Single Idea 15050

[filed under theme 7. Existence / C. Structure of Existence / 2. Reduction ]

Full Idea

One line of reduction is logical analysis. To say one sentence reduces to another is to say that they express the same proposition (or fact), but the grammatical form of the second is closer to the logical form than the grammatical form of the first.

Gist of Idea

Reduction might be producing a sentence which gets closer to the logical form

Source

Kit Fine (The Question of Realism [2001], 3)

Book Ref

-: 'Philosophers' Imprint' [-], p.8

A Reaction

Fine objects that S-and-T reduces to S and T, which is two propositions. He also objects that this approach misses the de re ingredient in reduction (that it is about the things themselves, not the sentences). It also overemphasises logical form.

The 17 ideas from 'The Question of Realism'

15007 If you make 'grounding' fundamental, you have to mention some non-fundamental notions [Sider on Fine,K]
15047 What is real can only be settled in terms of 'ground' [Fine,K]
15046 Reality is a primitive metaphysical concept, which cannot be understood in other terms [Fine,K]
15048 In metaphysics, reality is regarded as either 'factual', or as 'fundamental' [Fine,K]
15006 Something is grounded when it holds, and is explained, and necessitated by something else [Fine,K, by Sider]
15050 Reduction might be producing a sentence which gets closer to the logical form [Fine,K]
15051 Reduction might be semantic, where a reduced sentence is understood through its reduction [Fine,K]
15052 Reduction is modal, if the reductions necessarily entail the truth of the target sentence [Fine,K]
15054 'Quietist' says abandon metaphysics because answers are unattainable (as in Kant's noumenon) [Fine,K]
15053 If metaphysics can't be settled, it hardly matters whether it makes sense [Fine,K]
15055 Grounding relations are best expressed as relations between sentences [Fine,K]
15056 The notion of reduction (unlike that of 'ground') implies the unreality of what is reduced [Fine,K]
15057 Ultimate explanations are in 'grounds', which account for other truths, which hold in virtue of the grounding [Fine,K]
15058 A proposition ingredient is 'essential' if changing it would change the truth-value [Fine,K]
15059 Grounding is an explanation of truth, and needs all the virtues of good explanations [Fine,K]
15061 Although colour depends on us, we can describe the world that way if it picks out fundamentals [Fine,K]
15060 Why should what is explanatorily basic be therefore more real? [Fine,K]
