9 Richard Feynman Quotes on Truth

Richard Feynman quotes on truth

8. The chance is high that the truth lies in the fashionable direction. But, on the off chance that it is in another direction - a direction obvious from an unfashionable view of field theory - who will find it? Only someone who has sacrificed himself by teaching himself quantum electrodynamics from a peculiar and unfashionable point of view; one that he may have to invent for himself.

12. There is one feature I notice that is generally missing in 'cargo cult science'... It's a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty - a kind of leaning over backwards... For example, if you're doing an experiment, you should report everything that you think might make it invalid - not only what you think is right about it... Details that could throw doubt on your interpretation must be given, if you know them.

17. For a successful technology, reality must take precedence over public relations, for nature cannot be fooled.

51. The third aspect of my subject is that of science as a method of finding things out. This method is based on the principle that observation is the judge of whether something is so or not. All other aspects and characteristics of science can be understood directly when we understand that observation is the ultimate and final judge of the truth of an idea. But 'prove' used in this way really means 'test,' in the same way that a hundred-proof alcohol is a test of the alcohol, and for people today the idea really should be translated as, 'The exception tests the rule.' Or, put another way, 'The exception proves that the rule is wrong.' That is the principle of science. If there is an exception to any rule, and if it can be proved by observation, that rule is wrong.

53. The first ... has to do with whether a man knows what he is talking about, whether what he says has some basis or not. And my trick that I use is very easy. If you ask him intelligent questions - then he quickly gets stuck. It is like a child asking naive questions. If you ask naive but relevant questions, then almost immediately the person doesn't know the answer, if he is an honest man.

54. Looking back at the worst times, it always seems that they were times in which there were people who believed with absolute faith and absolute dogmatism in something. And they were so serious in this matter that they insisted that the rest of the world agree with them. And then they would do things that were directly inconsistent with their own beliefs in order to maintain that what they said was true.

57. Science is a way of trying not to fool yourself. The first principle is that you must not fool yourself, and you are the easiest person to fool.

61. Science is what we have learned about how not to fool ourselves about the way the world is.

69. It doesn't matter how beautiful your theory is, it doesn't matter how smart you are. If it doesn't agree with experiment, it's wrong.
