And then to come to the subject of morals. These also are customs--divergent to the last degree among different races, at different times, or in different localities; customs for which it is often difficult to find any ground in reason or the "fitness of things." Thieving is supposed to be discountenanced among us, yet our present-day trade-morality sanctions it in a thousand different forms; and the respectable usurer (who can hardly be said to be other than a thief) takes a high place at the table of life. To hunt the earth for game has from time immemorial been considered the natural birthright and privilege of man, until the landlord class (whom wicked Socialists now denounce!) invented the crime of poaching and hanged men for it. As to marriage customs, in different times and among different peoples, they have been simply innumerable. And here the sense of inviolability in each case is most powerful. The severest penalties, the most stringent public opinion, biting deep down into the individual conscience, enforce the various codes of various times and places; yet they all contradict each other. Polygamy in one country, polyandry in the next; brother and sister marriage allowed at one time, marriage with your mother's cousin forbidden at another; prostitution sacred in the temples of antiquity, trampled under foot in the gutters of our great cities of to-day; monogamy respectable in one land, a mark of class-inferiority in another; celibacy scorned by some sections of people, accepted as the highest state by others; and so on.
