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

There are truths that prove their discoverers witless.

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

New things are always ugly.

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.

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

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

Most new discoveries are suddenly-seen things that were always there.

How gloriously legible are the constellations of the heavens!
