Very various views have prevailed on the question how many human beings it is legitimate for one human being to employ for his exclusive sexual gratification, and among different nations, and at various times, the most widely divergent rules and regulations have prevailed regarding the mode of sexual possession, and, on the other hand, regarding the duties towards this sexual property; but wherever marriage has existed, it has signified a right of property in respect of sexual utilization. If we oppose marriage, =we mean that we oppose that which actually constitutes marriage according to morality, and according to written law, that which even the most enthusiastic advocates of this institution regard as so debasing that they are ashamed to name it openly=. But, with the exception of the matters relating to sexual service, =we hold fast to and defend everything which is publicly considered as marriage=, and we expect that in this case we shall be “=faithful=,” “=constant=,” and “=trustworthy=” in all circumstances. For, according to our view, these most important imponderabilia, and these intimate associations of interest between husband and wife, are not the inevitable result of the longing for physical enjoyment in common, but are the much-to-be-desired result of a well-considered longing for any one or all of the relations entering into the question. According to our view, however, the duration of this union, and constancy while it lasted, would not be dependent upon the activity of sexual desires. A special =Association for Sexual Reform= was founded in Berlin in the year 1906, at the instance of the editor of the _Die Schönheit_, Karl Vanselow. It is an Association of cultured men and women who also have in view the formation of local groups, and the delivery of artistic and scientific lectures in furtherance of their movement for reform. In the above-mentioned monthly magazine, _Mutterschutz_, edited by Helene Stöcker, all the modern problems of love, marriage, friendship, parentage, prostitution, and all the associated problems of morality, and of the entire sexual life, are discussed from their philosophical, historical, legal, medical, social, and ethical aspects. The editor herself, a talented disciple of Nietzsche, has since the year 1893 been chiefly occupied in the study of the psychological and ethical aspects of the problems of higher love, and has recently published her collected writings on this subject in a single volume.[207]
