Raymond; or, Life and Death is Sir Oliver Lodge's deeply personal and philosophical examination of life beyond physical death. Written following the death of his son Raymond during World War I, Lodge documents his experiences, observations, and investigations into spiritual communication and psychical phenomena.

Combining personal testimony with scientific curiosity, the book explores questions surrounding consciousness, survival after death, communication with the departed, and the possibility of a continued existence beyond the physical world. Lodge approaches these subjects from the perspective of a scientist and investigator, making the work an important historical contribution to the literature of spiritualism and psychical research.
