“Modern man, seeking a middle position in the evaluation of sense impression and thought, can, following Plato, interpret the process of understanding nature as a correspondence, that is, a coming into congruence of pre-existing images of the human psyche with external objects and their behaviour. Modern man, of course, unlike Plato, looks on the pre-existent original images also as not invariable, but as relative to the development of a conscious point of view, so that the word "dialectic" which Plato is fond of using may be applied to the process of development of human knowledge.”

“He maintains in effect that the gulf separating Plato from the average man is greater than the cleft between the average man and a chimpanzee.”

Walter Kaufmann book Nietzsche: Philosopher, Psychologist, Antichrist

Source: Nietzsche: Philosopher, Psychologist, Antichrist (1951), p. 151
Context: There is thus a certain plausibility to Nietzsche's doctrine, though it is dynamite. He maintains in effect that the gulf separating Plato from the average man is greater than the cleft between the average man and a chimpanzee.

“Plato was accused by some of his twentieth-century critics of racism, totalitarianism, fascism, and other political crimes with a very contemporary flavor. These accusations are too anachronistic to be taken seriously; whatever explains Hitler and Mussolini, it is not the dialogues of Plato. The more plausible complaint is that Plato does not take seriously the inescapability of politics in some form. Plato’s metaphysics is fascinating; so is his conviction that the just man does better than the unjust man, no matter what earthly fate befalls him. His political thinking often amounts to an injunction to abolish the conflicts that politics exists to resolve and fantasies about how it might be done.”

“Let us endeavour for a moment to disconnect our thinking selves from the mask of humanity; let us imagine ourselves scientific Saturnians, if you will, fairly acquainted with such animals as now inhabit the Earth, and employed in discussing the relations they bear to a new and singular 'erect and featherless biped,' which some enterprising traveller, overcoming the difficulties of space and gravitation, has brought from that distant planet for our inspection, well preserved, may be, in a cask of rum.”

“Puppets really are the origin of theater. Even the shadow on the wall of Plato's cave was a puppet. The very first actor was some kind of hand creating some kind of animal.”

Julie Taymor (1952) American film and theatre director

Academy of Achievement interview (2006)
Context: You know, we still hear the word "puppet" and we get this nauseating image of some kind of Muppet or something. Puppets really are the origin of theater. Even the shadow on the wall of Plato's cave was a puppet. The very first actor was some kind of hand creating some kind of animal.

“Socrates having heard Plato read the Lysis, said, "O Hercules! what a number of lies the young man has told about me." For he had set down a great many things as sayings of Socrates which he never said.”

Socrates (-470–-399 BC) classical Greek Athenian philosopher

Diogenes Laertius

“The results of Socrates' martyrdom and Plato's unexcelled prose that followed are nothing less than the whole world of Western man as we know it. If the idea of truth had been allowed to perish unrediscovered by the Renaissance it's unlikely that we would be much beyond the level of prehistoric man today. The ideas of science and technology and other systematically organized efforts of man are dead-centered on it. It is the nucleus of it all.”
