Selection from Arcana Coelestia ~ Emanuel Swedenborg
It is a common saying that everyone is neighbor to himself, that is, that one should take care of himself first of all. The doctrine of charity teaches how the case herein is —Everyone is neighbor to himself, not in the first, but in the last place. In a prior place are others who are in good; in a still prior place is a society of many; in a place still prior is our country; in a place still prior is the church; in a place still prior is the Lord's kingdom; and above all men and all things is the Lord.
The saying that everyone is neighbor to himself, and that he must take care of himself first of all, is to be understood in this way —
Everyone must make provision for himself so as to have the necessities of life, as food, clothing, a place to dwell in, and other things which are necessarily required in the civil life where he is; and this not only for himself, but also for his family; and not only for the present time, but also for the future. Unless each person procures for himself the necessities of life, he cannot be in a state to exercise charity toward the neighbor, for he is in need of all things.
The end in view declares in what way each person must be neighbor to himself, and must first of all take care of himself. If the end is that he may become richer than others merely for the sake of riches, pleasure, eminence, and the like, the end is evil; and therefore he who from such an end believes he is neighbor to himself, injures himself to eternity. But if the end is that he may acquire wealth for the sake of the necessities of life, for himself and for his family, so as to be in a state to do what is good according to the commandments of the doctrine of charity, he takes care of himself for eternity. The end itself makes the man, for the end is his love, because everyone has as the end that which he loves.
How the case herein is can be further seen from this similar example —
Everyone ought to take care of his body in respect to its food and clothing. This must come first, but to the end that there may be a sound mind in a sound body. And everyone ought to take care of his mind in respect to its food, namely, in respect to such things as belong to intelligence and wisdom, to the end that his mind may thus be in a state to serve the Lord; he who does this, takes good care of himself for eternity. But he who takes care of his body merely for the sake of the body, and does not think of soundness of mind, and who does not take care of his mind in respect to such things as are of intelligence and wisdom, but in respect to such things as are contrary thereto, takes bad care of himself for eternity. From all this it is evident in what way everyone ought to be neighbor to himself, namely, not in the first place but in the last; for the end must not be for himself, but for others; and where the end is, there is the first.
Moreover, the case herein is like that of a man who is building a house. He must first lay the foundation; but the foundation must be for the house, and the house for a place to dwell in. And so everyone must first take care of himself, yet not for himself, but in order that he may be in a state to be of service to the neighbor, thus to his country, to the church, and above all to the Lord. He who believes that he is neighbor to himself in the first place, is like one who regards the foundation as the end, and not the house and dwelling in it; when yet the dwelling is the very first and last end, and the house together with its foundation is only a means to the end.
As is the case with possessions, so also is it with honors in the world; everyone is at liberty to provide himself with these also, yet not for the sake of himself, but for the sake of the neighbor; he who provides them for the sake of himself, provides ill for himself; but he who provides them for the sake of the neighbor, provides well for himself.
For he who turns his ends to himself turns himself toward hell; but he who turns his ends from himself to the neighbor, turns himself toward heaven.
