Abstract
If the task of a post-Cartesian psychoanalysis is understood as one of exploring the patterns of emotional experience that organize subjective life, one can recognize that this task is pursued within a framework of delimiting assumptions concerning the ontology of the person. In this paper, we discuss these assumptions as they have emerged in the thinking of four major philosophers on whom we have drawn: Søren Kierkegaard, Friedrich Nietzsche, Ludwig Wittgenstein, and Martin Heidegger. Our purpose in what follows is to describe essential ideas of these various thinkers and to identify the formative personal contexts within which their key insights into human life took form. By psychologically contextualizing philosophical assumptions, we hope to make progress toward discerning the particularization of scope that may be associated with these assumptions, and hence to begin a further opening up of the horizons of understanding that inevitably encircle psychoanalytic inquiry.
