Diary of a Plague Year

Unless we put medical freedom into the Constitution, the time will come
when medicine will organize into an undercover dictatorship to restrict
the art of healing to one class of Men and deny equal privileges to
others; the Constitution of the Republic should make a Special
privilege for medical freedoms as well as religious freedom.
Benjamin Rush

Tyranny is always based on a mythological causality — on locating the source of a plague or scourge. Emergency powers are justified by the claim that you’ve located the source of what is destroying society from within.
