Where does reality end and fantasy begin? When can we talk about an hallucination? How do we bridge the gap between our world and others, and imagine or research what is happening 'elsewhere'? Another World opens the gateway to alternative realities. It shows how science and art have explored the unknown areas of the mind for the last two centuries. As innovative as it is offbeat, this story begins with selections from the oeuvres of four amazing creative thinkers, each of whom have generated a different world. From walking pencils to flying bicycles, materialised ghosts and optical illusions, nothing is too odd for this book and its curious insights into the human mind. Text in English, French, and Dutch.
