German Fascism was not limited to a movement of a sole class or group. It required the support of broad social strata (cf, Table I). But as it well-known, of these strata the core element was the lower middle class. We must grasp this class in its dynamic aspect as it were, i. e. not as fixed in quality and quantity, but rather as including the shift of its constituent elements, and so mainly concern ourselves with the phenomena of loss of status. The author considers Fascism as a manifestation of the intense desire for power concentration and monopoly in order to remedy the broad frustration suffered by those who have experienced a loss in status (the declassé). In Germany the core of them, the vanguard of Nazis were the demobilized officers' groups, Provoking the Kapp Putch, they organized a number of conspiratory military bands in country, and toppled the leaders of the government one after another. Afterwards these groups absobed petit bourgeois elements who had multiplied from 1895 to 1925 (cf. Table II), or unemployed masses who numbered more than 6, 000, 000 in the depression period. These groups became the reservoir of the nazi mass organization, Seen from the psycho-behavioral point of view, these movements were the counter-historic ones based-on the infinitely negative drive which had the denial, of all values under imperial Germany as a premise. The reason why Nazis displayed the brutalities, such as the conducts of the SS guards in concentration camps were (1) the gratification of their human needs in a most unhuman ways and (2) the dissolution of their feelings of inpotency by the destruction of the immediate objects, which resulted from the fear of the decline and decay of their former status or class positions. But in fact it meant the emergence of the limitless cycle of causality of fear-terrornew and greater fear. In this case, considering the fact that the people suffered from the fear adhered to the power mechanism, the state power was strengthened through the organization of them and the new fear was engendered by the stregthened power organization. As to the Nazi ideology, it emerged after (1) the decline of the mediaeval and authoritarian values under the second imperial regime and (2) toppling of the liberalistic values in the Weimar Republic by chauvinism. Such an attitude denying all values was reflected on the ideological plane. The anti-aristocratic and anti-traditional temperament made the Nazi ideol. ogy a emotional and random aggregate full of contradictions. It was beyond the design of the Nazi leaders. It may be said that the success of Nazis wasin this sense due.to a sort of selfsuggested process on the part of the people which served to deceive themselves by a trick utilized by a part of them.
