766- Is societal life natural?
“Certainly. God has made humans for living in society; otherwise, it would have been needless for God to have endowed them with speech and all the other faculties necessary for a life of relationships.”
767- Is absolute isolation contrary to the law of nature?
“Yes, because people instinctively seek societal living and because all of them must cooperate in humankind’s progress by mutually helping one another.”
768- In seeking societal living, do people only obey a personal sentiment, or is there a wider, providential purpose involved?
“Humans must progress; they cannot do so alone, however, since they do not all possess every faculty – they need contact with others. In isolation, they become brutish and withered.”
No single individual possesses the complete range of faculties. It is through societal union that individuals complete one another in order to ensure their own welfare and progress. It is because they need one another that they have been created to live in society and not in isolation.
