(3) This also is evident, that [human] life becomes different from disposition and action. But it is necessary that the disposition should be either worthy or depraved; and that action should be attended either with felicity or misery. And a worthy disposition, indeed, participates of virtue; but a bad one of vice. With respect to actions, also, those that are prosperous are attended with felicity; (for they derive their completion through looking to reason) but those that are unfortunate, are attended with misery; for they are frustrated of the end. Hence, it is not only necessary to learn virtue, but also to possess and use it, either for security, or increase, [of property when it is too little] or, which is the greatest thing of all, for the emendation of families and cities.

For it is not only necessary to have the possession of things beautiful, but also the use of them. All these things, however, will take place, when a man lives in a city that uses equitable laws. And these, indeed, I say, are what is called the horn of Amalthea. For all things are contained in equitable legislation. And without this, the greatest good of human nature can neither be effected, nor, when effected, be increased and become permanent. For this comprehends in itself virtue, and the tendency to virtue; because excellent natures are generated according to it. Manners, likewise, studies, and laws, subsist through this in the most excellent condition; and besides these, rightly-deciding reason, and piety and sanctity towards the most honorable natures.

So that it is necessary that he who is to be happy, and whose life is to be prosperous, should live and die in a country governed by equitable laws, relinquishing all illegality. At the same time what has been said is attended with necessity. For man is a part of society, and hence from the same reasoning, will become entire and perfect, if he not only associates with others, but associates in a becoming manner. For some things are naturally adapted to subsist in many things, and not in one thing; others in one thing, and not in many; but others both in many, and in one thing, and on this account in one thing, because in many. For harmony, indeed, and symphony and number, are naturally adapted to be ingenerated in many things.

For nothing which makes a whole from these parts, is sufficient to itself. But acuteness of seeing and hearing, and swiftness of feet, subsist in one thing alone. Felicity, however, and the virtue of soul, subsist both in one thing and in many, in a whole, and in the universe. And on this account they subsist in one thing, because they also subsist in many: and they subsist in many, because they are inherent in a whole and in the universe. For the orderly distribution of the whole nature of things methodically arranges each particular. And the orderly distribution of particulars gives completion to the whole of things and to the universe. But this follows from the whole being naturally prior to the part, and not the part to the whole . For if the world was not, neither the sun nor the moon would exist, nor the planets, nor the fixed stars. But the world existing, each of these also exists.

(3) Now if we draw no distinction as to kinds of life, everything that lives will be capable of happiness, and those will be effectively happy who possess that one common gift of which every living thing is by nature receptive. We could not deny it to the irrational whilst allowing it to the rational. If happiness were inherent in the bare being-alive, the common ground in which the cause of happiness could always take root would be simply life.

Those, then, that set happiness not in the mere living but in the reasoning life seem to overlook the fact that they are not really making it depend upon life at all: they admit that this reasoning faculty, round which they centre happiness, is a property : the subject, to them, must be the Reasoning-Life since it is in this double term that they find the basis of the happiness: so that they are making it consist not in life but in a particular kind of life- not, of course, a species formally opposite but, in terminology, standing as an "earlier" to a "later" in the one Kind.

Now in common use this word "Life" embraces many forms which shade down from primal to secondary and so on, all massed under the common term- life of plant and life of animal- each phase brighter or dimmer than its next: and so it evidently must be with the Good-of-Life. And if thing is ever the image of thing, so every Good must always be the image of a higher Good.

If mere Being is insufficient, if happiness demands fulness of life, and exists, therefore, where nothing is lacking of all that belongs to the idea of life, then happiness can exist only in a being that lives fully.

And such a one will possess not merely the good, but the Supreme Good if, that is to say, in the realm of existents the Supreme Good can be no other than the authentically living, no other than Life in its greatest plenitude, life in which the good is present as something essential not as something brought from without, a life needing no foreign substance called in from a foreign realm, to establish it in good.

For what could be added to the fullest life to make it the best life? If anyone should answer, "The nature of Good" , the reply would certainly be near our thought, but we are not seeking the Cause but the main constituent.

It has been said more than once that the perfect life and the true life, the essential life, is in the Intellectual Nature beyond this sphere, and that all other forms of life are incomplete, are phantoms of life, imperfect, not pure, not more truly life than they are its contrary: here let it be said succinctly that since all living things proceed from the one principle but possess life in different degrees, this principle must be the first life and the most complete.

(4) There are likewise three definite times of human life; one of prosperity; another of adversity; and a third subsisting between these. Since therefore, he is a good man who possesses and uses virtue; but he uses it according to three seasons; for he uses it either in adversity, or in prosperity, or in the time between these; and in adversity indeed he is unhappy, but in prosperity happy, and in the middle condition, he is not happy [though he is not miserable];—this being the case, it is evident that felicity is nothing else than the use of virtue in prosperity. We now speak, however, of the felicity of man. But man is not soul alone, but is likewise body. For the animal which consists of both, and that which is constituted from things of this kind is man.

For though the body is naturally adapted to be the instrument of the soul, yet this as well as the soul is a part of man [so far as he is an animal. ] Hence of goods also, some are the goods of man, but others, of the parts of man. And the good of man, indeed, is felicity. But of the parts of man, the good of the soul is prudence, fortitude, justice, and temperance. And the good of the body is beauty, health, a good corporeal habit, and excellence of sensation. With respect to externals however, wealth, glory, honor, and nobility, are naturally adapted to be attendant on man, and to follow precedaneous goods. The less, also, are ministrant to the greater goods.

Thus friendship, glory, and wealth, are ministrant both to the body and the soul; but health, strength, and excellence of sensation, are subservient to the soul; and prudence [i. e. wisdom] and justice are ministrant to the intellect of the soul. Intellect, however, is the satellite of Deity. For God is the most excellent, and the leader and ruler of all things. And for the sake of these, it is necessary that other goods should be present. For the general, indeed, is the leader of the army; the pilot, of the ship; God, of the world; and intellect, of soul. But prudence is the leader of the felicity pertaining to life. For prudence is nothing else than the science of the felicity which respects human life, or the science of the goods which naturally pertain to man.

(1) The perfect life of man falls short indeed of the life of God, because it is not self-perfect, but surpasses that of irrational animals, because it participates of virtue and felicity. For neither is God in want of external causes; since being naturally good and happy, he is perfect from himself; nor any irrational animal. For brutes being destitute of reason, they are also destitute of the sciences pertaining to actions. But the nature of man partly consists of his own proper deliberate choice, and partly is in want of the assistance derived from divinity. For that which is capable of being fashioned by reason, which has an intellectual perception of things beautiful and base, can erectly extend itself from earth, and look to heaven, and can perceive with the eye of intellect the highest Gods,—that which is capable of all this, participates likewise of assistance from the Gods.

But in consequence of possessing will, deliberate choice, and a principle of such a kind in itself as enables it to study virtue, and to be agitated by the storms of vice, to follow, and also to apostatize from the Gods,—it is likewise able to be moved by itself. Hence it is a partaker of praise and blame, honor and ignominy, partly from the Gods and partly from men, according as it zealously applies itself either to virtue or vice. For the whole reason of the thing is as follows: Divinity introduced man into the world as a most exquisite animal, to be reciprocally honored with himself, and as the eye of the orderly distribution of things . Hence also man gave names to things, becoming himself the character of them.

He likewise invented letters, procuring through these a treasury of memory. And he imitated the established order of the universe, co-harmonizing by judicial proceedings and laws the communion of cities. For no work is performed by men more decorous to the world, or more worthy of the notice of the Gods, than the apt constitution of a city governed by good laws, and an orderly distribution of laws and a polity. For though each man himself by himself is nothing, and is not himself by himself sufficient to lead a life conformable to the common concord, and apt composition of a polity, yet he is well adapted to the whole and to the perfect system of society. For the life of man is the image of a lyre accurately [harmonized,] and in every respect perfect.

For every lyre requires these three things, apparatus, apt composition, and a certain musical contrectation. And apparatus indeed, is a preparation of all the appropriate parts; viz. of the chords, and of the instruments which co-operate with the well-sounding and striking of the lyre. But the apt composition is the commixture of the sounds with each other. And the musical contrectation is the motion of these conformably to the apt composition. Thus also human life requires these same three things. Apparatus, indeed, which is the completion of the parts of life. But the parts of life are the goods of the body, of riches, renown, and friends. The apt composition is the co-arrangement of these according to virtue and the laws.

And the musical contrectation is the commixture of these conformably to virtue and the laws; virtue sailing with a prosperous wind, and having nothing externally resisting it. For felicity does not consist in being driven from the purpose of voluntary intentions, but in obtaining them; nor in virtue being without attendants and ministrant aids; but in completely possessing its own proper powers which are adapted to actions. For man is not self-perfect, but imperfect. And he becomes perfect, partly from himself, and partly from an external cause. He is likewise perfect, either according to nature, or according to life. And he is perfect indeed according to nature, if he becomes a good man. For the virtue of each thing is the summit and perfection of the nature of that thing.

Thus the virtue of the eyes is the summit and perfection of the nature of the eyes; and this is also true of the virtue of the ears. Thus too, the virtue of man is the summit and perfection of the nature of man. But man is perfect according to life, when he becomes happy. For felicity is the perfection and completion of human goods. Hence, again, virtue and prosperity become the parts of the life of man. And virtue, indeed, is a part of him so far as he is soul, but prosperity so far as he is connected with body. But both are parts of him so far as he is an animal. For it is the province of virtue to use in a becoming manner the goods which are conformable to nature; but of prosperity to impart the use of them.

And the former, indeed, imparts deliberate choice and right reason; but the latter, energies and actions. For to wish what is beautiful in conduct and to endure things of a dreadful nature, is the proper business of virtue. But it is the work of prosperity to render deliberate choice successful, and to cause actions to arrive at the [desired] end. For the general conquers in conjunction with virtue and good fortune. The pilot sails well in conjunction with art and prosperous winds. The eye sees well in conjunction with acuteness of vision and light. And the life of man becomes most excellent through virtue itself, and prosperity.
