Conspiracies are discovered either by disclosures made, or by conjecture. Disclosures are made through the treachery or folly of those to whom you communicate your design. Treachery is to be looked for, because you can impart your plans only to such persons as you believe ready to face death on your behalf, or to those who are discontented with the prince. Of men whom you can trust thus implicitly, one or two may be found; but when you have to open your designs to many, they cannot all be of this nature; and their goodwill towards you must be extreme if they are not daunted by the danger and by fear of punishment. Moreover men commonly deceive themselves in respect of the love which they imagine others bear them, nor can ever be sure of it until they have put it to the proof. But to make proof of it in a matter like this is very perilous; and even if you have proved it already, and found it true in some other dangerous trial, you cannot assume that there will be the same fidelity here, since this far transcends every other kind of danger. Again, if you gauge a man’s fidelity by his discontent with the prince, you may easily deceive yourself; for so soon as you have taken this discontented man into your confidence, you have supplied him with the means whereby he may become contented; so that either his hatred of the prince must be great indeed, or your influence over him extraordinary, if it keep him faithful. Hence it comes that so many conspiracies have been discovered and crushed in their earliest stage, and that when the secret is preserved among many accomplices for any length of time, it is looked on as a miracle; as in the case of the conspiracy of Piso against Nero, and, in our own days, in that of the Pazzi against Lorenzo and Giuliano de’ Medici; which last, though more than fifty persons were privy to it, was not discovered until it came to be carried out. Conspiracies are disclosed through the imprudence of a conspirator when he talks so indiscreetly that some servant, or other person not in the plot, overhears him; as happened with the sons of Brutus, who, when treating with the envoys of Tarquin, were overheard by a slave, who became their accuser; or else through your own weakness in imparting your secret to some woman or boy whom you love, or to some other such light person; as when Dymnus, who was one of those who conspired with Philotas against Alexander the Great, revealed the plot to Nicomachus, a youth whom he loved, who at once told Cebalinus, and Cebalinus the king.
