Love in itself is not to love self, but to love others and to be conjoined with them by love. An essential of love also is to be loved by others, for thus is conjunction effected. The essence of all love consists in conjunction, it is indeed its life which is called enjoyment, delight, sweetness, blessedness, happiness and felicity. Love consists in this that its own is another's; and to feel another's joy as joy in oneself, this is to love. But to feel one's joy in another and not the other's joy in oneself, this is not to love, for the latter is loving one's self, the former loving the neighbour. The two kinds of love are diametrically opposed to one another. Either kind of love does indeed conjoin; and it does not appear that to love oneself, that is, to love oneself in another, disjoins. But yet it does disjoin to such a degree that, so far as anyone has loved another in this manner, so far he afterwards hates him. For such a conjunction is by itself successively dissolved, and then, in like measure, the love becomes hatred.
