Man is called by nature to live in society; for he needs many things which are necessary to his life, and which by himself he cannot procure for himself. Whence it follows that man naturally becomes part of a group, to procure him the means of living well.He needs this assistance for two reasons.First, in order that he may obtain the elementary necessities of life; this he does in the domestic circle of which he is a part. Every man receives from his parents life and nourishment and education; and the reciprocal aid of the family members facilitates the mutual provision of the necessities of life. But there is a second reason why the individual is helped by the group of which he is a part, and in which alone he finds his adequate well-being. And this is, that he may not only live, but live the good life---which is enabled by the opportunities of social intercourse. Thus civil society aids the individual in obtaining the material necessities, by uniting in the same city a great number of crafts, which could not be so united in the same family. And civil society also assists him in the moral life. From the text, we can learn that civil society assits man in the ______ and _____ life.
