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

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

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

New things are always ugly.

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

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

Science is a cemetery of dead ideas.

The eternal mystery of the world is its comprehensibility.

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

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

Appearances are a glimpse of the obscure.

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

The unknown is the largest need of the intellect.
