The stumbling way in which even the ablest of the scientists in every generation have had to fight through thickets of erroneous observations, misleading generalizations, inadequate formulation, and unconscious prejudice is rarely appreciated by those who obtain their scientific knowledge from textbooks.

Education is what is left after all that has been learnt is forgotten.

There is only one proved method of assisting the advancement of pure science-that of picking men of genius, backing them heavily, and leaving them to direct themselves.

Whether a man lives or dies in vain can be measured only by the way he faces his own problems, by the success or failure of the inner conflict within his own soul. And of this no one may know save God.

Each honest calling, each walk of life, has its own elite, its own aristocracy based on excellence of performance. . . . There will always be the false snobbery which tries to place one vocation above another. You will become a member of the aristocracy in the American sense only if your accomplishments and integrity earn this appellation.

Therefore, a grotesque account of a period some thousands of years ago is taken seriously though it be built by piling special assumptions on special assumptions, ad hoc hypothesis [invented for a purpose] on ad hoc hypothesis, and tearing apart the fabric of science whenever it appears convenient. The result is a fantasia which is neither history nor science.
