Ethics Through History

Abstract

This book is a selective discussion of the tradition in moral philosophy that runs from Socrates to the present. The main themes: (1) Plato, Aristotle, Epicurus, and the Stoics take different positions in debates the relation between morality (including right action and the character of virtuous agents) and the human good. Aquinas’ version of an Aristotelian view identifies the human good with the fulfilment of human nature and capacities in a just society. These facts about the human good can be discovered by rational reflexion on human nature and human needs. (2) These views both about the content of ethics and about the sources of ethical knowledge are questioned by Scotus and later writers on natural law. Voluntarists take the principles of natural law and moral right to be the products of will; naturalists take them to be discovered by reason. (3) The dispute about will and reason is the source of the long dispute between sentimentalists (Hutcheson, Hume) and rationalists (Butler, Price, Reid) about whether moral judgment has a non-rational or a rational basis. Kant tries to resolve this dispute. (4) These arguments lead to further discussion about what makes morally right actions right. Sentimentalists, followed by Mill and Sidgwick and by later utilitarians, argue that actions are right in so far as they maximize pleasure. Others, including the rationalists, Kant, Ross, and Rawls, argue that moral principles are not subordinate to utility.
