The eternal mystery of the world is its comprehensibility.

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

New things are always ugly.

What one man can invent another can discover.

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

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

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

There are truths that prove their discoverers witless.

How gloriously legible are the constellations of the heavens!

Science is a cemetery of dead ideas.

The unknown is the largest need of the intellect.

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

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