How gloriously legible are the constellations of the heavens!

Appearances are a glimpse of the obscure.

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

New things are always ugly.

What one man can invent another can discover.

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

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

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

Science is a cemetery of dead ideas.

The eternal mystery of the world is its comprehensibility.
