Abstract

In an entry of Papirer, located between the years 1842-1843 (IV C 100), entitled "On the concepts of Esse and Inter-Esse," Kierkegaard makes a fundamental methodological assertion: the various sciences should be ordered and built through the accent put on being (Vaeren - Esse). Thus, the ontology and mathematics, because they develop from a ground of elemental unity between thought and being, are a particular kind of science with epistemological well-defined characteristics. However, as Kierkegaard shows in Postscript, the same plea can not be relied on what is named Inter-Esse. Thus, this paper aims to outline the general features of the concept of Inter-Esse as well as their connections with what, in that same entry, Kierkegaard calls "Existential Science" (Existentiel-videnskab).
