The unknown is the largest need of the intellect.

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

There are truths that prove their discoverers witless.

Science is a cemetery of dead ideas.

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

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.

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

The eternal mystery of the world is its comprehensibility.

New things are always ugly.

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

One sees great things from the valley; only small things from the peak.

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