For this time of looming conflict and for those conflicts our descendants will know as they go through the inescapable cycles of humanity and civilization. The Eternal War integrates a large part of the deep knowledge across multiple domains, which humanity has attained across the last two centuries. From this, The Eternal War presents a simple and yet powerful set of first principles related to who and what we are, so that we might finally cast aside the old labels of us and them, of us versus them, and better recognize the simple yet profound underlying forces at play in all living systems, across all time. But more so, that we may minimize the destruction during what now seems to be yet another inevitable all-out conflict between humanists and anti-humanists.
