 Hybridization is a third form of assimilation that leaves neither the original theory nor its opposing rival theory intact. Instead, through their cross-pollination something completely new is born. A hybrid presents us with a new species of philosophy and although we can do a genealogy of its parentage, it cannot (unlike the cases of allocation or relegation) ever return to its earlier opposing forms. If we consider a biological hybrid like a boysenberry, which has a genetic parentage traceable to a loganberry and a raspberry, we cannot find the loganberry or the raspberry intact in the boysenberry. Once the hybrid is created, we cannot undo the crossbreeding; there are now three distinct species of berries. Analogously, in the process of philosophical assimilation, when true philosophical hybrids emerge, historians of philosophy may be able to uncover their genealogies, but the theories themselves can no longer be deconstructed back into their parental origins. As will be explained below, in Japan bushidō, the Way of the warrior, is such a philosophical hybrid born of Confucianism, Buddhism, and Shintō, but which became an independent philosophy of its own that in many ways served as a rival to its antecedents.
