The trailblazers in human, academic, scientific, and religious freedom have always been nonconformists. In any cause that concerns the progress of mankind, put your faith in the nonconformist!

I invented nothing new. I simply assembled the discoveries of other men behind whom were centuries of work. Had I worked fifty or ten or even five years before, I would have failed. So it is with every new thing. Progress happens when all the factors that make for it are ready, and then it is inevitable. To teach that a comparatively few men are responsible for the greatest forward steps of mankind is the worst sort of nonsense.

The moral philosophy and spiritual conceptions of men and nations should hold their own amid these formidable scientific evolutions...No material progress, even though it takes shapes we cannot now conceive, or however it may expand the faculties of man, can bring comfort to his soul.

Of all the small nations of this earth, perhaps only the ancient Greeks surpass the Scots in their contribution to mankind.

The human race cannot make progress without idealism.

No two cities have counted more with mankind than Athens and Jerusalem. Their messages in religion, philosophy, and art have been the main guiding lights of modern faith and culture.
