It is this ever increasing peremptory demand for erotic completeness of the woman of developed individuality of the present time, which causes her always to wish to more fervently cherish the personality of the man as entirely as it is her happiness and her pride to be able to give her own. It is this demand for entirety which, among Germanic peoples, at least, makes woman neither desirous nor psychologically fitted for the so-called "free love." This is evidently to be concluded from the vicissitudes of those who have tried it. "Free love" is moreover quite as senseless an expression as "legal love." Because no external command can call love into being or repress it; it is in this sense always free, yet as are all feelings, it is bound by certain psychological laws. If not, then it does not deserve the name of love. It is with love as with the human face: though the individual varieties are infinite, yet there are certain general characteristic features which make all these different faces human faces, all these different feelings human love. And in every time there is a type for both, which is recognized as nobler than the others. This noblest type of love has been portrayed by a Danish writer,[A] who endeavored to show that a conception of life founded upon evolution need not lead to laxity in sexual relations. He shows how the erotic feeling, as all other feelings, has been developed from an incoherent, indeterminate and indefinite condition to one more coherent, determinate and differentiated, and so from a simple instinct for reproduction of the species has been finally transformed to an entirely personal, inner love. The highest type of this love is that which exists between a man and a woman of the same moral and intellectual level; which demands of necessity reciprocal love in order to be perfected, and can therefore be contented with no other kind of reciprocal love than a corresponding erotic love. This perfect love includes the yearning desire of both lovers to become entirely one being, to free each other and to develop each other to the greatest perfection. If love is perfected and consummated thus by the life together, then can it be given to only one and only once in a lifetime. This thought of the Danish writer is expressed with the concise brevity of the poet, by Bjornson, when he says of the sensation "feeling oneself doubled" in the beloved one: "_That_ is love, all else is not love." This feeling which liberates, conserves and deepens the personality, which is the inspiration to noble deeds and works of genius, is the opposite of the ephemeral, merely sensual love, which enslaves, dissipates and lessens the personality.
