Science is a cemetery of dead ideas.

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

What one man can invent another can discover.

New things are always ugly.

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

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

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

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

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!

The eternal mystery of the world is its comprehensibility.

They are ill discoverers that think there is no land, when they can see nothing but sea.

Appearances are a glimpse of the obscure.
