Eros is a superhuman power which, like nature herself, allows itself to be conquered and exploited as though it were impotent. But triumph over nature is dearly paid for.
Nature requires no explanations of principle, but asks only for tolerance and wise measure.
We shall never get the better of him, or only to our own hurt. He is not the whole of our inward nature, though he is at least one of its essential aspects. The persona, the ideal picture of a man as he should be, is inwardly compensated by feminine weakness, and as the individual outwardly plays the strong man, so he becomes inwardly a woman, i.e., the anima, for it is the anima that reacts to the persona. But because the inner world is dark and invisible to the extraverted consciousness, and because a man is all the less capable of conceiving his weaknesses the more he is identified with the persona, the persona's counterpart, the anima, remains completely in the dark and is at once projected, so that our hero comes under the heel of his wife's slipper. If this results in a considerable increase of her power, she will acquit herself none too well.
