Life consists in penetrating the unknown, and fashioning our actions in accord with the new knowledge thus acquired.

True knowledge exists in knowing that you know nothing.

Never be afraid of not knowing. Find out.

Happy will they be who lend ear to the words of the dead.

All knowledge which ends in words will die as quickly as it came to life, with the exception of the written word: which is its mechanical part.

The acquisition of knowledge is always of use to the intellect, because it may thus drive out useless things and retain the good. For nothing can be loved or hated unless it is first known.
