The disappointment of Glaucon at the 'city of pigs,' the ludicrous description of the ministers of luxury in the more refined {xxxvii} State, and the afterthought of the necessity of doctors, the illustration of the nature of the guardian taken from the dog, the desirableness of offering some almost unprocurable victim when impure mysteries are to be celebrated, the behaviour of Zeus to his father and of Hephaestus to his mother, are touches of humour which have also a serious meaning. In speaking of education Plato rather startles us by affirming that a child must be trained in falsehood first and in truth afterwards. Yet this is not very different from saying that children must be taught through the medium of imagination as well as reason; that their minds can only develope gradually, and that there is much which they must learn without understanding (cp. iii. 402 A). This is also the substance of Plato's view, though he must be acknowledged to have drawn the line somewhat differently from modern ethical writers, respecting truth and falsehood. To us, economies or accommodations would not be allowable unless they were required by the human faculties or necessary for the communication of knowledge to the simple and ignorant. We should insist that the word was inseparable from the intention, and that we must not be 'falsely true,' i.e. speak or act falsely in support of what was right or true. But Plato would limit the use of fictions only by requiring that they should have a good moral effect, and that such a dangerous weapon as falsehood should be employed by the rulers alone and for great objects.
