Any institution becomes a community - whether it's a high school or a boarding school or a publishing company or a small town where everybody knows certain things about people. ↗
Wherever the citizen becomes indifferent to his fellows, so will the husband be to his wife, and the father of a family toward the members of his household. ↗
The instruction we find in books is like fire. We fetch it from our neighbours, kindle it at home, communicate it to others, and it becomes the property of all. ↗
