Space and time are the conceptions of theory, not of laws. They are neither necessary nor useful in the statement of the results of any experiment. - Norman Robert Campbell

Science is the study of those judgements concerning which universal agreement can be obtained.

Science, like art, should not be something extraneous, added as a decoration to other activities of existence; it should be part of them, inspiring our most trivial actions as well as our noblest thoughts.

Science would not be what it is if there had not been a Galileo, a Newton or a Lavoisier, any more than music would be what it is if Bach, Beethoven and Wagner had never lived. The world as we know it is the product of its geniuses—and there may be evil as well as beneficent genius—and to deny that fact, is to stultify all history, whether it be that of the intellectual or the economic world.
