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

What one man can invent another can discover.

New things are always ugly.

How gloriously legible are the constellations of the heavens!

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

Science is a cemetery of dead ideas.

The eternal mystery of the world is its comprehensibility.

Appearances are a glimpse of the obscure.

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

There are truths that prove their discoverers witless.

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

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

The discovery of a new dish does more for human happiness than the discovery of a star.
