Self-defeating Theories
Part 1 argues that certain ethical theories are self-defeating. One such theory is ethical egoism, which Parfit claims is 'collectively self-defeating' due to the prisoner's dilemma. Ultimately, Parfit rejects "common sense morality" on similar grounds.
In this section, Parfit does not explicitly endorse a particular view; rather, he shows what the problems of different theories are. His only positive endorsement is of "impersonal ethics" – impersonality being the common denominator of the different parts of the book.

Famous quotes containing the word theories:
“In the course of a life devoted less to living than to reading, I have verified many times that literary intentions and theories are nothing more than stimuli and that the final work usually ignores or even contradicts them.”
—Jorge Luis Borges (1899–1986)
