Plato, like other philosophers, is thus led on to the conclusion, that if ‘the ways of God’ to man are to be ‘justified,’ the hopes of another life must be included. If the question could have been put to him, whether a man dying in torments was happy still, even if, as he suggests in the Apology (40 C), ‘death be only a long sleep,’ we can hardly tell what would have been his answer. There have been a few, who, quite independently of rewards and punishments or of posthumous reputation, or any other influence of public opinion, have been willing to sacrifice their lives for the good of others. It is difficult to say how far in such cases an unconscious hope of a future life, or a general faith in the victory of good in the world, may have supported the sufferers. But this extreme idealism is not in accordance with the spirit of Plato. He supposes a day of retribution, in which the good are to be rewarded and the wicked punished (522 E). Though, as he says in the Phaedo, no man of sense will maintain that the details of the stories about another world are true, he will insist that something of the kind is true, and will frame his life with a view to this unknown future. Even in the Republic he introduces a future life as an afterthought, when the superior happiness of the just has been established on what is thought to be an immutable foundation. At the same time he makes a point of determining his main thesis independently of remoter consequences (x. 612 A). (3) Plato’s theory of punishment is partly vindictive, partly corrective. In the Gorgias, as well as in the Phaedo and Republic, a few great criminals, chiefly tyrants, are reserved as examples. But most men have never had the opportunity of attaining this pre-eminence of evil. They are not incurable, and their punishment is intended for their improvement. They are to suffer because they have sinned; like sick men, they must go to the physician and be healed. On this representation of Plato’s the criticism has been made, that the analogy of disease and injustice is partial only, and that suffering, instead of improving men, may have just the opposite effect. Like the general analogy of the arts and the virtues, the analogy of disease and injustice, or of medicine and justice, is certainly imperfect. But ideas must be given through something; the nature of the mind which is unseen can only be represented under figures derived from visible objects. If these figures are suggestive of some new aspect under which the mind may be considered, we cannot find fault with them for not exactly coinciding with the ideas represented. They partake of the imperfect nature of language, and must not be construed in too strict a manner. That Plato sometimes reasons from them as if they were not figures but realities, is due to the defective logical analysis of his age. [Sidenote: _Plato’s theory of punishment._]
