What one man can invent another can discover.

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

New things are always ugly.

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

What one man can invent another can discover.

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

They are ill discoverers that think there is no land, when they can see nothing but sea.

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

Nature has planted in our minds an insatiable desire to seek the truth.

The eternal mystery of the world is its comprehensibility.

How gloriously legible are the constellations of the heavens!

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

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