Euphemisms are not, as many young people think, useless verbiage for that which can and should be said bluntly; they are like secret agents on a delicate mission, they must airily pass by a stinking mess with barely so much as a nod of the head, make their point of constructive criticism and continue on in calm forbearance. Euphemisms are unpleasant truths wearing diplomatic cologne.

Quentin Crisp

Ships that pass in the night, and speak each other in passing, Only a signal shown, and a distant voice in the darkness; So on the ocean of life, we pass and speak one another, Only a look and a voice, then darkness again and a silence.

Henry Wordsworth Longfellow

There are only two mistakes one can make along the road to truth; not going all the way, and not starting.

Buddha

As far as I'm concerned, I prefer silent vice to ostentatious virtue.

Albert Einstein

Everyone is a genius at least once a year. The real geniuses simply have their bright ideas closer together.

Georg Christoph Lichtenberg
