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

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

New things are always ugly.

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

The eternal mystery of the world is its comprehensibility.

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.

What one man can invent another can discover.

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

Science is a cemetery of dead ideas.

Appearances are a glimpse of the obscure.

The unknown is the largest need of the intellect.
