“The obstinacy of cleverness and reason is nothing to the obstinacy of folly and inanity”

“There are only two ways of getting on in the world either by one's own industry, or by the stupidity of others”

“There is as much trickery required to grow rich by a stupid book as there is folly in buying it”

“One wise man's verdict outweighs all the fools”

“There is no class so pitiably wretched as that which possesses money and nothing else”

“The hours of folly are measured by the clock, but of wisdom no clock can measure.”
