Empiricism and introspectionism
Explanation
Empiricism and introspectionism are epistemological and psychological traditions that emphasise direct, subjectively accessible experience as the primary source of knowledge about consciousness. They have roots in British philosophical empiricism (Locke, Berkeley, Hume, Mill) and developed as a systematic psychological programme in the second half of the nineteenth century, with Wilhelm Wundt (1832-1920) as the central figure in the first laboratory of experimental psychology (Leipzig, 1879).
Wundt conceived psychology as the science of immediate experience, accessible by experimental introspection (experimentelle Selbstbeobachtung): trained subjects reported their conscious states under controlled conditions (controlled stimuli, specific tasks, chronoscope to measure reaction times). The aim was to analyse consciousness into its basic elements: sensations, feelings, images, following a programme Wundt called physiological psychology, combining introspection with sensory physiology.
Edward Titchener (1867-1927), Wundt's disciple who took these ideas to the USA (Cornell University), developed structuralism: seeking the basic structural elements of consciousness through systematic introspection. Observers trained in the structuralist method had to describe the pure content of their consciousness avoiding the stimulus error (describing the object instead of the experiential content). Titchener produced detailed catalogues of elementary sensations across various modalities.
In parallel, the Würzburg school (Oswald Külpe and disciples such as Karl Bühler, Narziss Ach) developed an introspection oriented to higher thought. They discovered the existence of imageless thought, questioning the associationist thesis that all thought reduces to combinations of sensory images. This generated the famous imageless thought controversy with Wundt and Titchener.
Introspectionism entered into crisis with the advent of behaviourism (Watson, 1913: Psychology as the Behaviorist Views It) which rejected introspection as unscientific (not intersubjective, not replicable, prone to bias) and proposed that psychology should deal only with observable behaviour. For decades (approximately 1920-1960), Anglo-Saxon academic psychology virtually excluded consciousness from its object of study. Europe maintained different traditions (Gestalt, phenomenology, psychoanalysis).
For the theory of consciousness, classical introspectionism left an important legacy even if its limitations are known. Its contributions: the conviction that conscious phenomena are real data, rigorously studyable (an idea recovered today as Varela's neurophenomenology); catalogues of experiential phenomena that cognitive psychology and contemporary phenomenology re-examine; experimental methodologies still in force (reaction times, psychophysics, etc.). Orthodox behaviourism was superseded by the cognitive revolution (from 1960), which rehabilitated internal mental processes as objects of study, although with methods more indirect than classical introspection. Today, with contemporary consciousness science (Chalmers, Dennett, Tononi, Varela), attention is returning to direct phenomenological data, with trained techniques (Petitmengin's microphenomenology, contemplative research) that update and refine the introspectionist project. Empirical introspection, properly refined, remains one of the essential routes to the scientific study of consciousness.
