" Pericles’ speech is not only a programme. It is also a defence, and perhaps even an attack. It reads, as I have already hinted, like a direct attack on Plato. I do not doubt that it was directed, not only against the arrested tribalism of Sparta, but also against the totalitarian ring or ‘link’ at home; against the movement for the paternal state, the Athenian ‘Society of the Friends of Laconia’ (as Th. Gomperz called them in 190232). The speech is the earliest33 and at the same time perhaps the strongest statement ever made in opposition to this kind of movement. Its importance was felt by Plato, who caricatured Pericles’ oration half a century later in the passages of the Republic34 in which he attacks democracy, as well as in that undisguised parody, the dialogue called Menexenus or the Funeral Oration35. But the Friends of Laconia whom Pericles attacked retaliated long before Plato. Only five or six years after Pericles’ oration, a pamphlet on the Constitution of Athens36 was published by an unknown author (possibly Critias), now usually called the ‘Old Oligarch’. This ingenious pamphlet, the oldest extant treatise on political theory, is, at the same time, perhaps the oldest monument of the desertion of mankind by its intellectual leaders. It is a ruthless attack upon Athens, written no doubt by one of her best brains. Its central idea, an idea which became an article of faith with Thucydides and Plato, is the close connection between naval imperialism and democracy. And it tries to show that there can be no compromise in a conflict between two worlds37, the worlds of democracy and of oligarchy; that only the use of ruthless violence, of total measures, including the intervention of allies from outside (the Spartans), can put an end to the unholy rule of freedom. This remarkable pamphlet was to become the first of a practically infinite sequence of works on political philosophy which were to repeat more or less, openly or covertly, the same theme down to our own day. Unwilling and unable to help mankind along their difficult path into an unknown future which they have to create for themselves, some of the ‘educated’ tried to make them turn back into the past. Incapable of leading a new way, they could only make themselves leaders of the perennial revolt against freedom. It became the more necessary for them to assert their superiority by fighting against equality as they were (using Socratic language) misanthropists and misologists—incapable of that simple and ordinary generosity which inspires faith in men, and faith in human reason and freedom. Harsh as this judgement may sound, it is just, I fear, if it is applied to those intellectual leaders of the revolt against freedom who came after the Great Generation, and especially after Socrates. We can now try to see them against the background of our historical interpretation. "
