766. Is social life founded in nature?

"Certainly; God has made man for living in society. It is not without a purpose that God has given to man the faculty of speech and the other faculties necessary to the life of relation."

767. Is absolute isolation contrary to the law of nature?

"Yes, since man instinctively seeks society, and since all men are intended to help forward the work of progress by aiding one another."

768. Does man, in seeking society, only yield to a personal feeling, or is there, in this feeling, a wider providential end?

"Man must progress; he cannot do so alone, because, as he does not possess all faculties, he needs the contact of other men. In isolation he becomes brutified and etiolated."

No man possesses the complete range of faculties. Through social union men complete one another, and thus mutually secure their well-being and progress. It is because they need each other's help that they have been formed for living in society, and not in isolation.
