The irony is, that to Plato, tyranny is the absolute worst form of government. Yet his ideal form of government, aristocracy (as it is translated in my version; the rule of specially trained guardians) is no more palatable to us today, being very much like a tolitalitarian communistic government, with everything held in common, wives, children, property, and state run censorship, among other things. I think he would have been astonished at Stalin (and other Communist tyrants) who seems to have combined the two extremes.
