Ordinarily, however, and for the time being, it may be possible to practically obliterate a passion. “All love may be expelled by love, as poisons are by other poisons,” says Dryden. And if the allopathic remedies described in the preceding paragraphs should fail to effect a cure, the lover may find the homœopathic principle of _similia similibus_ more successful. Heine, in his posthumous Memoirs, thus refers to this principle of curing like with like:— “In love, as in the Roman Catholic religion, there is a provisional purgatory in which mortals are allowed to get used gradually to being roasted before they get into the real eternal hell.... In all honesty, what a terrible thing is love for a woman. Inoculation is herein of no use.... Very wise and experienced physicians counsel a change of locality in the opinion that removal from the presence of the enchantress will also break the charm. Perhaps the homœopathic principle, by which woman cures us of woman, is the best of all.... It was ordained that I should be visited more severely than other mortals by this malady, the heart-pox.... The most effective antidote to women are women; true, this implies an attempt to expel Satan with Beelzebub; and in such a case the medicine is often more noxious still than the malady. But it is at any rate a change, and in a disconsolate love-affair a change of the inamorata is unquestionably the best policy.” PROGNOSIS OR CHANCES OF RECOVERY After carefully following all the foregoing rules regarding absence, travel, employment, dwelling on the miseries of marriage, the weaknesses of women in general and one woman in particular, the disappointed lover may boldly return and face her again. The chances are ten to one he will find himself—more in love than ever! Women are magicians. No wonder they were burned as witches in the Middle Ages. NATIONALITY AND LOVE Romantic love—commonly considered immutable—not only displays countless individual variations in regard to duration and degrees of intensity, but has a sort of “local colour” in each country; or, to keep up our old metaphor, a varying clangtint, depending on the greater or less prominence of certain “overtones.” To describe all these varieties of Love would require a separate volume. And since all the most interesting forms of the romantic passion are to be met with in France, Italy, Spain, Germany, England, and America, it will suffice to briefly characterise Love in those countries. FRENCH LOVE As literary luck would have it, the subject of French Love follows naturally upon the subject of the last chapter, the _Remedia Amoris_.
