| Identity theory (philosophy of the mind): the thesis that mind states are nothing but states of the brain. Types of identity theory are the weaker assumption of a type-type identity and the stronger assumption of a token-token identity._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

W.V.O. Quine on Identity Theory - Dictionary of Arguments
II 209f KripkeVsIdentity Theory: imaginable: pain without a brain condition - this is difficult to exclude for materialists. - QuineVsKripke: that is only difficult if the materialist believes in metaphysical necessity. X 88 Identity Theory of Logic: Identity/Logic/Quine: Truths of Identity Theory Example "x = x", "Ey((x = y)" or "~(x = y . ~(y = x)))" ((s) symmetry of identity) are not suitable as logical truths according to our definitions of logical truth. Reason: they can be wrong if "=" is replaced by other predicates. Consequence: So should we not count identity to logic, but to mathematics? Together with ">" and "ε"? See >Equal sign. Identity/Logic/Quine: because of the logical truth you do not want to count identity to logic, but there are also reasons to associate it with logic: X 89 The identity theory is complete, there are complete proof procedures for the quantifier logic with identity. Identity Theory/Axioms/Goedel: if you add the axiom (1) x = x and the axiom scheme (2) ~(x = y . Fx . ~Fy) to a complete evidence procedure for the qunatum logic, this results in a complete evidence procedure for the quantifier logic with identity. Universality: this characteristic of identity theory also makes it closer to logic than to mathematics: it treats all objects without bias. This suggests that identity theory and quantifier logic are particularly fundamental._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
