“When I express my opinions it is so as to reveal the measure of my sight not the measure of the thing.”

“I care not so much what I am in the opinion of others, as what I am in my own.”

“The most fruitful and natural exercise for our minds is, in my opinion, conversation.”

“When I am attacked by gloomy thoughts,nothing helps me so much as running to my books.They quickly absorb me and banish the clouds from my mind.”

“The advantage of living is not measured by length, but by use; some men have lived long, and lived little; attend to it while you are in it. It lies in your will, not in the number of years, for you to have lived enough.”

“You never speak about yourself without loss. Your self-condemnation is always accredited, your self-praise discredited. There may be some people of my temperament, I who learn better by contrast than by example, and by flight than by pursuit. This was the sort of teaching that Cato the Elder had in view when he said that the wise have more to learn from the fools than the fools from the wise; and also that ancient lyre player who, Pausanias tells us, was accustomed to force his pupils to go hear a bad musician who lived across the way, where they might learn to hate his discords and false measures.”

“In truth, knowledge is a great and very useful quality; those who despise it give evidence enough of their stupidity. Yet I do not set its value at that extreme measure that some attribute to it, such as the philosopher Herillus, who find in it the sovereign good and think it has the power to make us wise and happy.”
