Appearances are a glimpse of the obscure.

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

New things are always ugly.

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

Nature has planted in our minds an insatiable desire to seek the truth.

Science is a cemetery of dead ideas.

The unknown is the largest need of the intellect.

What one man can invent another can discover.

What one man can invent another can discover.

The eternal mystery of the world is its comprehensibility.

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

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

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