There are some human beings--_variants_--who possess hermaphrodite characteristics, usually combining the more or less completely developed organs of one sex with the rudimentary organs of the opposite sex. These hermaphrodite characters are not without their significance--namely, the innate bisexuality of man. While in the normal person, the attributes of one sex are dominant, there are always present in latent form some evidences of the opposite sex. This is no new discovery. In fact the concept of bisexuality is very ancient. Traces of it are to be found in Chinese mythology. The classical Greek mind seems to have had a particular interest in speculating about it. The mythical personification of bisexuality in the Hermaphroditos, the narrative of Aristophanes in the Platonic dialogue, and at a later period the suggestion of a Gnostic sect (Theophites) that primitive man was a “man-woman,” are all based on this presentiment. The first divinities were always bisexual, being either women with a penis or men with a female breast. WHAT BIOLOGY TEACHES US. Lower down in the biological scale--in fact, at the very bottom--we find the _amoeba_, which represents an auto-sexual, or more accurately, a mono-sexual, form. It has all the potentialities for reproduction within itself. By the process of division, first of its nucleus, and then its whole self, it becomes two new individuals. A little further up the evolutionary path, we find the _paramoecium_. At one stage of its career it will divide its nucleus first, and then itself (an autosexual act) similar to the _amoeba_. At another stage it will engage in an elementary sexual act by coming ventrally together with another _paramoecium_, exchange one-half of its nucleus for half the nucleus of the other _paramoecium_, through the mouth, and this process is followed by other nuclear changes, and finally each _paramoecium_ divides itself into two new entities. There is no apparent difference between these primitive little animals. They have no male and female organs, but it is a plausible assumption that the nuclei of each one contains a “male” and “female” portion--something unknown but necessary to procreation. In this instance we have the beginning of bisexuality; but autosexuality is still an essential factor in reproduction. Somewhat higher up the scale we come across the _hydra_, a multicellular animal. Here, also, autosexuality plays a prominent role. The _hydra_ can, without the aid of another, “bud off” a new living _hydra_. Bisexuality is evidenced, however, in the presence of male and female cells which form in the single _hydra_. These unite with one another to produce a new individual in true bisexual manner. In a sense this creature is a combination of the autosexual, bisexual and hermaphrodite.
