In Propelled, Elpidorou persuasively argues that the three prima facie undesirable conditions of boredom, frustration and anticipation are, in fact, importantly valuable to human life. His method is an interesting combination of existentialist explorations and reporting of cognitive science research, all written in a style more friendly to the analytic-philosophical tradition. However, I argue, the book’s precision and depth of philosophical analysis have some limitations. This is so in two main respects: first, in the relative lack of discussion of important (...) philosophical antecedents, and secondly, in the relative lack of critical engagement with some of the empirical literature the book discusses.
