Georgios Tsagdis


Dr. G. Tsagdis
+31 71 527 2727

I work across theoretical and disciplinary intersections drawing on 20th Century, Contemporary and Ancient Greek Philosophy. I believe in the need of contemporary philosophy to engage with the full spectrum of its history and open up beyond the confines of academia, reaching, motivating and inspiring a wider public. I believe that teaching should be a process of co-creation.

Fields of interest 

  • Continental Philosophy
  • Ancient Greek Philosophy
  • Platonism & Neo-Platonism
  • Philosophy of Technology
  • Philosophy of Science
  • Political Philosophy
  • Aesthetics


I come from a diverse educational background and I carry over this breadth of interest to my research and teaching. At the same time, in all my work, I maintain a rigorously philosophical approach.

I am particularly interested in notions of nothingness in the history of philosophy (e.g. negativity, privation, apophatism, absence, etc.). I have a keen interest in the core philosophical categories of time and space, as well as in the notion of matter. I am further interested in exploring how the concept of matter intersects with that of nothingness in the history of philosophy.

At the same time, I believe that work in ontology and metaphysics cannot but extend to questions of practice, with which it is intertwined. Not only science and technology, but also ethics and politics are integral in determining the scope and the significance of questions such as those on nothingness and materiality.
