“All concur that free society is a failure. We slaveholders say you must recur to domestic slavery, the oldest, the best and most common form of Socialism. The new schools of Socialism promise something better, but admit, to obtain that something, they must first destroy and eradicate man’s human nature.”

I've often thought: Why is it that you can get a great nation like America marching, fighting, sacrificing, and dying in the struggle to destroy the master race theory in Berlin, and people haven't got an ounce of courage to fight against the master race theory in America? We need the same sense of dedication, the same courage, and the same determination to fight the immorality of segregation and racial bigotry in America as we did in the battlefields against Hitlersim.

Context: We must not only seek to change the moral characters of individuals, we must make an intelligent and strenuous effort to change the present social system. Thought and energy must be devoted to the eradicating of all elements of our present system that are anti-social and unchristian...

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
