Some of mankind's most terrible misdeeds have been committed under the spell of certain magic words or phrases.

He who enters a university walks on hallowed ground.

Behavior which appears superficially correct but is intrinsically corrupt always irritates those who see below the surface.

Science advances, not by the accumulation of new facts, but by the continuous development of new concepts.

Public education is a great instrument of social change. Through it, if we so desire, we can make our country more nearly a democracy without classes. To do so will require the efforts of us all-teachers, administrators, taxpayers and statesmen. Education is a social process, perhaps the most important process in determining the future of our country; it should command a far larger portion of our national income than it does today.

Science emerges from the other progressive activities of man to the extent that new concepts arise from experiments and observations, and that the new concepts in turn lead to further experiments and observations.

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.
