This book divides into two parts. The first is a personal narrative of the impact of the death of the author's son Ralph on him and his family and his efforts to see if there was any evidence for his continued existence (generated largely through visits to mediums) that a thinking person could take seriously. The second is an attempt to evaluate that evidence objectively (based on an extensive survey of current and past scientific research in the UK and the USA). The title reflects the inevitable tension between emotion and intellect in such an enquiry.
