I havent actually read his book, but as he's described it, I thought that he was just sharing his view on subjectivism.
Biocentrism, as Robert Lanza says, is:
..."the view that life creates the universe instead of the other way around. In this new paradigm, life is not just an accidental byproduct of the laws of physics."
Isn't this just what subjectivism or solipsism say?
That only one's own mind is sure to exist?
If nothing outside the mind can be proven, then everything that is is inside the mind. And therefore the universe is just what you make of it because you can't have concepts outside of our own perception of them?
So what he's saying is that the universe we see is created by our body.
Which I think is just subjectivism. How else could this description of Biocentrism be read?
