It becomes a bit clearer in this video. He believes the universe exists independently of our consciousness but not on a material basis. Rather the independent basis of the universe is the collective consciousness of all entities. In other words, presumably if there were no conscious agents then there would be no material universe.
It makes sense to start with consciousness because the one thing we are sure about is that we are conscious. I am sure that I feel like I am sitting on a chair, for example. More sure about this than I am about the material reality of the chair itself. Materialism subverts this common sense view and seems to suggest that we should be more sure about the chair’s indepdenent existence than our own sensation of it. There does seem to be something wrong with that view of reality.
