In the background of Mary Shelley’s life was a very public debate between two prominent doctors beginning in 1815: John Abernethy and William Lawrence, both faculty at the Royal College of Surgeons. Lawrence was Shelley’s doctor. There was a clash in their philosophies that emerged in public lectures. Abernethy’s belief about life is more harmonious with Judeo-Christian faith: that there is an essence that renders organic matter different from the inorganic and that human life is fundamentally different from other life. Lawrence maintained that life is simply matter that has grown sophisticated enough to reproduce itself and to become aware of its surroundings. Lawrence paid for this by losing his job. Ruston implies that Shelley’s Frankenstein subscribes to Abernethy’s belief.
