“We tend to think human knowledge as progressive; because we know more and more, our parents and grandparents are back numbers. But a contrary theory is possible - that we simply recognize different things at different times and in different ways.”

The Stark Munro Letters (1894)
Context: The more we progress the more we tend to progress. We advance not in arithmetical but in geometrical progression. We draw compound interest on the whole capital of knowledge and virtue which has been accumulated since the dawning of time. Some eighty thousand years are supposed to have existed between paleolithic and neolithic man. Yet in all that time he only learned to grind his flint stones instead of chipping them. But within our father's lives what changes have there not been? The railway and the telegraph, chloroform and applied electricity. Ten years now go further than a thousand then, not so much on account of our finer intellects as because the light we have shows us the way to more. Primeval man stumbled along with peering eyes, and slow, uncertain footsteps. Now we walk briskly towards our unknown goal.

Context: And I think one of the things that's important for bringing about further progress is that we listen to each other and we understand our differences. I don't think it's necessary for us to all speak one language, or all have the same foods, or all have the same customs. But I do believe that there are some universal principles that are important. I believe that the most important principle is a very simple one that is at the heart of most of the world’s great religions, which is treat somebody the same way you’d want to be treated. And if you start with that basic premise, then we will continue to make progress. But I also think that in order for us to make progress, we have to have that fellow feeling and we have to combine that with the use of our brains and reason, and our intellect. […] That requires not just a strong heart, but also using our heads. And if we do those two things, then I feel confident that we'll make progress.
