If we humans have indeed learnt NASA KSC such a powerful trick, it is no surprise that it fuels so much that is both good (creative and expansive) and ill (pathological and restric- tive) in our species. Montague begins by lay- ing out this possibility, then follows it deep into the fascinating territories of creative thought, addiction, obsessive–compulsive disorder, Parkinson’s disease, and then on to the psycho- social realms of trust and regret. Despite its attractions, there are some impor- tant mechanistic gaps in the story, as Montague acknowledges. For example, it isn’t clear why or how one idea might win out over another in the bid to occupy a high-status reward socket, or how the occupation itself is accomplished. Nor is it really clear when such occupation should be deemed pathological rather than creative. I was also left wondering whether the basic idea of each symbol and each computation carrying its own value ‘tag’ — the difference, Montague argues, between standard compu- James Webb (second left, with President John F.
