Identism:
The doctrine taught by Schelling, that matter and mind, and subject and object, are identical in the Absolute; -- called also the system / doctrine of identity.

Functionalism (an alternative to extreme identism, which says that mind--a collection of matter--is identical with brain) maintains that the matter of the brain is irrelevant; "Only organization is important. Functionalism thinks of the relation between mind and brain as analogous to that between the software (program) and the hardware in a computer. . . . [Yet] the mind is in some sense identical with the brain."
