What one man can invent another can discover.

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

There are truths that prove their discoverers witless.

What one man can invent another can discover.

New things are always ugly.

The unknown is the largest need of the intellect.

The eternal mystery of the world is its comprehensibility.

Appearances are a glimpse of the obscure.

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

Science is a cemetery of dead ideas.

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

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

A man of genius makes no mistakes. His errors are volitional and are the portals of discovery.
