But in the rest of the article St. Thomas goes farther still. Not merely does he hold the moral proposition that private property is lawful, but he adds to it the social proposition that private property is necessary. "It is even necessary," says he, "for human life, and that for three reasons. Firstly, because everyone is more solicitous about procuring what belongs to himself alone than that which is common to all or many, since each shunning labour leaves to another what is the common burden of all, as happens with a multitude of servants. Secondly, because human affairs are conducted in a more orderly fashion if each has his own duty of procuring a certain thing, while there would be confusion if each should procure things haphazard. Thirdly, because in this way the peace of men is better preserved, for each is content with his own. Whence we see that strife more frequently arises among those who hold a thing in common and individually. The other office which is man's concerning exterior things, is the use of them; and with regard to this a man ought not to hold exterior things as his own, but as common to all, that he may portion them out to others readily in time of need." (The translation is taken from _New Things and Old_, by H. C. O'Neill, 1909, London, pp. 253-4.) The wording and argument of this will bear, and is well worth, careful analysis. For St. Thomas was a man, as Huxley witnesses, of unique intellectual power, and, moreover, his theories on private property were immediately accepted by all the schoolmen. Each succeeding writer did little else than make more clear and defined the outlines of the reasoning here elaborated. We shall, therefore, make no further apology for an attempt to set out the lines of thought sketched by Aquinas.
