Science is what we have learned about how to keep from fooling ourselves.
Interpretation
Science helps us understand the truth and avoid self-deception.
Richard P. Feynman's quote highlights the essence of science as a discipline aimed at uncovering reality. Instead of being misled by our biases or misconceptions, science encourages a systematic approach to learning and understanding the world around us, enabling individuals to critically assess information and arrive at valid conclusions.
In practice
In a college lecture on critical thinking, this quote can be used to emphasize the importance of skepticism in scientific inquiry.
The philosophical question before us is, when we make an observation of our track in the past, does the result of our observation become real in the same sense that the final state would be defined if an outside observer were to make the observation?
We seem gradually to be groping toward an understanding of the world of subatomic particles, but we really do not know how far we have yet to go in this task.
The first principle is that you must not fool yourself and you are the easiest person to fool.
It has not yet become obvious to me that there's no real problem. I cannot define the real problem; therefore, I suspect there's no real problem, but I'm not sure there's no real problem.
For far more marvelous is the truth than any artists of the past imagined it. Why do the poets of the present not speak of it? What men are poets who can speak of Jupiter if he were a man, but if he is an immense spinning sphere of methane and ammonia must be silent?
Science is a way to teach how something gets to be known, what is not known, to what extent things are known (for nothing is known absolutely), how to handle doubt and uncertainty, what the rules of evidence are, how to think about things so that judgments can be made, how to distinguish truth from fraud, and from show.
Scientists in different disciplines don't speak the same language. They publish in different journals. It's like the United Nations: You come together, but no one speaks the same language, so you need some translators.
Every great advance in natural knowledge has involved the absolute rejection of authority.
Fudging the data in any way whatsoever is quite literally a sin against the holy ghost of science. I'm not religious, but I put it that way because I feel so strongly. It's the one thing you do not ever do. You've got to have standards.
Well, biology today as I see it has an amiable look - quite different from the 19th-century view that the whole arrangement of nature is hostile, 'red in tooth and claw.' That came about because people misread Darwin's 'survival of the fittest.'
The significant chemicals of living tissue are rickety and unstable, which is exactly what is needed for life.
Among other things, neuroplasticity means that emotions such as happiness and compassion can be cultivated in much the same way that a person can learn through repetition to play golf and basketball or master a musical instrument, and that such practice changes the activity and physical aspects of specific brain areas.
