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

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

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

How gloriously legible are the constellations of the heavens!

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

There are truths that prove their discoverers witless.

New things are always ugly.

Science is a cemetery of dead ideas.

Appearances are a glimpse of the obscure.

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