From Wolff to Behaviorism, ed. by Chiara Russo Krauss and Giuseppe Guastamacchia"},"content":{"rendered":"

Psychophysics represents one of the most ambitious and controversial ventures of modern thought. Emerging from the problematic legacy of Cartesian dualism between res cogitans<\/em> and res extensa<\/em>, the idea of an exact science of the soul has been the subject of various and authoritative attempts at a foundation, oriented towards formulating laws capable of explaining the dynamics of psychic events based on a presumed analogy with external events. These efforts found an initial rigorous manifestation in the psychometric hypotheses presented by Christian Wolff in his Psychologia empirica<\/em> (1732) and Philosophia practica universalis<\/em> (1738-39), and spanned the whole Enlightenment and nineteenth-century German philosophy, rapidly intertwining with advancements in the fields of physics, optics, and sensory physiology. However, the Enlightenment flourishing of \u201cphysical psychology\u201d encountered an important obstacle with Kant\u2019s denial of the possibility of a mathematical treatment of the soul, as contained in his Metaphysische Anfangsgr\u00fcnde der Naturwissenschaft<\/em> (1786). Kant\u2019s opposition to psychometry was far from unequivocal: on one hand, he assigned empirical psychology to the realm of anthropology, thus not entirely stripping it of epistemic legitimacy; on the other hand, he paved the way for subsequent developments in psychophysics by formulating, already in his Critique of Pure Reason<\/em> (1781), the highly relevant notion of \u201cintensive magnitude\u201d.
\nKant\u2019s interdiction only momentarily delayed the emergence of theories associated with the psychophysical idea, which would emerge systematically during the nineteenth-century German philosophical period. Romantic science \u2013 with authors such as Johann Wilhelm Ritter (1776-1810), Carl Friedrich Kielmeyer (1765-1844), Lorenz Oken (1779-1851), and Karl Friedrich Burdach (1776-1847) \u2013 would undertake the task of reactivating the link between philosophy and physiology, attempting to reconcile the demands introduced by Kantianism with new directions in the study of the living. Shortly thereafter, Herbart\u2019s seminal 1822 lecture to the K\u00f6nigslichen Deutschen Gesellschaft, \u00dcber die M\u00f6glichkeit und Nothwendigkeit, Mathematik auf Psychologie anzuwenden<\/em>, would lay the basis for a mathematical foundation of psychology, thus giving a decisive impulse to the emergence of a true Herbartian psychological tradition represented by Wilhelm Fridolin Volkmann (1801-1877) and Theodor Waitz (1821-1864), alongside figures such as Ludwig Str\u00fcmpell (1812-1899) and Moritz Wilhelm Drobisch (1802-1896). Herbart\u2019s attempt to mathematically quantify conscious events, his critique of Kantian Verm\u00f6genspsychologie<\/em>, and his formulation of the concept of a \u201cthreshold of consciousness\u201d enjoyed considerable success in the philosophical and psychological debates of late nineteenth-century Germany, becoming an indispensable reference for generations of physiologists seeking to establish points of contact between the psychic principle and the perceptual apparatus. In this regard, two traditions can be identified: the first, originating from the laboratory of Johannes von M\u00fcller (1752-1809), with prominent representatives such as Hermann von Helmholtz (1821-1894), Emil Du Bois-Reymond (1818-1896), and Rudolf Virchow (1821-1902); the second centered around the University of Leipzig, with figures such as Ernst Heinrich Weber (1795-1878), Carl Ludwig (1816-1895), Gustav Fechner (1801-1887), and Wilhelm Wundt (1832-1920).
\nFor Helmholtz, it was the physiology of the senses that, as early as in 1855, provided the exact point where philosophy and natural sciences \u201cdraw closer\u201d, defining the contours of that \u201cboundary region\u201d where the two branches of knowledge recognized under the names of Natur-<\/em> and Geisteswissenschaften<\/em> more generally diverge. With Fechner and Wundt, the trajectory of German psychophysics reached its peak. While Fechner, in his Elemente der Psychophysik<\/em> (1860), designated psychophysics as the exact doctrine of the relationships between the soul and the body, having substantiated Weber\u2019s mathematical studies on the connection between stimulus and perception with experimental evidence, Wundt addressed \u2013 almost concurrently \u2013 the issues concerning the measurement of the \u201cmagnitude\u201d of sensations, characterizing this effort in his Vorlesungen \u00fcber Menschen- und Thierseele<\/em> (1863) as the \u201cfirst step in the bold enterprise of applying an exact measure to the magnitudes of what is spirit\u201d. From then on, according to Wundt, psychology was to remain indebted to Fechner for his \u201cfirst exhaustive examination of sensory sensations from a physical perspective, which laid the foundation for an exact theory of sensation\u201d. This marked the scientific foundation of an experimental-based psychology.
\nFechner and Wundt represent the apex of nineteenth-century German philosophical and psychological reflection on the possibility of reconciling the continuous and indivisible interiority of the psyche with the quantitative measurement of partes extra partes<\/em>. The legacy of their scientific insights was carried forward already in the second half of the nineteenth century in other European philosophical contexts: in France by Alfred Binet (1857-1911) and Th\u00e9odore Simon (1873-1961), in Italy by Francesco De Sarlo (1864-1937) and later by Antonio Aliotta (1881-1964), and in the Anglo-Saxon world by Edward Titchener (1867-1927) and the behaviorist theories. Behaviorism, in particular, marked a fundamental departure from Wundtian structuralism by abandoning the problematic framework of Cartesian dualism and introducing the concept of the \u201cobservable manifestations\u201d of the soul. In this context, renewed attempts at the mathematization and formalization of psychology have been made, such as in the studies of Clark Leonard Hull, Mathematico-Deductive Theory of Rote Learning<\/em> (1940) and Principles of Behavior<\/em> (1943). However, this is only one among many twentieth-century developments of psychophysics. The more recent history of this field is far from concluded and remains to be written.

\n1) the modern philosophical presuppositions of the psychophysical idea;
\n2) Wolffian psychometry and the eighteenth-century debate;
