This is an excellent account of various closely related concepts in modern computational neuroscience, communicating to non-mathematical readers key theories such as predictive error signals and the dopamine system, temporal difference theory, cognitive control, neuroeconomics etc, testable in humans using behavioural and neuroimaging methods. As a philosopher observed, this approach hog-ties old philosophical dogmas. Indeed its a valuable antidote to philosophy, and unlike millennia of philosophical effort (including Satre), this approach is making very active progress. Highly recommended.
