 Although many such characteristics of proto-Shintō are found in other archaic animistic cultures throughout the world, unlike many of those other locations, in Japan those ancient sensitivities were not suppressed by the imposition of rationalistic philosophies from outside. For example, the expansion of Christianity with its Greco-Roman philosophical analyses drove underground many older animistic cultures (such as the Druids in the British Isles). When the major philosophical traditions from continental Asia entered Japan, by contrast, they did not take an oppositional stance toward the world view already in place within the archipelago. Therefore, much of proto-Shintō’s organicism, vitalism, and the sensitivity to the field of inter-responsive, internal, and holographic relations could survive within the mainstream of Japanese thinking.
