Einheit und Vielheit als metaphysisches Problem

Metaphysics sees itself as a theory of reality: In comparison to everything which presents itself to our senses or our everyday common sense as real, metaphysics would like to teach us, giving reasons, what it actually means to be real, how reality is constructed and what its fundamental structures are. In order to do so, in its classic form it is based on a first or a principle. This volume focuses on the dual terms of unity and plurality, which are pivotal for a principle-oriented metaphysics. Is all reality based on the one, or are plurality and otherness irresolvable? Does the logic of unity merely create a dialectic illusion? Or can unity be seen in a way which justifies plurality? The authors of the articles in this volume cover the main stations of the history of metaphysics, ranging from Parmenides to Lévinas.
