ABSTRACT
MORAL PHILOSOPHY is often written as though the history of the subject were only of secondary and incidental importance. This attitude seems to be the outcome of a belief that moral concepts can be examined and understood apart from their history. Some philosophers have even written as if moral concepts were a timeless, limited, unchanging, determinate species of concept, necessarily having the same features throughout their history, so that there is a part of language waiting to be philosophically investigated which deserves the title “the language of morals” (with a definite article and a singular noun). In a less sophisticated way, historians of morals are all too apt to allow that moral practices and the content of moral judgments may vary from society to society and from person to person, but at the same time these historians have subtly assimilated different moral concepts-and so they end up by suggesting that although what is held to be right or good is not always the same, roughly the same concepts of right and good are universal.
