Frase de René Descartes

“It is not enough to have a good mind; the main thing is to use it well.”

“The reading of all good books is like a conversation with the finest minds of past centuries.”

“The greatest souls are capable of the greatest vices as well as the greatest virtues.”

“Reason is the only thing that makes us men and distinguishes us from the animals.”

“I think, therefore I am.”
