PHILOSOPHICAL PEEIODICALS. 585* but still equivocal as regards form, does the inadequacy of the idea of form suffer change, according as the one or the other of the forms pre- sented by the complex is apprehended so that this variation of inade- quacy may be referred to the formation of the idea of the different forms,, as to the sole variable factor in the case ? By means of experiments- (inter alia, upon the Mueller-Lyer figure), the writer is able to answer this question in the affirmative.] Literaturbericht. KANT-STUDIEN. Bd. xi., Heft 2, June 1906. Bruno Bauch. ' Cham- berlains Kant.' [A severe criticism of this recent work.] P. Hauck. ' Die Entstehung der Kantischen Urteilstafel.'

' Uber Begriffe, Definitionen und rnathematische Phantasie ' (Schluss). Viktor Stern. 'Ein neues Argu- ment gegen den Materialismus.'

Materialism justified by all other psychical processes, but refuted by the existence of that which cannot be inherited, viz., knowledge.] Emil Bullaty. ' Erkenntnistheorie und Psychologic.'" [A long instalment of an article critical at once of Formalism and Psycho- logisrn. Experience free from assumption reveals itself immediately as- a consciousness and a world of phenomena forming, not the goal, but the starting point of epistemological and psychological investigation. Con- sciousness itself is free from all assumption, and in it must be found the motives for the assumption of inner and outer, subject and object. To- assume for consciousness itself motives created from it perverts the fundamental facts.] Berthold Weiss. 'Lamprechts Geschichtsphilo- sophie.'
