Around 1800, a plethora of epistemological and physiological theories and discoveries contest and differentiate the primacy of “conscious” conceptual synthesis postulated by Kantian transcendental philosophy: Rather than taking the spontaneity of the self-identical subject of the transcendental apperception posited by Kant, as its epistemological point of departure, the aforementioned theories, I argue, implicitly highlight the existence of an unconscious perceptive field, occupying a strangely liminal position between objectivity and subjectivity, between conscious and unconscious processes. This paper will take Salomon Maimon’s critique of Kantian transcendental philosophy in his treatise “Versuch über die Transzendentalphilosophie” (1790) as a point of departure: Maimon, I argue following Gilles Deleuze, is the first to radicalize the consequences of an unconscious, psychic automatism of perception as the constitutive ground of conscious conceptual synthesis. Goethe’s “Theory of Color” (“Zur Farbenlehre”, 1810), especially its first chapter concerning the physiology of color (“Physiologische Farben”), provides, I argue, a physiologically situated theory of vision that further differentiates Maimon’s claim. Goethe’s inquiry into entoptic phenomena discovers a sphere of “pure perceptual events”, i.e., unconscious and physiologically grounded differential mechanisms that precede the synthesis of recognition of clearly delineated figures and objects. Physician Johann Christian Reil, a key-figure in “romantic psychology”, proposes a physiological grounded, proto-“neuronal” theory of mental illnesses and their cure in Rhapsodieen über die Anwendung der psychischen Curmethode auf Geisteszerrüttungen (1803): For Reil, the possibility of mental disorder lies in the very physiological, i.e., neuronal constitution of consciousness. This papers overarching goal is thus to highlight and explicate the philosophical and natural scientific vectors infusing a “differential”, perceptual unconscious, foreshadowing both the psychophysical conception of a “perceptive threshold”, as well as of subsequent psychoanalytical theories of a “Reizschutz”.
