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.

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

Every man takes the limits of his own field of vision for the limits of the world.

The unknown is the largest need of the intellect.

How gloriously legible are the constellations of the heavens!

What one man can invent another can discover.

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

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

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