"Before entering on the question of the relation of morality to our existing social environment, it will be advisable to inquire what we mean by moral progress, and what evidence there is that any such progress has occurred in recent times, or even within the period of well-established history. The belief was once prevalent, and is still held by many persons, that a knowledge of right and wrong is inherent or instinctive in everyone, and that the immoral person may be justly punished for such wrongdoing as he commits. But that this cannot be wholly, if at all, true is shown by the fact that in different societies and at different periods the standard of right and wrong changes considerably. We are obliged to conclude, therefore, that what is commonly termed morality is not wholly due to any inherent perception of what is right or wrong conduct, but that it is to some extent and often very largely a matter of convention, varying at different times and places in accordance with the degree and kind of social development which has been attained often under different and even divergent conditions of existence. The actual morality of a community is largely a product of the environment, but it is local and temporary, not permanently affecting the character. To bring together the evidence in support of this view, to distinguish between what is permanent and inherited and what is superficial and not inherited, and to trace out some of the consequences as regards what we term "morality" is the purpose of the present volume"--Introduction.
