There are truths that prove their discoverers witless.

What one man can invent another can discover.

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

Appearances are a glimpse of the obscure.

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. 

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.

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

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