Your common sense is nothing more than the voices of thousands and thousands of these ghosts from the past. - Robert M. Pirsig

Plato finds it necessary to separate, for example, "horseness" from "horse" and say that horseness is real and fixed and true and unmoving, while the horse is a mere, unimportant, transitory phenomenon. Horseness is pure Idea. The horse that one sees is a collection of changing Appearances, a horse that can flux and move around all it wants to and even die on the spot without disturbing horseness, which is the Immortal Principle and can go on forever in the path of the Gods of old.

Of course, the laws of science contain no matter and have no energy either and therefore do not exist except in people's minds. It's best to be completely scientific about the whole thing and refuse to believe in either ghosts or the laws of science. That way you're safe. That doesn't leave you very much to believe in, but that's scientific too.

Dialectic, which is the parent of logic, came itself from rhetoric. Rhetoric is in turn the child of the myths and poetry of ancient Greece. That is so historically, and that is so by any application of common sense. The poetry and the myths are the response of a prehistoric people to the universe around them made on the basis of Quality. It is Quality, not dialectic, which is the generator of everything we know.
