Mistakes

Definition

With hindsight, any decision that has unintended consequences may be considered to have been a mistake. It is more useful, however, to define a mistake as a misguided decision, whatever its consequences. The unintended consequence that is to be expected of a misguided decision may be avoided by chance; and chance may result in an unintended consequence that could not have been anticipated. A driver may escape a collision when he crosses a busy junction against a red light. He may also be the victim of someone else who does so - but in that case, his decision to cross the junction legally cannot usefully be considered to have been a mistake, despite its unintended consequence.
