In conditions of private property … “life-activity” stands in the service of property instead of property standing the service of free life-activity. - Herbert Marcuse

When the whole is at stake, there is no crime except that of rejecting the whole, or not defending it. … Those who identify themselves with the whole, who are installed as the leaders and defenders of the whole can make mistakes, but they cannot do wrong—they are not guilty. They may become guilty again when this identification no longer holds, when they are gone.

If man has learned to see and know what really is, he will act in accordance with truth, Epistemology is in itself ethics, and ethics is epistemology.
