The philosophy of materialism is confirmed and re-confirmed every day by all natural sciences. The belief that the source of all idealism, religion, is now solely relegated to the uneducated, the reactionary worshippers of Abraham, the cross, the blood and the mental backwash of nationalism and modern tribalism.
Their is no longer any question how our consciousness, our conscience, our mind, our psychology, our character, our social reality are formed. It is by the daily way we physically, socially, produce and re-produce our physical, social and psychological reality as human beings. We killed God in the last year of our Lord, 1945, by the mechanized, bureaucratized scientific slaughter of human beings, first at Auschwitz and then at Hiroshima.
The only real question is what kind of human beings have we created?
