“Stupidity and wisdom meet in the same centre of sentiment and resolution, in the suffering of human accidents.”

“The most certain sign of wisdom is cheerfulness. ”

“He who fears he will suffer, already suffers from his fear.”

“He who fears he shall suffer, already suffers what he fears.”

“Learned we may be with another man's learning: we can only be wise with wisdom of our own.”

“I speak to the paper, as I speak to the first person I meet.”

“It is a disaster that wisdom forbids you to be satisfied with yourself and always sends you away dissatisfied and fearful, whereas stubbornness and foolhardiness fill their hosts with joy and assurance.”
