“Without these experimental tests, very few physicists would have accepted general relativity. There are many hypotheses in physics of almost comparable brilliance and elegance that have been rejected because they did not survive such a confrontation with experiment. In my view, the human condition would be greatly improved if such confrontations and willingness to reject hypotheses were a regular part of our social, political, economic, religious and cultural lives.”

—  Carl Sagan

“The slow, the never ending approach to truth consists in perpetually forming and testing hypotheses, accepting those at which at the time seem to fit the facts and rejecting the others.”

“Newton's own motto, "hypotheses non fingo" was, in a sense, disregarded by Newton himself: he rejected hypotheses only where they violated his own "regula philosophandi", that is to say, his principle of their strict parsimony. In terms of present-day methodology, we reject hypotheses as scientifically meaningless if they are incapable even of indirect test; and we reject them as superfluous or as implausible if they are too complex and artificial to conform with well established canons of inductive probability. But freedom of scientific theorizing must be preserved wherever the conditions of meaningfulness and of economy appear to be satisfied.”

“We perceive clearly that theories and hypotheses are not accepted or rejected outright; they have their periods of activity, and then lie dormant for a time, only to be revived in a new form later on.”

“Both in the natural sciences and in sociology direct perception is deceptive, leading to the view that we are confronted with something which is in itself just what it appears to be. This is by no means the case and has long ago been rejected by the physical sciences, and it would be interesting to find out why it is still virtually unchallenged in sociology.”

“The overwhelming majority of theories are rejected because they contain bad explanations, not because they fail experimental tests.”

“You would have to ask a physicist really but I think understanding fundamental problems in physics is very important because they are part of our culture. You just never know what is going to come from it. If you had told Isaac Newton about spaceships and satellites that arise from his laws of gravity, it would have been science fiction to him.”

“Three precepts are offered to constitute a foundation for the use of laboratory experimental methods in testing hypotheses about the behavior of allocation mechanisms.”

“Could the Aboriginal and the British cultures have been reconciled when they first met? The prevailing view is that they could have signed a treaty and found a way of ­living together in relative ­harmony. I am not persuaded. The two confronting cultures, whether first living side by side at Sydney in 1788 or at Perth in 1829, had little in common except that they were the product of human beings. Their languages and religions differed. Their attitude to marriage, family, property and individual wealth, their economic and political systems, their way of fighting, and their thoughts about life and death, were far apart. In the world today no two cultures are so far apart as those that lived side by side in many Australian regions after 1788. Mecca and ­Washington today have far more in common than did the paternal ­Governor Phillip and the Aborigines whom he met in Sydney in 1788.”

“They detained me for 81 days, but they never killed me. They clearly told me: 'If we were in the Cultural Revolution, you would have been killed 100 times.' They said: 'We have already improved.' I said: 'I thank you very much. Yes, you have improved. Not because you are really willing to improve yourself, but only because improvement is a matter of surviving.”

“Of the many references to Newton in 18th-century electrical writings only a small number were to the Principia, the greater part by far were to the Opticks. This was true not alone of the electrical writings but also in other fields of experimental enquiry…. [The Opticks] would allow the reader to roam, with great Newton as his guide, through the major unresolved problems of science and even the relation of the whole world of nature to Him who had created it…. in the Opticks Newton did not adopt the motto… —Hypotheses non fingo; I frame no hypotheses—but, so to speak, let himself go, allowing his imagination full reign and by far exceeding the bounds of experimental evidence.”
