87. 4. The human race is the neighbour in the widest sense; but, because it is distinguished into empires, kingdoms, and republics, any one of these is a neighbour according to the good of its religion and of its moral qualities, and according to the good which it performs to one's country, and which makes one with its own good. These subjects are too extensive to be separately elucidated. It is enough that, if some man or other, from some kingdom or other, is at my house, and I am staying in the same house as he is, or I in the same city, to me he is then the neighbour according to his good. It is the same with all in that kingdom whom that particular man resembles. Supposing he is an ambassador of that kingdom, representing his king and therefore the kingdom; it cannot then be denied that to me he is the neighbour according to the good of his religion and of his moral qualities, and according as he wishes good to my country and his own; especially in so far as this makes one with his own good.
