Where lies the boundary between fantasy and reality? How can we distinguish dream from delirium, illusion from wish, hallucination from discernment? How can we explore or imagine what takes place elsewhere? The exhibition covers two centuries, starting from the many questions concerning psychosis, hallucination and illusion. Not to give a classic historic account, but to elucidate five unique oeuvres from this period that balance between art, knowledge and science. J.J. Grandville, Gustav Mesmer, Gerard Heymans, Jean Perdrizet and Mathew Kneebone each created or mapped out a different universe, thus trying to grasp the ungraspable in their own way. These are worlds in which pencils walk, bicycles float, the distance between two parallel lines is variable, typewriters are in contact with the deceased and street lamps stop shining when you walk past them. Another World creates passages: from this one to the other, between the other worlds among themselves, and perhaps also from the other world back to this one.
