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

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. 

Science is a cemetery of dead ideas.

What one man can invent another can discover.

One sees great things from the valley; only small things from the peak.

New things are always ugly.

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

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

The unknown is the largest need of the intellect.

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

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

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