[Footnote 152: Freud, _Die Traumdeutung_, p. 66. This work, published in 1900, is the chief and most extensive statement of Freud's views. A shorter statement is embodied in a little volume of the 'Grenzfrägen' Series, _Ueber den Traum_, 1901. A brief exposition of Freud's position is given by Dr. A. Maeder of Zurich in 'Essai d'Interpretation de Quelques Rêves,' _Archives de Psychologie_, April 1907; as also by Ernest Jones ('Freud's Theory of Dreams,' _Review of Neurology and Psychiatry_, March 1910, and _American Journal of Psychology_, April 1910). For Freud's general psychological doctrine, see Brill's translation of 'Freud's Selected Papers on Hysteria,' 1909. There have been many serious criticisms of Freud's methods. As an example of such criticism, accompanying an exposition of the methods, reference may be made to Max Isserlin's 'Die Psychoanalytische Methode Freuds,' _Zeitschrift für die Gesamte Neurologie und Psychiatrie_, Bd. 1. Heft i. 1910. A judicious and qualified criticism of Freud's psychotherapeutic methods is given by Löwenfeld ('Zum gegenwärtigen Stande der Psychotherapeutie,' _Münchener medizinische Wochenschrift_, Nos. 3 and 4, 1910).] [Footnote 153: I have set forth Freud's views of hysteria, now regarded as almost epoch-making in character, in _Studies of the Psychology of Sex_, vol. i. 3rd ed. pp. 219 _et seq._] [Footnote 154: This is supported by the fact that in waking reverie, or day-dreams, wishes are obviously the motor force in building up visionary structures. Freud attaches great importance to reverie, for he considers that it furnishes the key to the comprehension of dreams (_e.g._ _Sammlung Kleiner Schriften zur Neurosenlehre_, 2nd series, pp. 138 _et seq._, 197 _et seq._). But it must be remembered that day-dreaming is not real dreaming, which takes place under altogether different physiological conditions, although it may quite fairly be claimed that day-dreaming represents a state intermediate between ordinary waking consciousness and consciousness during sleep.] [Footnote 155: The special characteristics of dreaming in the hysterical were studied, before Freud turned his attention to the question, by Sante de Sanctis (_I Sogni e il Sonno nell' Isterismo_, 1896).
