Harry Stack Sullivan is tracing out the developmental history of various forms of personality in his forthcoming volume on _Personal Psychopathology_. [75] Paul Federn commented in his pamphlet that a democratic state must depend upon a democratic family life. [76] See his excellent methodological chapter in _The Psychology of Murder_. [77] _The Origin of the State._ [78] Not to be confused with mind-body parallelism, which is not accepted. [79] Cf. Kelsen, _Der Soziologische und der juristische Staatsbegriff_; “Der Begriff des Staates und die Sozialpsychologie,” _Imago_, VIII (1922), 97-141; “The Conception of the State and Social Psychology,” _International Journal of Psycho-Analysis_, V (1924), 1-38. [80] Perhaps the most important part of the Merriam and Gosnell study of _Non-Voting_ is the symposium of conversational scraps which suggest what balloting actually means to various classes and sections of a modern metropolitan community. [81] Such criticism has been directed against the pioneer venture of the Lynds, _Middletown_. [82] An able discussion of the operational concept is in P. W. Bridgman, _The Logic of Modern Physics_. [83] Alexander and Staub have commented on this in _Der Verbrecher und seine Richter_. But it is principally due to the suspicion of the public officer.
