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

Appearances are a glimpse of the obscure.

Science is a cemetery of dead ideas.

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

How gloriously legible are the constellations of the heavens!

New things are always ugly.

True originality consists not in a new manner but in a new vision.

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

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

What one man can invent another can discover.
