ABSTRACT
The species-orientation for members of a particular species covers the range of ways in which the members of that species are able to act upon and be acted upon by their environment. Biologists and social scientists often make a sharp distinction between the biological and cultural contributions to human nature and then argue the relative importance of each. Human society and human culture are obviously usually counted on the culture side of such an equation. The cluster theory of human nature thus considers the biological and cultural influences upon human nature simply to occupy different positions on the same continuum and not to be qualitatively different from one another. The important aspect of human language to emphasize is the way in which its development and uses were and still are essentially social. Species-haecceity is presented to human beings in various ways, but no way is more central or important than through the use of human language.
