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

Most new discoveries are suddenly-seen things that were always there.

There are truths that prove their discoverers witless.

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

How gloriously legible are the constellations of the heavens!

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

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

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

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

The unknown is the largest need of the intellect.

New things are always ugly.

What one man can invent another can discover.

The eternal mystery of the world is its comprehensibility.
