"Rien n'est beau que le vrai; le vrai seul est aimable."—BOIL.
Experience, although not that of everyday, verifies that that which as a rule begins only as a strong and yet controllable inclination, may develop, under certain conditions, into a passion, the ardour of which surpasses that of every other. It will ignore all considerations, overcome all kinds of obstacles with incredible strength and persistence. A man, in order to have his love gratified, will unhesitatingly risk his life; in fact, if his love is absolutely rejected, he will sacrifice his life into the bargain. The Werthers and Jacopo Ortis do not only exist in romances; Europe produces every year at least half-a-dozen like them: sed ignotis perierunt mortibus illi: for their sufferings are chronicled by the writer of official registers or by the reporters of newspapers. Indeed, readers of the police news in English and French newspapers will confirm what I have said.
Love drives a still greater number of people into the lunatic asylum. There is a case of some sort every year of two lovers committing suicide together because material circumstances happen to be unfavourable to their union. By the way, I cannot understand how it is that such people, who are confident of each other's love, and expect to find their greatest happiness in the enjoyment of it, do not avoid taking extreme steps, and prefer suffering every discomfort to sacrificing with their lives a happiness which is greater than any other they can conceive. As far as lesser phases and passages of love are concerned, all of us have them daily before our eyes, and, if we are not old, the most of us in our hearts.
After what has been brought to mind, one cannot doubt either the reality or importance of love. Instead, therefore, of wondering why a philosopher for once in a way writes on this subject, which has been constantly the theme of poets, rather should one be surprised that love, which always plays such an important rôle in a man's life, has scarcely ever been considered at all by philosophers, and that it still stands as material for them to make use of.
Plato has devoted himself more than any one else to the subject of love, especially in the Symposium and the Phaedrus; what he has said about it, however, comes within the sphere of myth, fable, and raillery, and only applies for the most part to the love of a Greek youth. The little that Rousseau says in his Discours sur l'inégalité is neither true nor satisfactory. Kant's disquisition on love in the third part of his treatise, Ueber das Gefühl des Schönen und Erhabenen, is very superficial; it shows that he has not thoroughly gone into the subject, and therefore it is somewhat untrue. Finally, Platner's treatment of it in his Anthropology will be found by every one to be insipid and shallow.
To amuse the reader, on the other hand, Spinoza's definition deserves to be quoted because of its exuberant naïveté: Amor est titillatio, concomitante idea causae externae (Eth. iv., prop. 44). It is not my intention to be either influenced or to contradict what has been written by my predecessors; the subject has forced itself upon me objectively, and has of itself become inseparable from my consideration of the world. Moreover, I shall expect least approval from those people who are for the moment enchained by this passion, and in consequence try to express their exuberant feelings in the most sublime and ethereal images. My view will seem to them too physical, too material, however metaphysical, nay, transcendent it is fundamentally.
First of all let them take into consideration that the creature whom they are idealising to-day in madrigals and sonnets would have been ignored almost entirely by them if she had been born eighteen years previously.
Every kind of love, however ethereal it may seem to be, springs entirely from the instinct of sex; indeed, it is absolutely this instinct, only in a more definite, specialised, and perhaps, strictly speaking, more individualised form. If, bearing this in mind, one considers the important rôle which love plays in all its phases and degrees, not only in dramas and novels, but also in the real world, where next to one's love of life it shows itself as the strongest and most active of all motives; if one considers that it constantly occupies half the capacities and thoughts of the younger part of humanity, and is the final goal of almost every human effort; that it influences adversely the most important affairs; that it hourly disturbs the most earnest occupations; that it sometimes deranges even the greatest intellects for a time; that it is not afraid of interrupting the transactions of statesmen or the investigations of men of learning; that it knows how to leave its love-letters and locks of hair in ministerial portfolios and philosophical manuscripts; that it knows equally well how to plan the most complicated and wicked affairs, to dissolve the most important relations, to break the strongest ties; that life, health, riches, rank, and happiness are sometimes sacrificed for its sake; that it makes the otherwise honest, perfidious, and a man who has been hitherto faithful a betrayer, and, altogether, appears as a hostile demon whose object is to overthrow, confuse, and upset everything it comes across: if all this is taken into consideration one will have reason to ask—"Why is there all this noise? Why all this crowding, blustering, anguish, and want? Why should such a trifle play so important a part and create disturbance and confusion in the well-regulated life of mankind?" But to the earnest investigator the spirit of truth gradually unfolds the answer: it is not a trifle one is dealing with; the importance of love is absolutely in keeping with the seriousness and zeal with which it is prosecuted. The ultimate aim of all love-affairs, whether they be of a tragic or comic nature, is really more important than all other aims in human life, and therefore is perfectly deserving of that profound seriousness with which it is pursued.
As a matter of fact, love determines nothing less than the establishment of the next generation. The existence and nature of the dramatis personae who come on to the scene when we have made our exit have been determined by some frivolous love-affair. As the being, the existentia of these future people is conditioned by our instinct of sex in general, so is the nature, the essentia, of these same people conditioned by the selection that the individual makes for his satisfaction, that is to say, by love, and is thereby in every respect irrevocably established. This is the key of the problem. In applying it, we shall understand it more fully if we analyse the various degrees of love, from the most fleeting sensation to the most ardent passion; we shall then see that the difference arises from the degree of individualisation of the choice. All the love-affairs of the present generation taken altogether are accordingly the meditatio compositionis generationis futurae, e qua iterum pendent innumerae generationes of mankind. Love is of such high import, because it has nothing to do with the weal or woe of the present individual, as every other matter has; it has to secure the existence and special nature of the human race in future times; hence the will of the individual appears in a higher aspect as the will of the species; and this it is that gives a pathetic and sublime import to love-affairs, and makes their raptures and troubles transcendent, emotions which poets for centuries have not tired of depicting in a variety of ways. There is no subject that can rouse the same interest as love, since it concerns both the weal and woe of the species, and is related to every other which only concerns the welfare of the individual as body to surface.
This is why it is so difficult to make a drama interesting if it possesses no love motive; on the other hand, the subject is never exhausted, although it is constantly being utilised.
