An icebreaker
A Dutch philosopher and computer scientist argues that reality is fundamentally mental, with individual minds as dissociated fragments of one universal consciousness. He holds this as a rigorous alternative to physicalism; other philosophers argue his central move doesn't actually solve what it claims to.
Across his peer-reviewed papers and books, he has argued that mind is the only thing known directly to exist, and that treating it as fundamental avoids problems he says plague physicalist and panpsychist accounts of consciousness alike.
In public exchanges and essays responding directly to Kastrup, he argued for panpsychism over idealism, holding that basic physical entities themselves carry consciousness rather than being appearances of one larger cosmic mind.
Taking the illusionist position in exchanges with Kastrup, he maintained that the vivid, irreducible feel of experience Kastrup treats as bedrock is itself something a physical system can be built to represent, not proof mind is fundamental.
