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

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

The atavistic urge toward danger persists and its satisfaction is called adventure.

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

Appearances are a glimpse of the obscure.

The discovery of a new dish does more for human happiness than the discovery of a star.

What one man can invent another can discover.

How gloriously legible are the constellations of the heavens!

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

A man of genius makes no mistakes. His errors are volitional and are the portals of discovery.
