The Republic. Plato Читать онлайн книгу.
moral nature of man, the still more universal conception of the good in the second education and in the sphere of speculative knowledge seems to succeed. Both might be equally described by the terms 'law,' 'order,' 'harmony;' but while the idea of good embraces 'all time and all existence,' the conception of justice is not extended beyond man.
… Socrates is now going to identify the individual and the State. But first he must prove that there are three parts of the individual soul. His argument is as follows:—Quantity makes no difference in quality. The word 'just,' whether applied to the individual or to the State, has the same meaning. And the term 'justice' implied that the same three principles in the State and in the individual were doing their own business. But are they really three or one? The question is difficult, and one which can hardly be solved by the methods which we are now using; but the truer and longer way would take up too much of our time. 'The shorter will satisfy me.' Well then, you would admit that the qualities of states mean the qualities of the individuals who compose them? The Scythians and Thracians are passionate, our own race intellectual, and the Egyptians and Phoenicians covetous, because the individual members of each have such and such a character; the difficulty is to determine whether the several principles are one or three; whether, that is to say, we reason with one part of our nature, desire with another, are angry with another, or whether the whole soul comes into play in each sort of action. This enquiry, however, requires a very exact definition of terms. The same thing in the same relation cannot be affected in two opposite ways. But there is no impossibility in a man standing still, yet moving his arms, or in a top which is fixed on one spot going round upon its axis. There is no necessity to mention all the possible exceptions; let us provisionally assume that opposites cannot do or be or suffer opposites in the same relation. And to the class of opposites belong assent and dissent, desire and avoidance. And one form of desire is thirst and hunger: and here arises a new point—thirst is thirst of drink, hunger is hunger of food; not of warm drink or of a particular kind of food, with the single exception of course that the very fact of our desiring anything implies that it is good. When relative terms have no attributes, their correlatives have no attributes; when they have attributes, their correlatives also have them. For example, the term 'greater' is simply relative to 'less,' and knowledge refers to a subject of knowledge. But on the other hand, a particular knowledge is of a particular subject. Again, every science has a distinct character, which is defined by an object; medicine, for example, is the science of health, although not to be confounded with health. Having cleared our ideas thus far, let us return to the original instance of thirst, which has a definite object—drink. Now the thirsty soul may feel two distinct impulses; the animal one saying 'Drink;' the rational one, which says 'Do not drink.' The two impulses are contradictory; and therefore we may assume that they spring from distinct principles in the soul. But is passion a third principle, or akin to desire? There is a story of a certain Leontius which throws some light on this question. He was coming up from the Piraeus outside the north wall, and he passed a spot where there were dead bodies lying by the executioner. He felt a longing desire to see them and also an abhorrence of them; at first he turned away and shut his eyes, then, suddenly tearing them open, he said—'Take your fill, ye wretches, of the fair sight.' Now is there not here a third principle which is often found to come to the assistance of reason against desire, but never of desire against reason? This is passion or spirit, of the separate existence of which we may further convince ourselves by putting the following case:—When a man suffers justly, if he be of a generous nature he is not indignant at the hardships which he undergoes: but when he suffers unjustly, his indignation is his great support; hunger and thirst cannot tame him; the spirit within him must do or die, until the voice of the shepherd, that is, of reason, bidding his dog bark no more, is heard within. This shows that passion is the ally of reason. Is passion then the same with reason? No, for the former exists in children and brutes; and Homer affords a proof of the distinction between them when he says, 'He smote his breast, and thus rebuked his soul.'
And now, at last, we have reached firm ground, and are able to infer that the virtues of the State and of the individual are the same. For wisdom and courage and justice in the State are severally the wisdom and courage and justice in the individuals who form the State. Each of the three classes will do the work of its own class in the State, and each part in the individual soul; reason, the superior, and passion, the inferior, will be harmonized by the influence of music and gymnastic. The counsellor and the warrior, the head and the arm, will act together in the town of Mansoul, and keep the desires in proper subjection. The courage of the warrior is that quality which preserves a right opinion about dangers in spite of pleasures and pains. The wisdom of the counsellor is that small part of the soul which has authority and reason. The virtue of temperance is the friendship of the ruling and the subject principles, both in the State and in the individual. Of justice we have already spoken; and the notion already given of it may be confirmed by common instances. Will the just state or the just individual steal, lie, commit adultery, or be guilty of impiety to gods and men? 'No.' And is not the reason of this that the several principles, whether in the state or in the individual, do their own business? And justice is the quality which makes just men and just states. Moreover, our old division of labour, which required that there should be one man for one use, was a dream or anticipation of what was to follow; and that dream has now been realized in justice, which begins by binding together the three chords of the soul, and then acts harmoniously in every relation of life. And injustice, which is the insubordination and disobedience of the inferior elements in the soul, is the opposite of justice, and is inharmonious and unnatural, being to the soul what disease is to the body; for in the soul as well as in the body, good or bad actions produce good or bad habits. And virtue is the health and beauty and well-being of the soul, and vice is the disease and weakness and deformity of the soul.
Again the old question returns upon us: Is justice or injustice the more profitable? The question has become ridiculous. For injustice, like mortal disease, makes life not worth having. Come up with me to the hill which overhangs the city and look down upon the single form of virtue, and the infinite forms of vice, among which are four special ones, characteristic both of states and of individuals. And the state which corresponds to the single form of virtue is that which we have been describing, wherein reason rules under one of two names—monarchy and aristocracy. Thus there are five forms in all, both of states and of souls …
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 (Greek), which may be variously described under the terms righteous indignation, spirit, passion. It is the foundation of courage, which includes in Plato 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
