The Stranger begins the enquiry by making a division of the arts and sciences into theoretical and practical--the one kind concerned with knowledge exclusively, and the other with action; arithmetic and the mathematical sciences are examples of the former, and carpentering and handicraft arts of the latter (compare Philebus). Under which of the two shall we place the Statesman? Or rather, shall we not first ask, whether the king, statesman, master, householder, practise one art or many? As the adviser of a physician may be said to have medical science and to be a physician, so the adviser of a king has royal science and is a king. And the master of a large household may be compared to the ruler of a small state. Hence we conclude that the science of the king, statesman, and householder is one and the same. And this science is akin to knowledge rather than to action. For a king rules with his mind, and not with his hands. But theoretical science may be a science either of judging, like arithmetic, or of ruling and superintending, like that of the architect or master-builder. And the science of the king is of the latter nature; but the power which he exercises is underived and uncontrolled,--a characteristic which distinguishes him from heralds, prophets, and other inferior officers. He is the wholesale dealer in command, and the herald, or other officer, retails his commands to others. Again, a ruler is concerned with the production of some object, and objects may be divided into living and lifeless, and rulers into the rulers of living and lifeless objects. And the king is not like the master-builder, concerned with lifeless matter, but has the task of managing living animals. And the tending of living animals may be either a tending of individuals, or a managing of herds. And the Statesman is not a groom, but a herdsman, and his art may be called either the art of managing a herd, or the art of collective management:--Which do you prefer? 'No matter.' Very good, Socrates, and if you are not too particular about words you will be all the richer some day in true wisdom. But how would you subdivide the herdsman's art? 'I should say, that there is one management of men, and another of beasts.' Very good, but you are in too great a hurry to get to man. All divisions which are rightly made should cut through the middle; if you attend to this rule, you will be more likely to arrive at classes. 'I do not understand the nature of my mistake.' Your division was like a division of the human race into Hellenes and Barbarians, or into Lydians or Phrygians and all other nations, instead of into male and female; or like a division of number into ten thousand and all other numbers, instead of into odd and even. And I should like you to observe further, that though I maintain a class to be a part, there is no similar necessity for a part to be a class. But to return to your division, you spoke of men and other animals as
