Justice hardly comes into the scheme; it is rather a virtue of the State than of the individual, and it has been thought by some that the book devoted to it in the "Ethics" has been misplaced. Justice is of two kinds, distributive and corrective. Its fundamental idea {320} is the assignment of advantages and disadvantages according to merit. Distributive justice assigns honours and rewards according to the worth of the individuals involved. Corrective justice has to do with punishment. If a man improperly obtains an advantage, things must be equalized by the imposition on him of a corresponding disadvantage. Justice, however, is a general principle, and no general principle is equal to the complexity of life. Special cases cannot be foreseen, The necessary adjustment of human relations arising from this cause is equity. Aristotle is a pronounced supporter of the freedom of the will. He censures Socrates because the latter's theory of virtue practically amounts to a denial of freedom. According to Socrates, whoever thinks right must necessarily do right. But this is equivalent to denying a man's power to choose evil. And if he cannot choose evil, he cannot choose good. For the right-thinking man does not do right voluntarily, but necessarily. Aristotle believed, on the contrary, that man has the choice of good and evil. The doctrine of Socrates makes all actions involuntary. But in Aristotle's opinion only actions performed under forcible compulsion are involuntary. Aristotle did not, however, consider the special difficulties in the theory of free will which in modern times have made it one of the most thorny of all philosophical problems. Hence his treatment of the subject is not of great value to us. _(b) The State_. Politics is not a separate subject from Ethics. It is merely another division of the same subject. And {321} this, not merely because politics is the ethics of the State as against the individual, but because the morality of the individual really finds its end in the State, and is impossible without it. Aristotle agrees with Plato that the object of the State is the virtue and happiness of the citizens, which are impossible except in the State. For man is a political animal by nature, as is proved by his possession of speech, which would be useless to any save a social being. And the phrase "by nature" means the same here as elsewhere in Aristotle. It means that the State is the end of the individual, and that activity in the State is part of man's essential function. The State, in fact, is the form, the individual, the matter. The State provides both an education in virtue and the necessary opportunities for its exercise. Without it man would not be man at all. He would be a savage animal.
