“There must be some deep-rooted anti-social principle in every man's nature, so dearly does he love aught that separates him from his kind; or is it but one of the many shapes taken by that mental kaleidoscope, vanity, the varying and the glittering, the desire of distinction, sinking into that of notice?”

On Kippis; Gregory’s Life of Hall, reported in Bartlett's Familiar Quotations, 10th ed. (1919).

The portion of this statement, "Love is the only sane and satisfactory answer to the problem of human existence" has been widely quoted alone, resulting in a less reserved expression, and sometimes the portion following it has been as well: "Any society which excludes, relatively, the development of love, must in the long run perish of its own contradiction with the basic necessities of human nature."
The Art of Loving (1956)
Context: Our society is run by a managerial bureaucracy, by professional politicians; people are motivated by mass suggestion, their aim is producing more and consuming more, as purposes in themselves. All activities are subordinated to economic goals, means have become ends; man is an automaton — well fed, well clad, but without any ultimate concern for that which is his peculiarly human quality and function. If man is to be able to love, he must be put in his supreme place. The economic machine must serve him, rather than he serve it. He must be enabled to share experience, to share work, rather than, at best, share in profits. Society must be organized in such a way that man's social, loving nature is not separated from his social existence, but becomes one with it. If it is true, as I have tried to show, that love is the only sane and satisfactory answer to the problem of human existence, then any society which excludes, relatively, the development of love, must in the long run perish of its own contradiction with the basic necessities of human nature. <!-- p. 111 - 112

Celui qui ignore à quel point la fortune variable et la nécessité tiennent toute âme humaine sous leur dépendance ne peut pas regarder comme des semblables ni aimer comme soi-même ceux que le hasard a séparés de lui par un abîme. La diversité des contraintes qui pèsent sur les hommes fait naître l'illusion qu'il y a parmi eux des espèces distinctes qui ne peuvent communiquer.
