Godfrey-Smith showed octopus and human lineages with a phylogenetic tree. He acknowledges the influence of Daniel Dennett's philosophy. All the photographs of octopuses and cuttlefish were taken underwater by Godfrey-Smith.

It is illustrated with 17 colour plates and monochrome photographs and diagrams in the text. It was first published in the United Kingdom by William Collins in 2017. Other Minds was published by Farrar, Straus, and Giroux in the US in 2016. Peter Godfrey-Smith is an Australian philosopher of science, specialising in the philosophy of mind and its relationship with the philosophy of biology. His octopus subjects come across as "uncannily personable without being at all human." Book Context The book has been admired by reviewers, who have found it delightfully written, undogmatic but incisive in its analysis, and its account of intelligence as a subjective embodied experience elegantly told.

The book reflects on the nature of cephalopod intelligence in particular, constrained by their short lifespan, and embodied in large part in their partly autonomous arms which contain more nerve cells than their brains.

Complex active bodies that enable and perhaps require a measure of intelligence have evolved three times, in arthropods, cephalopods, and vertebrates. It compares the situation in cephalopods, especially octopuses and cuttlefish, with that in mammals and birds. Other Minds is a 2016 bestseller by Peter Godfrey-Smith on the evolution and nature of consciousness.
