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.

Every man has his moral backside which he refrains from showing unless he has to and keeps covered as long as possible with the trousers of decorum.

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

A book is a mirror: if an ape looks into it an apostle is hardly likely to look out.

The Greeks possessed a knowledge of human nature we seem hardly able to attain to without passing through the strengthening hibernation of a new barbarism.

Just as the performance of the vilest and most wicked deeds requires spirit and talent, so even the greatest demand a certain insensitivity which under other circumstances we would call stupidity.
