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

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

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

There are truths that prove their discoverers witless.

What one man can invent another can discover.

Science is a cemetery of dead ideas.

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

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.

The unknown is the largest need of the intellect.
