The circumstances of the world are so variable that an irrevocable purpose or opinion is almost synonymous with a foolish one.

Our opinion of others is not so variable as our opinion of ourselves.

Circumstances and outcome are always variable.

Better a witty fool than a foolish wit.

It is great to shake off the trammels of the world and of public opinion . . . and become the creature of the moment . . . known by no other title than The Gentleman in the Parlour!

The only reason people do not know much is because they do not care to know. They are incurious. Incuriousity is the oddest and most foolish failing there is.
