ABSTRACT
This conclusion presents some closing thoughts on the concepts discussed in the preceding chapters of this book. The book describes that the connections between the properties that create the cluster of properties upon which human nature supervenes according to the cluster theory is a contingent one. A major advantage of the cluster theory of human nature thus is that it captures and explains many common expressions in ordinary language and many distinctions embedded in common sense. The book considers the impact of the variations in the species-sense and species-orientation in individuals who are biologically human caused by disease, injury, and/or developmental abnormalities and the similarities and differences between such individuals and non-human animals provides some additional conceptual purchase on the notion of human nature. It provides the most complete understanding of that presently existing human nature to date. Human nature emerges and ascends from the properties occurring in the natural world.
