I never attempted to incorporate a real story into my books, I never wrote the so-called "political fiction" since I strongly believe that no political events can be foreseen - regardless whether on the global or on the local scale.
In this book I tried to imagine and describe a psychical situation of a human being whose cerebral hemispheres have been separated (callotomy). I was fascinated by the situation in which each hemisphere could possess a separate consciousness. Before I started writing I spent a long time studying scientific literature - I allowed myself to invent certain things, however about eighty percent of what I wrote was directly based on scientific data. The rest was my own "supplement" that was necessary because of considerations related to the development of the story.
