There are no doubt important exceptions. Thus Mérimée's famous friendship with Mlle. Jenny Dacquin, enshrined in the Lettres à une Inconnue, was perhaps Platonic throughout on Mérimée's side, Mlle. Dacquin adapting herself to his attitude. Cf. A. Lefebvre, La Célèbre Inconnue de Mérimée, 1908.
The love-letters of all these distinguished persons have been published. Rosa Mayreder (Zur Kritik der Weiblichkeit, pp. 229 et seq.) discusses the question of the humble and absolute manner in which even men of the most masculine and impetuous genius abandon themselves to the inspiration of the beloved woman. The case of the Brownings, who have been termed "the hero and heroine of the most wonderful love-story that the world knows of," is specially notable; (Ellen Key has written of the Brownings from this point of view in Menschen, and reference may be made to an article on the Brownings' love-letters in the Edinburgh Review, April, 1899). It is scarcely necessary to add that an erotic relationship may mean very much to persons of high intellectual ability, even when its issue is not happy; of Mary Wollstonecraft, one of the most intellectually distinguished of women, it may be said that the letters which enshrine her love to the worthless Imlay are among the most passionate and pathetic love-letters in English.
