Context

“To these special wants must be attributed the modifications which affect in various degrees and in different countries the mode of considering human actions, and the estimate which ought to be formed of them. It is the general and permanent interest of mankind that men should not kill each other: but it may happen to be the peculiar and temporary interest of a people or a class to justify, or even to honor, homicide. Honor is simply that peculiar rule, founded upon a peculiar state of society, by the application of which a people or a class allot praise or blame.” source
