Abstract

I would like to begin by congratulating Arash Abizadeh. Hobbes and the Two Faces of Ethics is a splendid book. Even where I have disagreed with Abizadeh, the book has been a great help to me in framing central issues and in setting out pressing questions for different interpretations. I am sure that it will be a valuable resource for students of Hobbes for many years. Here I will discuss Abizadeh’s views on the science of morality in Hobbes, and I will focus on his Chapter 3. I will begin from the principles that form the basis of that science and proceed to its conclusions, the laws of nature. In both cases, although I recognize the difficulties that Abizadeh has presented for what he calls subjectivism, I am also concerned about the alternative interpretation that he defends. On that interpretation, prudentialism, the view that one ought to desire and pursue one’s own good, is a foundational principle of moral science, which gives us reason to follow the laws of nature. The principle is distinct from any particular desire or knowledge, but its practical importance is guaranteed by epistemic access to the laws of nature: any sane adult can easily know the laws of nature.
