Man on the dubious waves of error toss'd.

Ah, poor our sex! this fault in us I find, The error of our eye directs our mind. What error leads must error.

So shall you hear Of carnal, bloody, and unnatural acts, Of accidental judgments, casual slaughters, Of deaths put on by cunning and forced cause, And, in this upshot, purposes mistook Fall'n on th' inventors' heads.

Mistake, error, is the discipline through which we advance.

It is not the errors of others, but our own miscalculations, on which we wreak our lasting vengeance. It is ourselves that we cannot forgive.

Spare feast! a radish and an egg.
