Abstract
The problem of legitimacy of metaphysical knowledge is examined in the paper in connection with the antimetaphysical fervor of philosophy of postmodern, tendencies to “escape from ontology”, and deep crisis of humanities. The conceptual analysis of fundamental grounds of traditional metaphysics is conducted as a method of localization and orientation in space. The metaphysical systems of separate historical epochs are based on certain spatial metaphors: circle, cross, system of co-ordinates, surface. As an alternative practices a deconstruction offers fundamental ontology of Martin Heidegger which is focused on time as organizing principle of the universe. There is a task to proof a necessity and productivity of metaphysics as sciences and as a method of cognition.
