True though this may have been in the past, it is true no longer. The science of our century has forged weapons of observation and analysis by which the veriest tyro may profit. Science has trained and fashioned the average mind into habits of exactitude and disciplined perception, and in so doing has fortified itself for tasks higher, wider, and incomparably more wonderful than even the wisest among our ancestors imagined. Like the souls in Plato's myth that follow the chariot of Zeus, it has ascended to a point of vision far above the earth. It is henceforth open to science to transcend all we now think we know of matter and to gain new glimpses of a profounder scheme of Cosmic law.
Address to the British Association for the Advancement of Science (1898)

As "Mr. Lee" in Enter the Dragon (1973); Bruce Lee's character said this to Robert Wall's character "O'Hara", after the latter had broken a board in the air with his fist in an act of attempted intimidation.

1950s, Loving Your Enemies (November 1957)
Context: I think the first reason that we should love our enemies, and I think this was at the very center of Jesus’ thinking, is this: that hate for hate only intensifies the existence of hate and evil in the universe. If I hit you and you hit me and I hit you back and you hit me back and go on, you see, that goes on ad infinitum. It just never ends. Somewhere somebody must have a little sense, and that’s the strong person. The strongperson is the person who can cut off the chain of hate, the chain of evil. And that is the tragedy of hate, that it doesn’t cut it off. It only intensifies the existence of hate and evil in the universe. Somebody must have religion enough and morality enough to cut it off and inject within the very structure of the universe that strong and powerful element of [[love].
