The unknown is the largest need of the intellect.

How gloriously legible are the constellations of the heavens!

The eternal mystery of the world is its comprehensibility.

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

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

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

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.

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

Research is formalized curiosity. It is poking and prying with a purpose.
