The question of identity is at the heart of this third number of GTK. All of the contributions in these pages refer continually back to one of the unresolved questions of our time – the great theme of the ‘who’. It is as if today we radically experience a different existential priority compared to the past. Ultimately, almost two thousand years of western civilisation have revolved around questions of the ‘what’ and the ‘why’, around the essence and the meaning of reality. Progressively (and laboriously), the most mature modernity has begun to move the focus of interest towards context and process, towards the ‘how’ things happen, towards the ‘when’ and ‘where’ and towards ‘how’ relationships between beings occur.
