Even if we ignore the 'non-theoretical' knowledge which we acquire through experience (such as the knowledge of what something tastes like) and concentrate on theoretical knowledge, there is no good reason to think that physics can literally give the theory of everything. Here I want to be really pedantic. Although everything may be subject to physical law, not everything can be explained or described in physical terms. Physics has literally nothing to say about society, morality and the mind, for example - but of course these are parts of 'everything'.
Tim CraneThere's that great Irish joke: a man is lost in the countryside, stops a passer-by: 'how do I get to Dublin?'. The passer-by says 'well, I wouldn't start from here'. Rather than starting by talking in the abstract about materialism, dualism, 'material stuff' and things like that in regard to the mind, I would rather start from somewhere else.
Tim CraneI'm not a militant atheist, just an atheist. In fact, in a largely atheist country like the UK I think it's a bit silly to be a militant atheist.
Tim CraneI do think it's important to distinguish between intentionalism about consciousness and externalism about consciousness. Intentionalism says that consciousness is a form of intentionality - the representation of things to the mind. Externalism says that these things have to exist in order for them to be represented, or presented. These are different views.
