Physicalism

Realisation physicalism Closely related to supervenience physicalism, is realisation physicalism, the thesis that every instantiated property is either physical or is realised by a physical property.

Unlike token physicalism, type physicalism entails supervenience physicalism.

Furthermore, there are differences expressed concerning the modal status of physicalism; whether it is a necessary truth, or is only true in a world which conforms to certain conditions (i.e. those of physicalism).

So any supervenience-based formulation of physicalism will at best state a necessary but not sufficient condition for the truth of physicalism.

Also, physicalism defined in terms of supervenience does not entail that all properties in the actual world are type identical to physical properties.

A natural question for physicalists, then, is whether the truth of physicalism is deducible a priori from the nature of the physical world (i.

Applied in the same way, statement 2 is the claim that physicalism is true at a possible world w if and only if any world that is a physical duplicate of w (without any further changes), is duplicate of w without qualification.

Because a high-level language is a practical requirement for developing the most complex programs, functionalism implies that a non-reductive physicalism would offer a similar advantage over a strictly eliminative materialism.

Both the definition of "physical" and the meaning of physicalism have been debated.

Chalmers, 1996 Adopting the former suggestion here, we can reformulate statement 1 as follows: 2) Physicalism is true at a possible world w if and only if any world that is a minimal physical duplicate of w is a duplicate of w simpliciter.

Common arguments against physicalism include both the philosophical zombie argument and the multiple observers argument, that the existence of a physical being may imply zero or more distinct conscious entities.

Emergentism main Supervenience physicalism has been seen as a form of emergentism, in which the subject's psychological experience is considered genuinely novel.

For example, if philosophical physicalism is true, a physical TOE will coincide with a philosophical theory of everything.

If this is correct, then we should (arguably) conclude that conceivability does not entail metaphysical possibility, and P2) of the conceivability argument against physicalism is false.

In philosophy, physicalism is the ontological thesis that "everything is physical", that there is "nothing over and above" the physical, See Smart, 1959 or that everything supervenes on the physical.

In practice, it is frequently assimilated to one variety of physicalism or another.

In the context of physicalism, the reductions referred to are of a "linguistic" nature, allowing discussions of, say, mental phenomena to be translated into discussions of physics.

One response to this problem is to abandon statement 2 in favour of the alternative possibility mentioned earlier in which supervenience-based formulations of physicalism are restricted to what David Chalmers (1996) calls "positive properties".

Others use the terms "materialism" and "physicalism" interchangeably.
