What one man can invent another can discover.

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

I am tormented with an everlasting itch for things remote. I love to sail forbidden seas and land on barbarous coasts.

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

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

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

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

I learned to make my mind large, as the universe is large, so that there is room for paradoxes.

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

Appearances are a glimpse of the obscure.
