This paper is in three parts. In the first part, I consider Maritain’s definition of freedom. He differentiates between two types of freedom: freedom of choice, which he also calls freedom from necessity, and freedom of autonomy or terminal freedom, also called freedom from constraint. The second part considers the three types of political philosophy of freedom identified by Maritain. They may respectively be called liberal individualism, statesponsored collectivism, and communal and personalist philosophy. The third political philosophy, communal and personalist, is advocated by Maritain. In the third part of this paper, I raise concerns about losses of freedom that have become more evident in the last few years during the COVID-19 pandemic, and I reflect upon how Maritain’s philosophy of freedom may apply in our contemporary situation.
