One grows tired of thinking, and even of acting; one never grows tired of loving, nor of saying so. In the worst tortures of affection I have never ceased to feel that the essential of happiness is that the heart should be worthily filled--even with pain, yes, even with pain, the bitterest pain." And Sophie Kowalewsky, after intellectual achievements which have placed her among the most distinguished of her sex, pathetically wrote: "Why can no one love me? I could give more than most women, and yet the most insignificant women are loved and I am not." Love, they all seem to say, is the one thing that is supremely worth while. The greatest and most brilliant of the world's intellectual giants, in their moments of final insight, thus reach the habitual level of the humble and almost anonymous persons, cloistered from the world, who wrote _The Imitation of Christ_ or _The Letters of a Portuguese Nun_. And how many others! FOOTNOTES: [45] _Meditationes Piissimæ de Cognitione Humanæ Conditionis_, Migne's _Patrologia_, vol. clxxiv, p. 489, cap. III, "De Dignitate Animæ et Vilitate Corporis." It may be worth while to quote more at length the vigorous language of the original. "Si diligenter consideres quid per os et nares cæterosque corporis meatus egrediatur, vilius sterquilinum numquam vidisti.... Attende, homo, quid fuisti ante ortum, et quid es ab ortu usque ad occasum, atque quid eris post hanc vitam. Profecto fuit quand non eras: postea de vili materia factus, et vilissimo panno involutus, menstruali sanguine in utero materno fuisti nutritus, et tunica tua fuit pellis secundina. Nihil aliud est homo quam sperma fetidum, saccus stercorum, cibus vermium.... Quid superbis, pulvis et cinis, cujus conceptus cula, nasci miseria, vivere poena, mori angustia?"

[47] Dühren (_Neue Forshungen über die Marquis de Sade_, pp. 432 et seq.) shows how the ascetic view of woman's body persisted, for instance, in Schopenhauer and De Sade. [48] In "The Evolution of Modesty," in the first volume of these _Studies_, and again in the fifth volume in discussing urolagnia in the study of "Erotic Symbolism," the mutual reactions of the sexual and excretory centres were fully dealt with.
