In attempting to address the heideggerian Seinsfrage, by way of situating it between the platonic conception of ̉όν in the Sophist and of χώρα in the Timaeus, this paper investigates the ontological possibilities that are opened up in terms of rethinking space. Asserting the intrinsic connection between the question of being and that of space, we argue that the maturation of ontology as phenomenology would not unfold in its furthermost potential unless the being of space gets clarified. This state of affairs confronts us with the exacting ontological task to found a theory of space that contributes to an explication of the question of being beyond its associated temporocentric determinations. Consequently, our line of inquiry endeavors herein to constitute a prologmenon to the elucidation of the question of the being of space as “ontokhorology.”

The aim of this paper is to show how the concept of “possible world”, that Husserl inherits from his study of logics, is capital for the understanding of his phenomenology. This concept is a fine tool that provides him a possibility to articulate the question of the physical and the cultural dimensions of some objects. A cultural object as a book or a painting has in fact two dimensions: a “material” one and a “spiritual” one. The author examines which are the relationships between those two dimensions. This question leads him to an interrogation on the genesis of the ideality of the cultural world. Is there not a contradiction between the ideality of the meaning and his historical genesis? In order to provide an answer to this question, the author suggests that one may use the notion of a “linked ideality”, i.e. ideal but linked up to the earth.
