Nature has planted in our minds an insatiable desire to seek the truth.

What one man can invent another can discover.

Science is a cemetery of dead ideas.

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

How gloriously legible are the constellations of the heavens!

Appearances are a glimpse of the obscure.

What one man can invent another can discover.

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

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

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

The eternal mystery of the world is its comprehensibility.

New things are always ugly.

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