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

How gloriously legible are the constellations of the heavens!

Appearances are a glimpse of the obscure.

The unknown is the largest need of the intellect.

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

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.

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. 

What one man can invent another can discover.
