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

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.

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

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

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

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

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

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

New things are always ugly.

What one man can invent another can discover.

The unknown is the largest need of the intellect.

The atavistic urge toward danger persists and its satisfaction is called adventure.
