In the ancient times of incomplete personalities, monogamy was impossible; but since the coming of Christ completed personality has been presented to our view and we have become incapable of bigamous love. Yet, naturally, as I have just stated, the principle of monogamy breaks down if there is more or less of abnormality in the character.
Quite recently, in many parts of Japan, lovers, finding this whole-souled love unattainable, have sacrificed themselves; and there are certain thinkers who dispute the eternal validity of the principle of monogamy, regarding these cases as disproof of it.
However, I think quite otherwise, for in situations where lovers attain control over their environment, mastery of their passions, and consciousness of true human nature, their character union will, in any period whatever, be recognized necessarily as valid, and therein a perfect monogamy is realized. I therefore do not say, add one and one, and arrive at unity, but rather, that that which is essentially one cannot be divided into two. The two souls aflame will be perennially ardent. This is what I term monogamy.
Man's Degeneracy
When desire is separated from love and from marriage, it becomes that divisive love which is real lust, that which draws men's lives down to the horrible bottom of hell. For example, a man who upon marrying makes lust his sole aim, no matter who his mate may be, descends along the way of least resistance, so long as he can satisfy his own lust. He cares not a whit what the character of his mate may be or how society regards his conduct. He lives solely to indulge his own selfish desire, and is a mere slave to mean, mechanical instincts. Marriage to such a man is a sort of private prostitution: when he tires of his wife or the prostitute with whom he is familiar, his lust demands new means of satisfaction. He is reduced to seeking for more stimulating, defiling practices.
