The mind is not the brain. The locus of our consciousness is in the world. Portalism embraces radical phenomenal externalism and represents a contemporary form of dualism that rejects materialist assumptions of mind/brain identity. As a philosophy of mind, Portalism breaks with traditional thinking in two significant ways: first by holding that consciousness is in fact a fifth fundamental force of nature endowed with behavioural attributes not unlike that of gravity, and second by arguing how consciousness inheres in all living organisms regardless of their biological sophistication. Portalism compels us to reject traditional monist theories about the nature of consciousness and boldly enter into a new way of thinking about our own reality.
