"Revolution is the negation of the existing, a violent protest against man's inhumanity to man with all the thousand and one slaveries it involves. It is the destroyer of dominant values upon which a complex system of injustice, oppression, and wrong has been built up by ignorance and brutality. It is the herald of NEW VALUES, ushering in a transformation of the basic relations of man to man, and of man to society."
