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

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

Science is a cemetery of dead ideas.

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

Appearances are a glimpse of the obscure.

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

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

New things are always ugly.

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

The eternal mystery of the world is its comprehensibility.

There are truths that prove their discoverers witless.

The unknown is the largest need of the intellect.

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