How gloriously legible are the constellations of the heavens!

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

I am tormented with an everlasting itch for things remote. I love to sail forbidden seas and land on barbarous coasts.

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

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

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

Appearances are a glimpse of the obscure.

The unknown is the largest need of the intellect.

The eternal mystery of the world is its comprehensibility.

What one man can invent another can discover.
