On algebraic naturalism and metaphysical indeterminacy in quantum mechanics.

I propose a technique for identifying fundamental properties using structures already present in physical theories. I argue that, in conjunction with a particular naturalistic commitment, that I dub 'algebraic naturalism', these structures can be used to generate a standard of metaphysical determinacy. This standard can be used to rule out the possibility of a virulent strain of 'deep' metaphysical indeterminacy that has been imputed to quantum mechanics.
