When they shout “Long live progress,” always ask, “Progress of what?”

New things are always ugly.

What one man can invent another can discover.

The unknown is the largest need of the intellect.

I learned to make my mind large, as the universe is large, so that there is room for paradoxes.

There are truths that prove their discoverers witless.

True originality consists not in a new manner but in a new vision.

One doesn’t discover new lands without consenting to lose sight of the shore for a very long time.

Research is formalized curiosity. It is poking and prying with a purpose. 

One sees great things from the valley; only small things from the peak.
