As for Dante, he fully realised the “sweet pain” of Love, as he called it. As far back as Plato’s Timæus we find that love, as then understood, was regarded as “a mixture of pleasure and pain.”
“’Tis the pest of love,” sings Keats, “that fairest joys bring most unrest.” Thackeray speaks of “the delights and tortures, the jealousy and wakefulness, the longing and raptures, the frantic despair and elation, attendant upon the passion of love.” But it is superfluous to cite modern authors, for volumes might be filled with quotations attesting that Love is neither a simple “lætitia,” as Spinoza defined it, nor “a species of melancholy,” but a mixture of joy and sadness, of rapture and woe.
Shakspere’s “violent sorrow seems a modern ecstasy” might be adopted as a general motto for a book on the psychology and history of Love.
Love, it is true, is not the only passion characterised by such a paradoxical mixture of moods. Thus in Macbeth the sentence, “on the torture of the mind to lie in restless ecstasy,” does not refer to Love; and John Fletcher, too, sings in a general way—
“There’s naught in this life sweet
If man were wise to see’t,
But only melancholy,
O sweetest Melancholy!”
A German author, Oswald Zimmermann, has even written a volume of almost two hundred pages, wherein he endeavours to analyse various emotions and historic phenomena, in which pleasure and pain are intimately associated. He has chapters on the Beautiful in Art and in Nature, on Death, on Mysticism, on the ancient festivals of Dionysus and Aphrodite, on the mediæval flagellants, on lust and cruelty, on various epochs of modern literature, etc. His book bears the curious title Die Wonne des Leids, because he holds that there is in these phenomena an “Ecstasy of Woe,” distinct from pleasure and pain, pure and simple, and superior to them.
Hartmann, the pessimist philosopher, goes a step farther, and claims that “there is no pleasure which does not contain an element of grief; and no pain without a tinge of pleasure.” This is obviously an exaggeration; for what is the element of anguish that enters into the feelings of a successful lover when he imprints the first kiss on the lips of the girl who has just promised to be his wife? or what the element of pleasure in the feelings of a jealous lover the moment he hears that his rival has won the prize?
