The proposal, sometimes known as biocentrism, and championed by an American doctor named Robert Lanza, protects us from an eternity of individual consciousness while still lifting us out of the meaninglessness of pure biology. Critics say that biocentrism is not a legitimate theory because it can’t be tested, but that doesn’t mean it’s wrong. If consciousness comprises an essential part of the physical universe, the very idea of testing its existence may be a logical impossibility.
