A colleague commented that it is difficult to give a clear brief summary of Eccentric Existence because it has so many moving parts. That's fair, and for that reason Tom Greggs offers not a précis but, as he says, a ‘tour’ of EE. I am grateful to him for this perceptive, perspicuous and generous tour of the book's premises and conclusions. I want to address as best I can here Greggs's several ‘unsystematic probes’. The probes seem to me to fall into two broad groups, one raising formal or methodological concerns and the other substantive concerns. I shall begin with the first group, taking them up in more or less the order in which they were made.
