Whilst Freud's psychology has for its predominant note the centrifugal tendency, which demands its happiness and satisfaction in the objective world, in that of Adler the chief _rôle_ belongs to the centripetal movement, which tends to the supremacy of the subject, to his triumph and his liberty, as opposed to the overwhelming forces of existence. The expedient to which the type described by Freud has recourse is "infantile transference," by means of which he projects phantasy into the object and finds a compensation for the difficulties of life in this transfiguration. In the type described by Adler what is characteristic is, on the contrary, the "virile protest," personal resistance, the efficacious safeguard which the individual provides for himself, in affirming and stubbornly enclosing himself in his dominating ideas. The difficult task of elaborating a psychology which should pay equal attention to the two types of mentality belongs to the future.

It is capable of transformation from one form to another. The metamorphosis can be sudden, as when one function replaces another in a moment of danger; or it can be gradual, as we see it in the process of sublimation, where the libido is led over a long and difficult path through a variety of forms into a different function."--MARY MOLTZER.] [Footnote 185: "Pragmatism," Chapter I.] [Footnote 186: "Pragmatism," ch. i., p. 14.] [Footnote 187: W.

Its mode of genesis is in itself sufficient to isolate a dream from the other contents of the conscious, for it is a survival of a peculiar psychic activity which takes place during sleep, and does not originate in the manifest and clearly logical and emotional continuity of the event experienced.
