Experience never errs; it is only your judgments that err by
promising themselves effects such as are not caused by your
experiments.

Experience does not err; only your judgments err by expecting from
her what is not in her power. Men wrongly complain of Experience;
with great abuse they accuse her of leading them astray but they set
Experience aside, turning from it with complaints as to our
ignorance causing us to be carried away by vain and foolish desires
to promise ourselves, in her name, things that are not in her power;
saying that she is fallacious. Men are unjust in complaining of
innocent Experience, constantly accusing her of error and of false
evidence.
