What is token type identity theory?

Token Identity theories hold that every concrete particular falling under a mental kind can be identified with some physical (perhaps neurophysiological) happening or other: instances of pain, for example, are taken to be not only instances of a mental state (e.g., pain), but instances of some physical state as well ( …

What is a Type in philosophy?

Learn about this topic in these articles: Peirce therefore calls a a type (i.e., a formula for producing tokens). In philosophy of mind: Types and tokens. ) Thoughts regarded as propositions are clearly shareable. Two people can have the same thought—e.g., that snow is white.

What is the brain state identity thesis?

The mind-brain identity theory (or identity thesis) is the assertion that mental states/events/processes are identical to brain states/events/processes. The analytic identity thesis appears for the first time in Lewis 1966, then in Armstrong 1968.

What is the difference between functionalism and identity theory?

Functionalism is stated as looking at the relationships between mental states, sensory stimulation, and behavior. And Identity Theory looks says all mental states are representative of some physical states, that interact with each other.

Which is an example of token token identity theory?

…of what was called “token-token” identity theory. According to this view, particular instances or occurrences of mental states, such as the pain felt by a particular person at a particular time, are identical with particular physical states of the brain or central nervous system. Even this version of the…

Is it possible to have a type-type identity theory?

The variable realization of the mental by the physical appears to make this a real possibility, although the issue is delicate, since there are different ways of drawing up the types or kinds of event in question. An identity theory that disclaims type-type correlations is a token-token identity theory. See also type-token ambiguity.

What is the difference between a type and its tokens?

The distinction between a type and its tokens is a useful metaphysical distinction. In §1 it is explained what it is, and what it is not. Its importance and wide applicability in linguistics, philosophy, science and everyday life are briefly surveyed in §2.

How are mental states related to type type identity?

We have argued that functionally-oriented identity theorists can and should make, in addition to the first two claims, the third type-type identity claim that mental states are brain states. Consequently a token brain state is a token of pain in a derivative sense.
