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

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

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

New things are always ugly.

What one man can invent another can discover.

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

Science is a cemetery of dead ideas.

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

There are truths that prove their discoverers witless.

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