New in paperback. Hardcover was published in 2024. Jeutner argues that the reasonable person is, at heart, an empathetic perspective-taking device, by tracing the standard of the reasonable person across time, legal fields and countries. Beginning with a review of imaginary legal figures in the legal systems of ancient Egypt, Greece, and Rome, the book explains why the common law's reasonable person emerged amidst the British industrialisation under the influence of Scottish Enlightenment thinking.
