Beware

Of entrance to a quarrel; but being in,

Bear 't that the opposed may beware of thee.

Give every man thy ear, but few thy voice;

Take each man's censure, but reserve thy judgment.

Costly thy habit as thy purse can buy,

But not express'd in fancy; rich, not gaudy;

For the apparel oft proclaims the man.

William Shakespeare (1564-1616): Hamlet. Act i. Sc. 3.

Thus with the year

Seasons return; but not to me returns

Day, or the sweet approach of even or morn,

Or sight of vernal bloom or summer's rose,

Or flocks, or herds, or human face divine;

But cloud instead, and ever-during dark

Surrounds me; from the cheerful ways of men

Cut off, and for the book of knowledge fair

Presented with a universal blank

Of Nature's works, to me expung'd and raz'd,

And wisdom at one entrance quite shut out.

John Milton (1608-1674): Paradise Lost. Book iii. Line 40.
