There’s a reason they call it the “hard problem.

Consciousness: Where is it? What is it? No one single perspective seems to be able to answer all the questions we have about consciousness. Now Bernardo Kastrup thinks he’s found one. He calls his ontology idealism, and according to idealism, all of us and all we perceive are manifestations of something very much like a cosmic-scale dissociative identity disorder (DID). He suggests there’s an all-encompassing universe-wide consciousness, it has multiple personalities, and we’re them.

Kastrup’s paper is an attempt to devise an explanation for consciousness that leaves no unanswered questions behind as other commonly held perspectives do, at least at our current level of scientific knowledge. (Kastrup is a computer engineer specializing in AI and reconfigurable computing.)

Physicalism and substance dualism

There are a seemingly endless array of ultimately unsatisfying isms thrown at the problem of consciousness. If you’ve got some time, have a look at the Internet Encyclopedia of Philosophy. Here, though, if only to explain what panpsychism, the basis of Kastrup’s idealism, isn’t, it’ll be helpful to talk very briefly about two of the most popular ontologies to which it’s a response.

Physicalism describes the belief that consciousness is a product of interaction between different types of physical matter. For many, though, physicalism falls into a seemingly uncrossable chasm between strictly physical processes on one hand, and our “phenomenal experience” — the experience of experiencing — on the other. One is chemical, electrical, mechanical, and the other is…something else. Physical processes may be able to explain how we know a roaring fire is hot, but not what warmth feels like to us.

The clockwork brain

In substance dualism, there’s physical substance and immaterial substance, consciousness, and they’re two separate domains. This seems intuitively true to a lot of people — think body and soul — but if they are fundamentally different things, what means of exchange, or “language,” could they possibly have in common, and how could they interact? How could a physical experience make our consciousness feel a certain way, and how could a purely mental decision cause our body to take action? And where exactly could this happen?

Body and mind are separate things?


Take one dash of constitutive panpsychism

Kastrup’s system is based on an ontology growing popular with some philosophers, and with some physicists, called constitutive panpsychism. (We’ve explained this concept in greater detail before at Big Think.) It’s basically the idea that everything, all of the tiny subatomic particles that make up the universe’s mass, have consciousness, a sense of what it’s like to have an experience. We have consciousness because it’s everywhere. In this way, it’s all there is.
