"Socrates (and so Plato) makes it quite clear that the rule of wisdom is tyrannical, and that it cannot tolerate words or deeds, laws or traditional institutions, and certainly political theories that impinge upon its rule. In this sense, modern enemies of Plato's political thought, of whom the most prominent in our time is no doubt Karl Popper, are correct in their objections, although they are ingenuous or let us say insufficiently rigorous in their consideration of the political consequences of theoretical truth. In Popper's case, this is probably due to his conviction that we can establish the falsehood of a proposition but not its truth. This conviction may well be more compatible with democracy in the modern sense of the term than the conviction that genuine philosophers know the truth. The argument of the Republic on the other hand is that, if we did know the truth, we would be led to support a city very much like the one constructed in the Republic under the leadership of Socrates."
