curiosità

I shall continue. I never tire of being useful.
Knowledge of all things is possible.
The greater the sensibility, the greater the suffering... much suffering
Man does not vary from the animals except in what is accidental.

I roamed the country side searching for answers to things I did not understand. Why shells existed on the tops of mountains along with the imprints of coral and plants and sea weed usually found in the sea. Why the thunder lasts a longer time than that which causes it, and why immediately on its creation the lightning becomes visible to the eye while thunder requires time to travel. How the various circles of water form around the spot which has been stuck by a stone. and why a bird sustains itself in the air. These questions and other strange phenomena engages my thoughts throughout my life.
