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

Science is a cemetery of dead ideas.

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

There are truths that prove their discoverers witless.

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

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

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

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

How gloriously legible are the constellations of the heavens!

Appearances are a glimpse of the obscure.

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

What one man can invent another can discover.

New things are always ugly.
