But what is an object? I agree that Unicorn can exist, in the mind of some people, or in a dream, but most would say that Unicorn do no exist, because being fictional is part of their definition. Or take a square circle, or a dog which is also a cat… The interesting things is what is the minimal amount of things that we have to assume in a theory so that we can derive the existence of all appearances, and of the laws to which they obey? How to get consciousness, how to get the appearance of matter and of physical laws. Assuming Mechanism, it can be proved that any Turing universal machinery will do the job, and that makes Mechanism testable: drive physics and compare with the observation. What must be searched is to relate the different notion of existence that we are willing to make sense of. > > To which someone might say something like: "But there is a red car parked in > front of my house.

A red car can't be blue; that would be a > contradiction, a violation of the law of identity, Why? A red can which is blue can be identical with itself. All odd natural number solution to 2x = x + 1 are equal to itself, despite not existing. Your self-identity criteria is too weak for being a criteria of existence. > and hence impossible.

OK with this.
