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!

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

Appearances are a glimpse of the obscure.

When they shout “Long live progress,” always ask, “Progress of what?”

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

There are truths that prove their discoverers witless.

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.

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