Science is a cemetery of dead ideas.

The unknown is the largest need of the intellect.

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.

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

There are truths that prove their discoverers witless.

What one man can invent another can discover.

The eternal mystery of the world is its comprehensibility.

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