Abstract
The aim of this article is to determine and analyze the meaning of the transitio and the posset that not only enable the radical modal experience of the Amor Dei intellectualis but which are also central features in the attainment of human perfection and of the highest knowledge. I wish to answer the following questions. What power is attributable to the Amor Dei intellectualis? In other words, what is the power that corresponds to human perfection and to the possession of blessedness? And why does Spinoza explain this relation in terms of love? In this article, I intend to give a possible definition of human nature, a definition whose determination implies a maximal affirmation of modal power. At this point more questions arise: by attributing this maximal power to human nature, are we underlining a specific necessity, i.e., a constitutive relation capable of giving a specific form to this power and to human nature? Does the third kind of knowledge imply modifications in human nature itself, e.g., in the body or soul? Finally, does the correlation between the third kind of knowledge and the Amor Dei intellectualis allow for the determination of a model of human nature that surpasses the one given by Spinoza in the preface to part four of the Ethics?
