" So that is the problem of mind -- consciousness -- a vast, unchartable domain that includes all science, yet that science cannot deal with, has no way of approaching; not even to identify its presence or absence; that offers nothing to measure, and nothing to locate, since it has no location.

A few years ago it occurred to me -- albeit with some shock to my scientific sensibilities -- that my two problems, that of a life﷓breeding universe, and that of consciousness that can neither be identified nor located, might be brought together. That would be with the thought that mind, rather than being a late development in the evolution of organisms, had existed always: that this is a life﷓breeding universe because the constant presence of mind made it so.
