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.

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

Science is a cemetery of dead ideas.

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

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

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

New things are always ugly.

There are truths that prove their discoverers witless.

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

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

The unknown is the largest need of the intellect.

Appearances are a glimpse of the obscure.
