Good is the neighbor, because good belongs to the will, and the will is the being [esse] of man's life. The truth of the understanding is also the neighbor, but only so far as it proceeds from the good
of the will; for the good of the will take form in the understanding, and makes itself visible there is the light of reason. That good is the neighbor is evident from all experience. Who loves a person
except from the quality of his will and understanding, that is, from what is good and just in him? For example, who loves a king, a prince, a general, a governor, a consul, any magistrate or judge,
except for the judgment from which they act and speak? Who loves a primate, a minister of the church, or a canon, except for his learning, his integrity of life, and his zeal for the salvation of souls?
Who loves the general of an army or any officer over him, except for bravery combined with prudence? Who loves a merchant except for his honesty? Who loves a workman or a servant, except for his
fidelity? Nay, who loves a tree except for its fruit, the soil except for its fertility, a precious stone except for its value? and so on. And what is remarkable, it is not only the upright man who loves
what is good and just in another, the man who is not upright does so also, because with him he is in no fear of losing reputation, honor, or wealth. But the love of good in one who is not upright,
is not love of the neighbor; for he loves another interiorly only so far as he is of service to him. But loving what is good in another from the good in oneself is genuine love to the neighbor; for
the goods then kiss and mutually unite with each other.
