360. I must explain how love catches fire and breaks out into zeal when it is attacked, as fire does into flame. Love dwells in a person's will; but it is not in the will, but in the intellect, that it catches fire. For in the will it resembles fire, but in the intellect flame. Love in the will cannot know anything about itself, because there it has no feeling for itself, nor does it act there of itself. This happens in the intellect and its thought-processes. When therefore love is attacked, it rouses itself in the intellect, which it does through various forms of reasoning. These reasonings are like pieces of wood which catch fire and so blaze. So they are like so much tinder or so much combustible material; these produce that spiritual flame, which is very varied.
