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

Appearances are a glimpse of the obscure.

There are truths that prove their discoverers witless.

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

What one man can invent another can discover.

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

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

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

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.
