Husserl thus pays homage to Dilthey, and shows himself quite hospitable: first, to the idea of a principle of understanding or of re understanding, of reliving (Nachleben)notions simultaneously to be juxtaposed with the notion of Einfiihlung, borrowed from Lipps and transformed by Husserl, and with the notion of Reaktivierung, which is the active reliving of the past intention of an other mind and the reawakening of a production of meaning in question here is the very possibility of a science of the mind; second, to the idea that there exist totalitarian structures endowed with a unity of internal meaning, spiritual organisms in a sense, cultural worlds all of whose functions and manifestations are solidary and to which Weltanschauungen correspond correlatively; third, to the distinction between physical structures, in which the principle of relationship is external causality, and mental structures, in which the principle of relationship is what Husserl will call motivation.
