This episode of the podcast is about J.S. Mill's brilliant defense of several objections made to the principle of utility. He begins by offering a definition of the principle (also called
"the greatest happiness" principle) and he tells his readers that the principle rests on a foundational claim that happiness is the only thing desirable (all other things are desirable as means to happiness). But the main topic in the chapter is Mill' rebuttal of every criticism made by the opponents of utilitarianism. It is important to read this chapter carefully because this we learn more about utilitarianism here than at any other chapter of his book.
