Do you mean that because of its complexity, we are not able to define it due to practical reasons (i.e. no powerful enough computer exists)? If so, that’s something completely different. Consciousness cannot be defined with math or logic even in principle. Certain aspects of consciousness can’t be defined either, like qualia (for example, the sensation of a color). Many materialists would even say that consciousness doesn’t exist because of that, and it’s all just a delusion (to which I ask: who/what is this delusion experienced by?).

What properties of fire do you mean?
