No man can be said to be perfectly happy that runs the risk of disappointment: which is the case of every man that _fears_ or _hopes_ for anything. For _hope_ and _fear_, how distant soever they may seem to be the one from the other, they are both of them yet coupled in the same chain, as the guard and the prisoner; and the one treads upon the heels of the other. The reason of this is obvious, for they are passions that look forward, and are ever solicitous for the future; only _hope_ is the more plausible weakness of the two, which in truth, upon the main, are inseparable; for the one cannot be without the other: but where the _hope_ is stronger than the _fear_, or the _fear_ than the _hope_, we call it the one or the other; for without _fear_ it were no longer _hope_, but _certainty_; as without _hope_ it were no longer _fear_ but _despair_.
