The atavistic urge toward danger persists and its satisfaction is called adventure.

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

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.

How gloriously legible are the constellations of the heavens!

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

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

What one man can invent another can discover.

The eternal mystery of the world is its comprehensibility.

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