Eliminative materialism isn’t my thing no. Emergent materialism is what I roll with. So the human mind and culture and numbers are things that exist as emergent properties of other things.
Sure it could all be a lie with us living in the matrix or so on, and it’s fun to entertain such thoughts every now and then. But I won’t accept it as truth without a better reason than “but technically it’s possible”.
I know. The matrix (or any other metaphysical idealism for that matter) is an example of a situation where we cannot trust our perception for knowledge about the true nature of the universe (much like the allegory of the cave), although taken to the extreme. The epistemological and metaphysical aspects of Plato’s cave are very much intertwined.
