Since time immemorial, hwnan beings have sought to understand theessence of human nature. One well-known explanation-human nature isdualistic, body and soul, and composed of organic and spiritual dimensions-has not ended the debate over subissues that proceed from the mainconcept of hwnan nature. Our concern here is how the spirit and the bodyinfluence each other. As modem knowledge and science are far from havingthe last word in this domain, the perplexity of human nature continuesto engage the attention of philosophers, psychologists, sociologists, and scientists.In real terms, nothing has changed in our dualistic human natureexcept its labeled names.In general, modem psychologists have come to see the dualism ofhuman nature in its innate/learned dimensions. Some modem philosophershave stuck by the asserted dualism of hwnan nature, making only slightmodifications concerning its spirit/body duality. For them, human natureconsists of a body/mind dualism.'

Behavioral psychologistshave sought to eliminate entirely, or at least as much as possible, the innatestate (the inner, spiritual dimension) of our dualistic human nature, with theresult that they view the latter as no more than a mere reflection of theexternal environment(s). In a similar manner, the French sociologist EmileDurkheim has oriented his own sociology toward the concept of /es fairssociau.x, which he believed to be the only forces that one needed to considerwhen explaining human behavior. His resulting perspective bears astrong resemblance to behaviorism, for both desire to eliminate the innate,the psychological, and the spiritual side of human nature.Contrary to Durkheim's rigid social determinism and behaviorism'snarrow S-R, sociologists have emphasized the importance of humannature's innate biogenetic2 factors and how they shape and determinehuman behavior. For them, the social behavior of human and nonhumanliving beings can be explained by biogenetic determinants. For example,the practice of not marrying one's very close relatives can be seen as a result ...
