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

There are truths that prove their discoverers witless.

What one man can invent another can discover.

Appearances are a glimpse of the obscure.

One doesn’t discover new lands without consenting to lose sight of the shore for a very long time.

The unknown is the largest need of the intellect.

Science is a cemetery of dead ideas.

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

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

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

New things are always ugly.

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

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