Luria's preoccupation with "Romantic Science" was an idiosyncrasy, or extraneous to the vision of science that animated him from his earliest work to his last. The terms "classical" and "romantic", with regard to certain basic attitudes or orientations to sciences originated with the German scholar Max Verworn, and Luria adopted his terms, and adapted them to his own ends. Luria's own clinical experience, to which he is absolutely faithful, as well as his reading of the great nineteenth-century clinicians, provides an overwhelming demonstration of the opposite danger-the danger of reductionism. Luria sees such reductionism as the very essence of twentieth-century science, at least in medicine, physiology, and psychology. The constructions of physical science, or biology, may be lyrical, but are impersonal and theoretical. The final function of psychoanalysis is to allow "constructions" of human nature, with particular reference to the "psychodynamics" involved.
