What is the difference between totalitarianism and dictatorship? What is an unjust law, and how do you identify it? What makes some people more prone to being manipulated than others? And what is the antidote to tyranny?

We speak with Dr. Aaron Kheriaty, author of “The New Abnormal: The Rise of the Biomedical Security State,” a former psychiatry professor at the University of California Irvine, and the former director of the medical ethics program at UCI Health. Now, he is a fellow and director of the Program in Bioethics and American Democracy at the Ethics and Public Policy Center.

Dr. Kheriaty is also one of the plaintiffs in the landmark Missouri v. Biden free speech case.
