What one man can invent another can discover.

Science is a cemetery of dead ideas.

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

How gloriously legible are the constellations of the heavens!

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

Appearances are a glimpse of the obscure.

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

When they shout “Long live progress,” always ask, “Progress of what?”

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

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