What one man can invent another can discover.

How gloriously legible are the constellations of the heavens!

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

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

Most new discoveries are suddenly-seen things that were always there.

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

The unknown is the largest need of the intellect.

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

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

New things are always ugly.
