How gloriously legible are the constellations of the heavens!

The unknown is the largest need of the intellect.

What one man can invent another can discover.

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

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

There are truths that prove their discoverers witless.

Science is a cemetery of dead ideas.

I am tormented with an everlasting itch for things remote. I love to sail forbidden seas and land on barbarous coasts.

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

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

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

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

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