The unknown is the largest need of the intellect.

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

How gloriously legible are the constellations of the heavens!

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

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

Science is a cemetery of dead ideas.

What one man can invent another can discover.

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

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

Appearances are a glimpse of the obscure.

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

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

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