Our psychobiological nature is characterized paradoxically by our limitedly having and not having
free will — our having this will and being subject to causes understood scientifically. Both
characteristics are necessary for an intelligible ethics, politics, and political science. In particular,
political science as a science must admit of our behavior being partially caused and of political
rights and responsibilities in virtue of our limited free will. Admitting of either only this will or
only the determinism is a central error of modern totalitarian ideology.
