Is there really such a thing as moral progress? Do we get any better as time goes on? It is a question which must often exercise the minds of those who reflect on moral questions at all. And it is a frequent topic of discussion, both in private conversations and in the written contributions of a good many of our popular philosophers. Of some of these contributions one may safely say that their chief value is as a warning against the dangers of hasty generalization on a subject such as this. And, taking advantage of such a warning, I shall make no attempt to give a final or dogmatic answer to this question. All I can try to do, within the limits of a single lecture, is to disentangle some of the most important considerations that seem to be in people's minds in discussing this question, and to estimate their importance as arguments on one side or the other.
