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

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

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

There are truths that prove their discoverers witless.

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

The atavistic urge toward danger persists and its satisfaction is called adventure.

Science is a cemetery of dead ideas.

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

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

New things are always ugly.
