Republic IV. INTRODUCTION. In attempting to prove that the soul has three separate faculties, Plato takes occasion to discuss what makes difference of faculties. And the criterion which he proposes is difference in the working of the faculties. The same faculty cannot produce contradictory effects. But the path of early reasoners is beset by thorny entanglements, and he will not proceed a step without first clearing the ground. This leads him into a tiresome digression, which is intended to explain the nature of contradiction. First, the contradiction must be at the same time and in the same relation. Secondly, no extraneous word must be introduced into either of the terms in which the contradictory proposition is expressed: for example, thirst is of drink, not of warm drink. He implies, what he does not say, that if, by the advice of reason, or by the impulse of anger, a man is restrained from drinking, this proves that thirst, or desire under which thirst is included, is distinct from anger and reason. But suppose that we allow the term ‘thirst’ or ‘desire’ to be modified, and say an ‘angry thirst,’ or a ‘revengeful desire,’ then the two spheres of desire and anger overlap and become confused. This case therefore has to be excluded. And still there remains an exception to the rule in the use of the term ‘good,’ which is always implied in the object of desire. These are the discussions of an age before logic; and any one who is wearied by them should remember that they are necessary to the clearing up of ideas in the first development of the human faculties.
The psychology of Plato extends no further than the division of the soul into the rational, irascible, and concupiscent elements, which, as far as we know, was first made by him, and has been retained by Aristotle and succeeding ethical writers. The chief difficulty in this early analysis of the mind is to define exactly the place of the irascible faculty (θυμός), which may be variously described under the terms righteous indignation, spirit, passion. It is the foundation of courage, which includes in Plato lxviii moral courage, the courage of enduring pain, and of surmounting intellectual difficulties, as well as of meeting dangers in war. Though irrational, it inclines to side with the rational: it cannot be aroused by punishment when justly inflicted: it sometimes takes the form of an enthusiasm which sustains a man in the performance of great actions. It is the ‘lion heart’ with which the reason makes a treaty (ix. 589 B). On the other hand it is negative rather than positive; it is indignant at wrong or falsehood, but does not, like Love in the Symposium and Phaedrus, aspire to the vision of Truth or Good. It is the peremptory military spirit which prevails in the government of honour. It differs from anger (ὀργή), this latter term having no accessory notion of righteous indignation. Although Aristotle has retained the word, yet we may observe that ‘passion’ (θυμός) has with him lost its affinity to the rational and has become indistinguishable from ‘anger’ (ὀργή). And to this vernacular use Plato himself in the Laws seems to revert (ix. 836 B), though not always (v. 731 A). By modern philosophy too, as well as in our ordinary conversation, the words anger or passion are employed almost exclusively in a bad sense; there is no connotation of a just or reasonable cause by which they are aroused. The feeling of ‘righteous indignation’ is too partial and accidental to admit of our regarding it as a separate virtue or habit. We are tempted also to doubt whether Plato is right in supposing that an offender, however justly condemned, could be expected to acknowledge the justice of his sentence; this is the spirit of a philosopher or martyr rather than of a criminal.
We may observe (p. 444 D, E) how nearly Plato approaches Aristotle’s famous thesis, that ‘good actions produce good habits.’ The words ‘as healthy practices (ἐπιτηδεύματα) produce health, so do just practices produce justice,’ have a sound very like the Nicomachean Ethics. But we note also that an incidental remark in Plato has become a far-reaching principle in Aristotle, and an inseparable part of a great Ethical system.
There is a difficulty in understanding what Plato meant by ‘the longer way’ (435 D; cp. infra, vi. 504): he seems to intimate some metaphysic of the future which will not be satisfied with arguing from the principle of contradiction. In the sixth and seventh books (compare Sophist and Parmenides) he has given lxix us a sketch of such a metaphysic; but when Glaucon asks for the final revelation of the idea of good, he is put off with the declaration that he has not yet studied the preliminary sciences. How he would have filled up the sketch, or argued about such questions from a higher point of view, we can only conjecture. Perhaps he hoped to find some a priori method of developing the parts out of the whole; or he might have asked which of the ideas contains the other ideas, and possibly have stumbled on the Hegelian identity of the ‘ego’ and the ‘universal.’ Or he may have imagined that ideas might be constructed in some manner analogous to the construction of figures and numbers in the mathematical sciences. The most certain and necessary truth was to Plato the universal; and to this he was always seeking to refer all knowledge or opinion, just as in modern times we seek to rest them on the opposite pole of induction and experience. The aspirations of metaphysicians have always tended to pass beyond the limits of human thought and language: they seem to have reached a height at which they are ‘moving about in worlds unrealized,’ and their conceptions, although profoundly affecting their own minds, become invisible or unintelligible to others. We are not therefore surprized to find that Plato himself has nowhere clearly explained his doctrine of ideas; or that his school in a later generation, like his contemporaries Glaucon and Adeimantus, were unable to follow him in this region of speculation. In the Sophist, where he is refuting the scepticism which maintained either that there was no such thing as predication, or that all might be predicated of all, he arrives at the conclusion that some ideas combine with some, but not all with all. But he makes only one or two steps forward on this path; he nowhere attains to any connected system of ideas, or even to a knowledge of the most elementary relations of the sciences to one another (see infra).
Republic V. ANALYSIS. BOOK V. 449I was going to enumerate the four forms of vice or decline in states, when Polemarchus—he was sitting a little farther from me than Adeimantus—taking him by the coat and leaning towards him, said something in an undertone, of which I only caught the words, ‘Shall we let him off?’ ‘Certainly not,’ said Adeimantus, raising his voice. Whom, I said, are you lxx not going to let off? ‘You,’ he said. Why? ‘Because we think that you are not dealing fairly with us in omitting women and children, of whom you have slily disposed under the general formula that friends have all things in common.’ And was I not right? ‘Yes,’ he replied, ‘but there are many sorts of communism or community, and we want to know which of them is right. The company, as you have just heard, are resolved to have a further explanation.’ 450Thrasymachus said, ‘Do you think that we have come hither to dig for gold, or to hear you discourse?’ Yes, I said; but the discourse should be of a reasonable length. Glaucon added, ‘Yes, Socrates, and there is reason in spending the whole of life in such discussions; but pray, without more ado, tell us how this community is to be carried out, and how the interval between birth and education is to be filled up.’ Well, I said, the subject has several difficulties—What is possible? is the first question. What is desirable? is the second. ‘Fear not,’ he replied, ‘for you are speaking among friends.’ That, I replied, is a sorry consolation; I shall destroy my friends as well as myself. 451Not that I mind a little innocent laughter; but he who kills the truth is a murderer. ‘Then,’ said Glaucon, laughing, ‘in case you should murder us we will acquit you beforehand, and you shall be held free from the guilt of deceiving us.’
Socrates proceeds:—The guardians of our state are to be watch-dogs, as we have already said. Now dogs are not divided into hes and shes—we do not take the masculine gender out to hunt and leave the females at home to look after their puppies. They have the same employments—the only difference between them is that the one sex is stronger and the other weaker. But if women are to have the same employments as men, they must have the same education—they must be taught
