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

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.

New things are always ugly.

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

The eternal mystery of the world is its comprehensibility.

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

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

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

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