There are conspiracies. Many learned of Catiline, the ideal type of a conspirator, in Latin lessons. But even the memory of Richard Nixon in the Watergate affair suffices. The secret agreements by the powerful in back rooms, the hidden workings of the intelligence services, and all forms of secret diplomacy stir in us the suspicion of conspiracy.
As a general rule, we only have knowledge of failed conspiracies. And their failure, as once noted by Machiavelli in his Discorsi, is highly probable, for when more than a handful of people conspire to commit a crime, the danger posed by whistleblowers grows exponentially. Yet it does not naturally follow that conspiracies cannot succeed. We just know nothing about them. The perfect conspiracy remains just as invisible as the perfect murder.
