connected [Putnam]

4099 If Twins talking about 'water' and 'XYZ' have different thoughts but identical heads, then thoughts aren't in the head [Putnam, by Crane]
12026 We say ice and steam are different forms of water, but not that they are different forms of H2O [Forbes,G on Putnam]
3208 Does 'water' mean a particular substance that was 'dubbed'? [Putnam, by Rey]
11192 If causes are the essence of diseases, then disease is an example of a relational essence [Putnam, by Williams,NE]
3893 Often reference determines sense, and not (as Frege thought) vice versa [Putnam, by Scruton]
18890 Putnam smuggles essentialism about liquids into his proof that water must be H2O [Salmon,N on Putnam]

11191 The hidden structure of a natural kind determines membership in all possible worlds [Putnam]
9937 I do not believe mathematics either has or needs 'foundations' [Putnam]
9941 Science requires more than consistency of mathematics [Putnam]

9940 Maybe mathematics is empirical in that we could try to change it [Putnam]

6266 We need the correspondence theory of truth to understand language and science [Putnam]
6264 In Tarski's definition, you understand 'true' if you accept the notions of the object language [Putnam]
6265 Tarski has given a correct account of the formal logic of 'true', but there is more to the concept [Putnam]

6282 Theory of meaning presupposes theory of understanding and reference [Putnam]

6279 A private language could work with reference and beliefs, and wouldn't need meaning [Putnam]

18950 Physics is full of non-physical entities, such as space-vectors [Putnam]
18952 '⊃' ('if...then') is used with the definition 'Px ⊃ Qx' is short for '¬(Px & ¬Qx)' [Putnam]

18962 Unfashionably, I think logic has an empirical foundation [Putnam]
18961 We can identify functions with certain sets - or identify sets with certain functions [Putnam]
4716 The correspondence theory is wrong, because there is no one correspondence between reality and fact [Putnam, by O'Grady]
4714 Putnam's epistemic notion of truth replaces the realism of correspondence with ontological relativism [Putnam, by O'Grady]
14214 If we try to cure the abundance of theories with causal links, this is 'just more theory' [Putnam, by Lewis]
4718 If necessity is always relative to a description in a language, then there is only 'de dicto' necessity [Putnam, by O'Grady]
7624 The word 'inconsiderate' nicely shows the blurring of facts and values [Putnam]
7611 Rationality is one part of our conception of human flourishing [Putnam]
7610 A fact is simply what it is rational to accept [Putnam]

14205 The sentence 'A cat is on a mat' remains always true when 'cat' means cherry and 'mat' means tree [Putnam]
14203 Intension is not meaning, as 'cube' and 'square-faced polyhedron' are intensionally the same [Putnam]
14207 If cats equal cherries, model theory allows reinterpretation of the whole language preserving truth [Putnam]

7617 Before Kant, all philosophers had a correspondence theory of truth [Putnam]
7618 Very nominalistic philosophers deny properties, though scientists accept them [Putnam]

2334 Meaning holism tried to show that you can't get fixed meanings built out of observation terms [Putnam]
2335 Understanding a sentence involves background knowledge and can't be done in isolation [Putnam]
2336 Holism seems to make fixed definition more or less impossible [Putnam]

2342 "Water" is a natural kind term, but "H2O" is a description [Putnam]
2344 If we are going to eliminate folk psychology, we must also eliminate folk logic [Putnam]

2349 Realists believe truth is correspondence, independent of humans, is bivalent, and is unique [Putnam]
2351 Aristotle says an object (e.g. a lamp) has identity if its parts stay together when it is moved [Putnam]
2352 The job of the philosopher is to distinguish facts about the world from conventions [Putnam]
2354 "Meaning is use" is not a definition of meaning [Putnam]
