Never lose a holy curiosity.

He who can no longer pause to wonder and stand rapt in awe, is as good as dead.

It is a miracle that curiosity survives formal education.

I have no special talents. I am only passionately curious.

I roamed the countryside searching for answers to things I did not understand. Why shells existed on the tops of mountains. How the various circles of water form around the spot which has been struck by a stone, and why a bird sustains itself in the air.

Having wandered some distance among gloomy rocks, I came to the entrance of a great cavern ... Two contrary emotions arose in me: fear and desire--fear of the threatening dark cavern, desire to see whether there were any marvelous things in it.
