Science is a cemetery of dead ideas.

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

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

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

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

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

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

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

New things are always ugly.

The eternal mystery of the world is its comprehensibility.

How gloriously legible are the constellations of the heavens!

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

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