In A Foot in the River, best-selling historian Felipe Fernandez-Armesto sifts through the evidence and offers some radical answers to these very big questions about the human species and its history - and speculates on what these answers might mean for our future. Combining insights from a huge range of disciplines, including history, biology, anthropology, archaeology, philosophy, sociology, ethology, zoology, primatology, psychology, linguistics, the cognitive sciences, and even business studies, he argues that culture is exempt from evolution. Ultimately, no environmental conditions, no genetic legacy, no predictable patterns, no scientific laws determine our behaviour. We can consequently make and remake our world in the freedom of unconstrained imaginations.
