“A book is a mirror: If an ass peers into it, you can't expect an apostle to look out”

“An excellent man, like precious metal, is in every way invariable; A villain, like the beams of a balance, is always varying, upwards and downwards”

“Just as we outgrow a pair of trousers, we outgrow acquaintances, libraries, principles, etc., at times before they're worn out and times - and this is the worst of all - before we have new ones”

“Even truth needs to be clad in new garments if it is to appeal to a new age”

“It often takes more courage to change one's opinion than to stick to it”

“Progress, under whose feet the grass mourns and the forest turns into paper from which newspaper plants grow, has subordinated the purpose of life to the means of subsistence and turned us into the nuts and bolts for our tools”
