Leonardo da Vinci

Our life is made by the death of others.

The greatest deception men suffer is from their own opinions.

Experience does not err. Only your judgments err by expecting from her what is not in her power.

He who does not punish evil commands it to be done.

Once you have tasted flight, you will forever walk the earth with your eyes turned skyward, for there you have been, and there you will always long to return.
