Abstract
Chapter 20 of Plotinus’ treatise VI, 2 [43] has received particular attention because it seems to deal with the Intellect. However, the connection of this chapter with chapter 19 is problematic insofar as the latter deals with the ways in which species are generated by the first genera. Our aim will be to show that chapter 20 can only be understood in the light of the notion of genus. More precisely, Plotinus’ aim in this chapter is to demonstrate the priority of the genus over its species by means of the theory of double activity. In order to demonstrate this point, the notion of Intellect is introduced by Plotinus as a model (παράδειγμα) to conceive this priority. We will study successively these two chapters to justify this point, insisting on the link between them as well as on the reinterpretation of some key Aristotelian concepts. This study also shows that the use of the comparison with science allows Plotinus to justify the primacy of the intelligible totalities that are the Soul and the Intellect as well as the generation of their respective parts, the particular souls and the particular intellects.
