Philosophers categorize them as part of phenomenal consciousness. This form of consciousness seems mysterious, as it resists scientific explanation and seems irreducible to brain processes. Our phenomenally conscious experiences are presented to us intimately and directly when we have them, while remaining imperceptible to others.House of Mirrors defends a radical view cutting through the mysteries and known as illusionism: the idea that phenomenal consciousness is not real and only seems real because we are under an introspective illusion generated by our brains. This illusion is unique: it is stronger and much harder to grasp than other illusions, such as perceptual illusions. François Kammerer argues for illusionism and proposes a novel framework called Meta-Cartesianism, which explains why the illusion of phenomenal consciousness is unique and almost inextricable. Kammerer also maps the implications of the illusionist view in various domains: if phenomenal consciousness is illusory, what happens to the cognitive science of consciousness? What happens to ethics, given that phenomenal experiences seem crucial to well-being and moral status? What happens to epistemology, given that these experiences seem key to justification? House of Mirrors represents an important and bold new contribution to the study of consciousness.
