Note A — Chapter I

The wide uses of the English word love add to the difficulty. I shall take the liberty of limiting the term here to imaginative passion, to being in love, excluding all other ways of loving. It follows that love—like its shadow, jealousy—will often be merely an ingredient in an actual state of feeling; friendship and confidence, with satisfaction at being liked in return, will often be mingled with it. We shall have to separate physiologically things which in consciousness exist undivided, since a philosophic description is bound to be analytic and cannot render everything at once. Where a poet might conceive a new composite, making it live, a moralist must dissect the experience and rest in its eternal elements.
