"'The truth about the world about us.' 'Truth' is a word used in many different ways - 'You’re not telling the truth.' 'The truth about conditions in Russia.' 'Beauty is truth, truth beauty.' I want to use it here in the sense of what lies behind and outward show. I.et me hasten to explain by giving an example. The sun rises in the east and sets in the west. That is what we see; that is the ‘outward show'. In the past the outward show was regarded as the truth. But then a scientist came along to question it and then to announce that the truth was quite different from the appearance: the truth was that the earth revolved and the sun remained still -the outward show was telling a lie. The curious thing about scientific truths like this is that they often seem so useless. It makes no difference to the average man whether the sun moves or the earth moves. He still has to rise at dawn and stop work at dusk. But because a thing is useless it does not mean that it is valueless. Scientists still think it worthwhile to pursue truth. They do not expect that laws of gravitation and relativity are going to make much difference to everyday life, but they think it is a valuable activity to ask their eternal questions about the universe. And so we say that truth - the thing they are looking for—is a value."
