Richards commends Skocpol for choosing to focus her book on three revolutions rather than bringing to light a large number of successful and unsuccessful revolutions “in hopes of achieving statistical validity or in the expectation of being able to explain a number of related phenomena.” Like Peter Manicas, Richards also finds Skocpol's refusal to create a general theory for all revolutions commendable. According to Richards, Skocpol “recognizes the limitations of comparative study and the dangers of fitting events into relatively inflexible categories.”
