Rambam - The purpose of Man

(3) Hear now what I have to say after having given the above explanation. The ancient and the modern philosophers have shown that man can acquire four kinds of perfection. The first kind, the lowest, in the acquisition of which people spend their days, is perfection as regards property; the possession of money, garments, furniture, servants, land, and the like; the possession of the title of a great king belongs to this class. There is no close connexion between this possession and its possessor; it is a perfectly imaginary relation when on account of the great advantage a person derives from these possessions, he says, This is my house, this is my servant, this is my money, and these are my hosts and armies. For when he examines himself he will find that all these things are external, and their qualities are entirely independent of the possessor. When, therefore, that relation ceases, he that has been a great king may one morning find that there is no difference between him and the lowest person, and yet no change has taken place in the things which were ascribed to him. The philosophers have shown that he whose sole aim in all his exertions and endeavours is the possession of this kind of perfection, only seeks perfectly imaginary and transient things; and even if these remain his property all his lifetime, they do not give him any perfection.

(4) The second kind is more closely related to man's body than the first. It includes the perfection of the shape, constitution, and form of mans body; the utmost evenness of temperaments, and the proper order and strength of his limbs. This kind of perfection must likewise be excluded from forming our chief aim; because it is a perfection of the body, and man does not possess it as man, but as a living being: he has this property besides in common with the lowest animal; and even if a person possesses the greatest possible strength, he could not be as strong as a mule, much less can he be as strong as a lion or an elephant; he, therefore, can at the utmost have strength that might enable him to carry a heavy burden, or break a thick substance, or do similar things, in which there is no great profit for the body. The soul derives no profit whatever from this kind of perfection.

(5) The third kind of perfection is more closely connected with man himself than the second perfection. It includes moral perfection, the highest degree of excellency in man's character. Most of the precepts aim at producing this perfection; but even this kind is only a preparation for another perfection, and is not sought for its own sake. For all moral principles concern the relation of man to his neighbour; the perfection of man's moral principles is, as it were, given to man for the benefit of mankind. Imagine a person being alone, and having no connexion whatever with any other person, all his good moral principles are at rest, they are not required, and give man no perfection whatever. These principles are only necessary and useful when man comes in contact with others.

(6) The fourth kind of perfection is the true perfection of man: the possession of the highest, intellectual faculties; the possession of such notions which lead to true metaphysical opinions as regards God. With this perfection man has obtained his final object; it gives him true human perfection; it remains to him alone; it gives him immortality, and on its account he is called man. Examine the first three kinds of perfection, you will find that, if you possess them, they are not your property, but the property of others; according to the ordinary view, however, they belong to you and to others. But the last kind of perfection is exclusively yours; no one else owns any part of it, "They shall be only thine own, and not strangers' with thee" (Prov. 5:17). Your aim must therefore be to attain this [fourth] perfection that is exclusively yours, and you ought not to continue to work and weary yourself for that which belongs to others, whilst neglecting your soul till it has lost entirely its original purity through the dominion of the bodily powers over it. The same idea is expressed in the beginning of those poems, which allegorically represent the state of our soul. "My mother's children were angry with me; they made me the keeper of the vineyards; but mine own vineyard have I not kept" (Song 1:6). Also the following passage refers to the same subject, "Lest thou give thine honour unto others, and thy years unto the cruel" (Prov. 5:9).

(7) The prophets have likewise explained unto us these things, and have expressed the same opinion on them as the philosophers. They say distinctly that perfection in property, in health, or in character, is not a perfection worthy to be sought as a cause of pride and glory for us: that the knowledge of God, i.e., true wisdom, is the only perfection which we should seek, and in which we should glorify ourselves. Jeremiah, referring to these four kinds of perfection, says: "Thus saith the Lord, Let not the wise man glory in his wisdom, neither let the mighty man glory in his might, let not the rich man glory in his riches; but let him that glorieth glory in this, that he understandeth and knoweth me" (Jer. 9:22, 23). See how the prophet arranged them according to their estimation in the eyes of the multitude. The rich man occupies the first rank; next is the mighty man; and then the wise man; that is, the man of good moral principles: for in the eyes of the multitude, who are addressed in these words, he is likewise a great man. This is the reason why the three classes are enumerated in this order.
