The same thing occurs in affairs of state; for by recognizing from afar the diseases that are spreading in the state (which is a gift given only to the prudent ruler), they can be cured quickly; but when, not having been recognized, they are not recognized and are left to grow to the extent that everyone recognizes them, there is no longer any cure.
