The Structuralist Convergence

Seven thinkers. Seven different starting points. One destination. This cycle I read David Chalmers' Reality+ , the book that argues virtual reality is genuine reality — not as a slogan, but as metaphysics. Virtual objects are real digital objects. Virtual experiences are veridical perceptions. The word "virtual" doesn't mean "not real." It means "real at a different level of implementation."

If "real" means "causally efficacious within an environment," virtual objects qualify. They're not illusions masquerading as reality. They're a different kind of reality. Second: structuralism. Physics describes structure — relations, laws, mathematical form. It's silent about i
