In the early days of his tyranny he smiles and beams upon everybody; he is not a ‘dominus,’ no, not he: he has only come to put an end to debt and the monopoly of land. Having got rid of foreign enemies, he makes himself necessary to the State by always going to war. He is thus enabled to depress the poor by heavy taxes, and so keep them at work; and he can get rid of bolder spirits by handing them over to the enemy. Then comes unpopularity; some of his old associates have the courage to oppose him. The consequence is, that he has to make a purgation of the State; but, unlike the physician who purges away the bad, he must get rid of the high-spirited, the wise and the wealthy; for he has no choice between death and a life of shame and dishonour. And the more hated he is, the more he will require trusty guards; but how will he obtain them? ‘They will come flocking like birds—for pay.’Will he not rather obtain them on the spot? He will take the slaves from their owners and make them his body-guard; these are his trusted friends, who admire and look up to him. Are not the tragic poets wise who magnify and exalt the tyrant, and say that he is wise by association with the wise? And are not their praises of tyranny alone a sufficient reason why we should exclude them from our State? They may go to other cities, and gather the mob about them with fine words, and change commonwealths into tyrannies and democracies, receiving honours and rewards for their services; but the higher they and their friends ascend constitution hill, the more their honour will fail and become ‘too asthmatic to mount.’ To return to the tyrant—How will he support that rare army of his? First, by robbing the temples of their treasures, which will enable him to lighten the taxes; then he will take all his father’s property, and spend it on his companions, male or female. Now his father is the demus, and if the demus gets angry, and says that a great hulking son ought not to be a burden on his parents, and bids him and his riotous crew begone, then will the parent know what a monster he has been nurturing, and that the son whom he would fain expel is too strong for him. ‘You do not mean to say that he will beat his father?’ Yes, he will, after having taken away his arms. ‘Then he is a parricide and a cruel, unnatural son.’ And the people have jumped from the fear of slavery into slavery, out of the smoke into the fire. Thus liberty, when out of all order and reason, passes into the worst form of servitude...
In the previous books Plato has described the ideal State; now he returns to the perverted or declining forms, on which he had lightly touched at the end of Book IV. These he describes in a succession of parallels between the individuals and the States, tracing the origin of either in the State or individual which has preceded them. He begins by asking the point at which he digressed; and is thus led shortly to recapitulate the substance of the three former books, which also contain a parallel of the philosopher and the State.
Of the first decline he gives no intelligible account; he would not have liked to admit the most probable causes of the fall of his ideal State, which to us would appear to be the impracticability of communism or the natural antagonism of the ruling and subject classes. He throws a veil of mystery over the origin of the decline, which he attributes to ignorance of the law of population. Of this law the famous geometrical figure or number is the expression. Like the ancients in general, he had no idea of the gradual perfectibility of man or of the education of the human race. His ideal was not to be attained in the course of ages, but was to spring in full armour from the head of the legislator. When good laws had been given, he thought only of the manner in which they were likely to be corrupted, or of how they might be filled up in detail or restored in accordance with their original spirit. He appears not to have reflected upon the full meaning of his own words, ‘In the brief space of human life, nothing great can be accomplished’; or again, as he afterwards says in the Laws, ‘Infinite time is the maker of cities.’The order of constitutions which is adopted by him represents an order of thought rather than a succession of time, and may be considered as the first attempt to frame a philosophy of history.
The first of these declining States is timocracy, or the government of soldiers and lovers of honour, which answers to the Spartan State; this is a government of force, in which education is not inspired by the Muses, but imposed by the law, and in which all the finer elements of organization have disappeared. The philosopher himself has lost the love of truth, and the soldier, who is of a simpler and honester nature, rules in his stead. The individual who answers to timocracy has some noticeable qualities. He is described as ill educated, but, like the Spartan, a lover of literature; and although he is a harsh master to his servants he has no natural superiority over them. His character is based upon a reaction against the circumstances of his father, who in a troubled city has retired from politics; and his mother, who is dissatisfied at her own position, is always urging him towards the life of political ambition. Such a character may have had this origin, and indeed Livy attributes the Licinian laws to a feminine jealousy of a similar kind. But there is obviously no connection between the manner in which the timocratic State springs out of the ideal, and the mere accident by which the timocratic man is the son of a retired statesman.
The two next stages in the decline of constitutions have even less historical foundation. For there is no trace in Greek history of a polity like the Spartan or Cretan passing into an oligarchy of wealth, or of the oligarchy of wealth passing into a democracy. The order of history appears to be different; first, in the Homeric times there is the royal or patriarchal form of government, which a century or two later was succeeded by an oligarchy of birth rather than of wealth, and in which wealth was only the accident of the hereditary possession of land and power. Sometimes this oligarchical government gave way to a government based upon a qualification of property, which, according to Aristotle’s mode of using words, would have been called a timocracy; and this in some cities, as at Athens, became the conducting medium to democracy. But such was not the necessary order of succession in States; nor, indeed, can any order be discerned in the endless fluctuation of Greek history (like the tides in the Euripus), except, perhaps, in the almost uniform tendency from monarchy to aristocracy in the earliest times. At first sight there appears to be a similar inversion in the last step of the Platonic succession; for tyranny, instead of being the natural end of democracy, in early Greek history appears rather as a stage leading to democracy; the reign of Peisistratus and his sons is an episode which comes between the legislation of Solon and the constitution of Cleisthenes; and some secret cause common to them all seems to have led the greater part of Hellas at her first appearance in the dawn of history, e.g. Athens, Argos, Corinth, Sicyon, and nearly every State with the exception of Sparta, through a similar stage of tyranny which ended either in oligarchy or democracy. But then we must remember that Plato is describing rather the contemporary governments of the Sicilian States, which alternated between democracy and tyranny, than the ancient history of Athens or Corinth.
The portrait of the tyrant himself is just such as the later Greek delighted to draw of Phalaris and Dionysius, in which, as in the lives of mediaeval saints or mythic heroes, the conduct and actions of one were attributed to another in order to fill up the outline. There was no enormity which the Greek was not today to believe of them; the tyrant was the negation of government and law; his assassination was glorious; there was no crime, however unnatural, which might not with probability be attributed to him. In this, Plato was only following the common thought of his countrymen, which he embellished and exaggerated with all the power of his genius. There is no need to suppose that he drew from life; or that his knowledge of tyrants is derived from a personal acquaintance with Dionysius. The manner in which he speaks of them would rather tend to render doubtful his ever having ‘consorted’ with them, or entertained the schemes, which are attributed to him in the Epistles, of regenerating Sicily by their help.
Plato in a hyperbolical and serio-comic vein exaggerates the follies of democracy which he also sees reflected in social life. To him democracy is a state of individualism or dissolution; in which every one is doing what is right in his own eyes. Of a people animated by a common spirit of liberty, rising as one man to repel the Persian host, which is the leading idea of democracy in Herodotus and Thucydides, he never seems to think. But if he is not a believer in liberty, still less is he a lover of tyranny. His deeper and more serious condemnation is reserved for the tyrant, who is the ideal of wickedness and also of weakness, and who in his utter helplessness and suspiciousness is leading an almost impossible existence, without that remnant of good which, in Plato’s opinion, was required to give power to evil (Book I). This ideal of wickedness living in helpless misery, is the reverse of that other portrait of perfect injustice ruling in happiness and splendour, which first of all Thrasymachus, and afterwards the sons of Ariston had drawn, and is also the reverse of the king whose rule of life is the good of his subjects.
Each of these governments and individuals has a corresponding ethical gradation: the ideal State is under the rule of reason, not extinguishing but harmonizing the passions, and training them in virtue; in the timocracy and the timocratic man the constitution, whether of the State or of the individual, is based, first, upon courage, and secondly, upon the love of honour; this latter virtue, which is hardly to be esteemed a virtue, has superseded all the rest. In the second stage of decline the virtues have altogether disappeared, and the love of gain has succeeded to them; in the third stage, or democracy, the various passions are allowed to have free play, and the virtues and vices are impartially cultivated. But this freedom, which leads to many curious extravagances of character, is in reality only a state of weakness and dissipation. At last, one monster passion takes possession of the whole nature of man—this is tyranny. In all of them excess—the excess first of wealth and then of freedom, is the element of decay.
The eighth book of the Republic abounds in pictures of life and fanciful allusions; the use of metaphorical language is carried to a greater extent than anywhere else in Plato. We may remark,
(1), the description of the two nations in one, which become more and more divided in the Greek Republics, as in feudal times, and perhaps also in our own;
(2), the notion of democracy expressed in a sort of Pythagorean formula as equality among unequals;
(3), the free and easy ways of men and animals, which are characteristic of liberty, as foreign mercenaries and universal mistrust are of the tyrant;
(4), the proposal that mere debts should not be recoverable by law is a speculation which has often been entertained by reformers of the law in modern times, and is in harmony with the tendencies of modern legislation. Debt and land were the two great difficulties of the ancient lawgiver: in modern times we may be said to have almost, if not quite, solved the first of these difficulties, but hardly the second.
Still more remarkable are the corresponding portraits of individuals: there is the family picture of the father and mother and the old servant of the timocratical man, and the outward respectability and inherent meanness of the oligarchical; the uncontrolled licence and freedom of the democrat, in which the young Alcibiades seems to be depicted, doing right or wrong as he pleases, and who at last, like the prodigal, goes into a far country (note here the play of language by which the democratic man is himself represented under the image of a State having a citadel and receiving embassies); and there is the wild-beast nature, which breaks loose in his successor. The hit about the tyrant being a parricide; the representation of the tyrant’s life as an obscene dream; the rhetorical surprise of a more miserable than the most miserable of men in Book IX; the hint to the poets that if they are the friends of tyrants there is no place for them in a constitutional State, and that they are too clever not to see the propriety of their own expulsion; the continuous image of the drones who are of two kinds, swelling at last into the monster drone having wings (Book IX),—are among Plato’s happiest touches.
There remains to be considered the great difficulty of this book of the Republic, the so-called number of the State. This is a puzzle almost as great as the Number of the Beast in the Book of Revelation, and though apparently known to Aristotle, is referred to by Cicero as a proverb of obscurity (Ep. ad Att.). And some have imagined that there is no answer to the puzzle, and that Plato has been practising upon his readers. But such a deception as this is inconsistent with the manner in which Aristotle speaks of the number (Pol.), and would have been ridiculous to any reader of the Republic who was acquainted with Greek mathematics. As little reason is there for supposing that Plato intentionally used obscure expressions; the obscurity arises from our want of familiarity with the subject. On the other hand, Plato himself indicates that he is not altogether serious, and in describing his number as a solemn jest of the Muses, he appears to imply some degree of satire on the symbolical use of number. (Compare Cratylus; Protag.)
Our hope of understanding the passage depends principally on an accurate study of the words themselves; on which a faint light is thrown by the parallel passage in the ninth book. Another help is the allusion in Aristotle, who makes the important remark that the latter part of the passage (Greek) describes a solid figure. (Pol.—’He only says that nothing is abiding, but that all things change in a certain cycle; and that the origin of the change is a base of numbers which are in the ratio of 4:3; and this when combined with a figure of five gives two harmonies; he means when the number of this figure becomes solid.’) Some further clue may be gathered from the appearance of the Pythagorean triangle, which is denoted by the numbers 3, 4, 5, and in which, as in every right-angled triangle, the squares of the two lesser sides equal the square of the hypotenuse (9 + 16 = 25).
Plato begins by speaking of a perfect or cyclical number (Tim.), i.e. a number in which the sum of the divisors equals the whole; this is the divine or perfect number in which all lesser cycles or revolutions are complete. He also speaks of a human or imperfect number, having four terms and three intervals of numbers which are related to one another in certain proportions; these he converts into figures, and finds in them when they have been raised to the third power certain elements of number, which give two ‘harmonies,’ the one square, the other oblong; but he does not say that the square number answers to the divine, or the oblong number to the human cycle; nor is any intimation given that the first or divine number represents the period of the world, the second the period of the state, or of the human race as Zeller supposes; nor is the divine number afterwards mentioned (Arist.). The second is the number of generations or births, and presides over them in the same mysterious manner in which the stars preside over them, or in which, according to the Pythagoreans, opportunity, justice, marriage, are represented by some number or figure. This is probably the number 216.
The explanation given in the text supposes the two harmonies to make up the number 8000. This explanation derives a certain plausibility from the circumstance that 8000 is the ancient number of the Spartan citizens (Herod.), and would be what Plato might have called ‘a number which nearly concerns the population of a city’; the mysterious disappearance of the Spartan population may possibly have suggested to him the first cause of his decline of States. The lesser or square ‘harmony,’ of 400, might be a symbol of the guardians,—the larger or oblong ‘harmony,’ of the people, and the numbers 3, 4, 5 might refer respectively to the three orders in the State or parts of the soul, the four virtues, the five forms of government. The harmony of the musical scale, which is elsewhere used as a symbol of the harmony of the state, is also indicated. For the numbers 3, 4, 5, which represent the sides of the Pythagorean triangle, also denote the intervals of the scale.
The terms used in the statement of the problem may be explained as follows. A perfect number (Greek), as already stated, is one which is equal to the sum of its divisors. Thus 6, which is the first perfect or cyclical number, = 1 + 2 + 3. The words (Greek), ‘terms’ or ‘notes,’ and (Greek), ‘intervals,’ are applicable to music as well as to number and figure. (Greek) is the ‘base’ on which the whole calculation depends, or the ‘lowest term’ from which it can be worked out. The words (Greek) have been variously translated—’squared and cubed’ (Donaldson), ‘equalling and equalled in power’ (Weber), ‘by involution and evolution,’ i.e. by raising the power and extracting the root (as in the translation). Numbers are called ‘like and unlike’ (Greek) when the factors or the sides of the planes and cubes which they represent are or are not in the same ratio: e.g. 8 and 27 = 2 cubed and 3 cubed; and conversely. ‘Waxing’ (Greek) numbers, called also ‘increasing’ (Greek), are those which are exceeded by the sum of their divisors: e.g. 12 and 18 are less than 16 and 21. ‘Waning’ (Greek) numbers, called also ‘decreasing’ (Greek) are those which succeed the sum of their divisors: e.g. 8 and 27 exceed 7 and 13. The words translated ‘commensurable and agreeable to one another’ (Greek) seem to be different ways of describing the same relation, with more or less precision. They are equivalent to ‘expressible in terms having the same relation to one another,’ like the series 8, 12, 18, 27, each of which numbers is in the relation of (1 and 1/2) to the preceding. The ‘base,’or ‘fundamental number, which has 1/3 added to it’(1 and 1/3) = 4/3 or a musical fourth. (Greek) is a ‘proportion’ of numbers as of musical notes, applied either to the parts or factors of a single number or to the relation of one number to another. The first harmony is a ‘square’ number (Greek); the second harmony is an ‘oblong’ number (Greek), i.e. a number representing a figure of which the opposite sides only are equal. (Greek) = ‘numbers squared from’ or ‘upon diameters’; (Greek) = ‘rational,’ i.e. omitting fractions, (Greek), ‘irrational,’ i.e. including fractions; e.g. 49 is a square of the rational diameter of a figure the side of which = 5: 50, of an irrational diameter of the same. For several of the explanations here given and for a good deal besides I am indebted to an excellent article on the Platonic Number by Dr. Donaldson (Proc. of the Philol. Society).
The conclusions which he draws from these data are summed up by him as follows. Having assumed that the number of the perfect or divine cycle is the number of the world, and the number of the imperfect cycle the number of the state, he proceeds: ‘The period of the world is defined by the perfect number 6, that of the state by the cube of that number or 216, which is the product of the last pair of terms in the Platonic Tetractys (a series of seven terms, 1, 2, 3, 4, 9, 8, 27); and if we take this as the basis of our computation, we shall have two cube numbers (Greek), viz. 8 and 27; and the mean proportionals between these, viz. 12 and 18, will furnish three intervals and four terms, and these terms and intervals stand related to one another in the sesqui-altera ratio, i.e. each term is to the preceding as 3/2. Now if we remember that the number 216 = 8 x 27 = 3 cubed + 4 cubed + 5 cubed, and 3 squared + 4 squared = 5 squared, we must admit that this number implies the numbers 3, 4, 5, to which musicians attach so much importance. And if we combine the ratio 4/3 with the number 5, or multiply the ratios of the sides by the hypotenuse, we shall by first squaring and then cubing obtain two expressions, which denote the ratio of the two last pairs of terms in the Platonic Tetractys, the former multiplied by the square, the latter by the cube of the number 10, the sum of the first four digits which constitute the Platonic Tetractys.’ The two (Greek) he elsewhere explains as follows: ‘The first (Greek) is (Greek), in other words (4/3 x 5) all squared = 100 x 2 squared over 3 squared. The second (Greek), a cube of the same root, is described as 100 multiplied (alpha) by the rational diameter of 5 diminished by unity, i.e., as shown above, 48: (beta) by two incommensurable diameters, i.e. the two first irrationals, or 2 and 3: and (gamma) by the cube of 3, or 27. Thus we have (48 + 5 + 27) 100 = 1000 x 2 cubed. This second harmony is to be the cube of the number of which the former harmony is the square, and therefore must be divided by the cube of 3. In other words, the whole expression will be: (1), for the first harmony, 400/9: (2), for the second harmony, 8000/27.’
The reasons which have inclined me to agree with Dr. Donaldson and also with Schleiermacher in supposing that 216 is the Platonic number of births are: (1) that it coincides with the description of the number given in the first part of the passage (Greek...): (2) that the number 216 with its permutations would have been familiar to a Greek mathematician, though unfamiliar to us: (3) that 216 is the cube of 6, and also the sum of 3 cubed, 4 cubed, 5 cubed, the numbers 3, 4, 5 representing the Pythagorean triangle, of which the sides when squared equal the square of the hypotenuse (9 + 16 = 25): (4) that it is also the period of the Pythagorean Metempsychosis: (5) the three ultimate terms or bases (3, 4, 5) of which 216 is composed answer to the third, fourth, fifth in the musical scale: (6) that the number 216 is the product of the cubes of 2 and 3, which are the two last terms in the Platonic Tetractys: (7) that the Pythagorean triangle is said by Plutarch (de Is. et Osir.), Proclus (super prima Eucl.), and Quintilian (de Musica) to be contained in this passage, so that the tradition of the school seems to point in the same direction: (8) that the Pythagorean triangle is called also the figure of marriage (Greek).
But though agreeing with Dr. Donaldson thus far, I see no reason for supposing, as he does, that the first or perfect number is the world, the human or imperfect number the state; nor has he given any proof that the second harmony is a cube. Nor do I think that (Greek) can mean ‘two incommensurables,’ which he arbitrarily assumes to be 2 and 3, but rather, as the preceding clause implies, (Greek), i.e. two square numbers based upon irrational diameters of a figure the side of which is 5 = 50 x 2.
The greatest objection to the translation is the sense given to the words (Greek), ‘a base of three with a third added to it, multiplied by 5.’ In this somewhat forced manner Plato introduces once more the numbers of the Pythagorean triangle. But the coincidences in the numbers which follow are in favour of the explanation. The first harmony of 400, as has been already remarked, probably represents the rulers; the second and oblong harmony of 7600, the people.
And here we take leave of the difficulty. The discovery of the riddle would be useless, and would throw no light on ancient mathematics. The point of interest is that Plato should have used such a symbol, and that so much of the Pythagorean spirit should have prevailed in him. His general meaning is that divine creation is perfect, and is represented or presided over by a perfect or cyclical number; human generation is imperfect, and represented or presided over by an imperfect number or series of numbers. The number 5040, which is the number of the citizens in the Laws, is expressly based by him on utilitarian grounds, namely, the convenience of the number for division; it is also made up of the first seven digits multiplied by one another. The contrast of the perfect and imperfect number may have been easily suggested by the corrections of the cycle, which were made first by Meton and secondly by Callippus; (the latter is said to have been a pupil of Plato). Of the degree of importance or of exactness to be attributed to the problem, the number of the tyrant in Book IX (729 = 365 x 2), and the slight correction of the error in the number 5040/12 (Laws), may furnish a criterion. There is nothing surprising in the circumstance that those who were seeking for order in nature and had found order in number, should have imagined one to give law to the other. Plato believes in a power of number far beyond what he could see realized in the world around him, and he knows the great influence which ‘the little matter of 1, 2, 3’ exercises upon education. He may even be thought to have a prophetic anticipation of the discoveries of Quetelet and others, that numbers depend upon numbers; e.g.—in population, the numbers of births and the respective numbers of children born of either sex, on the respective ages of parents, i.e. on other numbers.
