Now in such a city, in the polis êdê tryphôsa,+ there will be an increase of population:-- kai hê chôra pou hê tote hikanê smikra ex hikanês estai.+ And in an age which perhaps had the military spirit in excess Plato's thoughts pass on immediately to wars of aggression:-- oukoun tês tôn plêsion chôras hêmin apotmêteon?+ We must take something, if we can, from Megara or from Sparta; which doubtless in its turn would do the same by us. As a measure of relief however that was not necessarily the next step. The needs of an out-pushing population might have suggested to Plato what is perhaps the most brilliant and animating episode in the entire history of Greece, its early colonisation, with all the bright stories, full of the piety, the generosity of a youthful people, that had gathered about it. No, the next step in social development was not necessarily going to war. In either case however, aggressive action against our neighbours, or defence of our distant brethren beyond the seas [247] at Cyrene or Syracuse against rival adventurers, we shall require a new class of persons, men of the sword, to fight for us if need be. Ah! You hear the notes of the trumpet, and therewith already the stir of an enlarging human life, its passions, its manifold interests. Phylakes or epikouroi,+ watchmen or auxiliaries, our new servants comprehend at first our masters to be, whom a further act of differentiation will distinguish as philosophers and kings from the strictly military order. Plato nevertheless in his search for the true idea of Justice, of rightness in things, may be said now to have seen land. Organic relationship is come into the rude social elements and made of them a body, a society. Rudimentary though it may still be, the definition of Justice, as also of Injustice, is now applicable to its processes. There is a music in the affairs of men, in which one may take one's due part, which one may spoil. Criticising mythology Plato speaks of certain fables, to be made by those who are apt at such things, under proper spiritual authority, so to term it, hôs en pharmakou eidei ta pseudê ta en deonti genomena,+ medicinable lies or fictions, with a provisional or economised truth in them, set forth under such terms as simple souls could best receive. Just here, at the end of the third book of The Republic he introduces such a fable: phoinikikon pseudos,+ he calls it, a miner's story, about copper and silver and gold, such as may really [248] have been current among the primitive inhabitants of the island from which metal and the art of working it had been introduced into Greece.--
