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

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

There are truths that prove their discoverers witless.

The eternal mystery of the world is its comprehensibility.

How gloriously legible are the constellations of the heavens!

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.

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

Appearances are a glimpse of the obscure.

The unknown is the largest need of the intellect.
