Wilhelm Wundt (August 1832–August 1920) was a German physiologist, philosopher, and educator who is regarded as one of the founding fathers of contemporary psychology. He was the first person to identify himself as a psychologist.
Wundt revolutionized psychology by advocating for its separation from philosophy and establishing it as an experimental science. Wundt’s early project of scientific psychology created a methodological framework that prioritized empirical evidence over speculation.
His approach emphasized systematic investigation of mental processes through controlled conditions. This marked a significant departure from previous philosophical approaches to understanding the mind.
Wundt proposed that psychology should study conscious experience using experimental methods similar to those in physiology. He developed techniques for analyzing sensory perception, attention, and feeling through careful observation and measurement.
The birth of modern psychology through Wundt’s efforts represented a fundamental shift in how human consciousness was understood and investigated.
Philosophical Underpinnings

Wundt developed voluntarism as a philosophical system that placed the human will at the center of psychological processes. Unlike mechanistic approaches, voluntarism emphasized active mental processes over passive sensation.
The concept positioned human will as the driving force behind consciousness, challenging deterministic views prevalent in his era. Wundt argued that mental life was inherently active and creative rather than merely reactive.
His voluntaristic psychology examined how human will manifests in attention, apperception, and intentional behaviors. This perspective allowed Wundt to explore how individuals actively organize their experiences rather than simply responding to stimuli.
The philosophical foundation of voluntarism provided Wundt with a framework to investigate higher mental processes that were difficult to study through experimental methods alone.
His work shows clear influences from Leibniz, particularly in his conception of the mind as active and creative. The Leibnizian influence appears in Wundt’s understanding of apperception and his approach to psychic causality.
Wundt distinguished between experimental psychology and what he called Völkerpsychologie (cultural or folk psychology), recognizing that some psychological phenomena required philosophical and historical analysis.
Unlike many later psychologists who distanced themselves from philosophy, Wundt insisted on the complementary relationship between the two disciplines. He produced extensive philosophical works alongside his psychological treatises, demonstrating his commitment to maintaining this connection.
General Psychology
Wundt’s most well-known textbook is Grundzüge der physiologischen Psychologie (Main Features of Physiological Psychology), which discusses general psychology. He intended to connect the two sciences.
“Physiology provides information on all phenomena of life that can be perceived using our external senses. In psychology humans examine themselves, as it were, from within and look for the connections between these processes to explain which of them represent this inner observation.”
Wundt believed that physiological psychology had the following task:
“firstly, to investigate those life processes that are centrally located, between external and internal experience, which make it necessary to use both observation methods simultaneously, external and internal, and, secondly, to illuminate and, where possible, determine a total view of human existence from the points of view gained from this investigation,”
he wrote.
“The attribute ‘physiological’ is not saying that it … [physiological psychology] … wants to reduce the psychology to physiology – which I consider impossible – but that it works with physiological, i.e. experimental, tools and, indeed, more so than is usual in other psychology, takes into account the relationship between mental and physical processes.”
After long chapters on the anatomy and physiology of the nervous system, the Grundzüge (1874) has five sections: the mental elements, mental structure, interactions of the mental structure, mental developments, the principles and laws of mental causality.
Through his insistence that mental processes were analysed in their elements, Wundt did not want to create a pure element psychology because the elements should simultaneously be related to one another. He describes the sensory impression with the simple sensory feelings, perceptions and volitional acts connected with them, and he explains dependencies and feedbacks.
Apperception Theory
Wundt challenged the widely accepted association theory, which holds that mental connections (learning) are primarily established by the frequency and intensity of specific activities. His phrase, apperception psychology, indicates that he valued creative conscious activity over elementary association.
Apperception is an emerging action that is arbitrary, selective, imaginative, and comparative. In this process, feelings and ideas are images that are perceptually connected with typical tones of feeling, selected in a variety of ways, analysed, associated, and combined, as well as linked with motor and autonomic functions – not simply processed but also creatively synthesised.
In the integrative process of conscious activity, Wundt perceives an elementary subject activity, i.e. an act of volition, to deliberately move content into consciousness. Insofar as this emergent activity is common to all mental processes, his point of view might be described as voluntaristic.
Wundt considers apperceptive processes as psychologically highly differentiated, and this is largely based on the methodology and findings of his experimental research. One example is a comprehensive series of experiments on the mental chronometry of complex reaction times. In emotions research, specific effects are elicited while a kymograph records pulse and respiration. The observed discrepancies were supposed to help corroborate Wundt’s theory of emotions, which has three dimensions: pleasant- unpleasant, tense – relaxed, excited – depressed.
Psychophysical Parallelism
Wundt, drawing from Leibniz, defined the concept of psychophysical parallelism as follows:
“wherever there are regular relationships between mental and physical phenomena the two are neither identical nor convertible into one another because they are per se incomparable; but they are associated with one another in the way that certain mental processes regularly correspond to certain physical processes or, figuratively expressed, run ‘parallel to one another’.”
The inner experience, while rooted in brain functions, lacks identifiable physical causes for mental changes. Wundt aligns with Leibniz in distinguishing between physical causality, which pertains to the natural processes of neurophysiology, and mental causality, which relates to the processes of consciousness. Both causalities, however, are not opposites in a dualistic metaphysical framework, but rather contingent upon one’s perspective.
Causal explanations in psychology are limited to identifying the effects of antecedent causes without the ability to generate precise predictions. Wundt illustrates the potential inversion in the analysis of cause and effect, as well as ends and means, through the example of volitional acts. He elucidates how causal and teleological explanations can work together to provide a coordinated understanding.
Wundt’s stance contrasted with that of contemporary authors who similarly supported parallelism. He advanced his principles of mental causality, contrasting them with the natural causality of neurophysiology, rather than merely accepting the postulate of parallelism, and established a corresponding methodology. Two fundamentally distinct approaches exist regarding the postulated psychophysical unit, rather than merely two perspectives as suggested by Gustav Theodor Fechner’s identity hypothesis.
Psychological and physiological statements operate within two distinct reference systems. It is crucial to highlight the significant categories to avoid category errors, as articulated by Nicolai Hartmann. Wundt established the inaugural epistemology and methodology of empirical psychology, prior to the existence of the term philosophy of science.
Redefinition of Psychology
Wundt set out to redefine psychology as a broad area that lies between the natural sciences and the humanities, between philosophy and physiology. The scientific theory-based definition of empirical psychology as a psychology of consciousness with its own categories and epistemological tenets replaced the metaphysical definition as a study of the soul.
The task of psychology is to precisely analyse the processes of consciousness, to assess the complex connections, and to find the laws governing such relationships. In his view:
Psychology is not merely a science of the individual soul. Life is a consistent mental and physical process that can be viewed from multiple perspectives to identify overarching principles, especially the psychological-historical and biological principles of development. Wundt emphasized the necessity of comprehending emotional and volitional functions alongside cognitive features, viewing them as equally significant components of the holistic psychophysical process.
Psychology cannot be reduced to physiology. The tools of physiology remain fundamentally insufficient for the task of psychology.
Psychology focuses on conscious processes. Wundt dismissed the inclusion of subconscious mental processes in scientific psychology due to epistemological and methodological considerations. Prior to Sigmund Freud, influential figures such as philosopher Eduard von Hartmann (1901) proposed a metaphysical framework for understanding the unconscious.
Wundt presented two primary objections. He dismissed all psychology based primarily on metaphysical foundations and found no dependable methodological approach. He subsequently revised his initial assumptions regarding unconscious judgments.
When Wundt rejects the assumption of “the unconscious” he is also showing his scepticism regarding Fechner’s theory of the unconscious and Wundt is perhaps even more greatly influenced by the flood of writing at the time on hypnotism and spiritualism. While Freud frequently quoted from Wundt’s work, Wundt remained sceptical about all hypotheses that operated with the concept of “the unconscious”.
Wundt would consider it a misunderstanding to define psychology as a behavioral science in the manner of the later strict behaviorism concept. A variety of behavioral and psychological variables have been observed or measured at the Leipzig laboratory.
Wundt emphasized that physiological effects, such as the changes associated with emotions, served merely as instruments of psychology, similar to the physical measurements of stimulus intensity in psychophysics. Further development of these methodological approaches in a one-sided manner would ultimately result in a behavioral physiology, representing a form of scientific reductionism, rather than contributing to a comprehensive understanding of general psychology and cultural psychology.
Wundt’s concepts were developed during almost 60 years of research and teaching that led him from neurophysiology to psychology and philosophy. The interrelationships between physiology, philosophy, logic, epistemology and ethics are therefore essential for an understanding of Wundt’s psychology.
Cultural Psychology
While Wilhelm Wundt is primarily remembered for establishing the first psychology laboratory, his work on Völkerpsychologie represents a significant but often overlooked contribution to the field. This branch of his research focused on how cultural and social factors influence psychological processes.
Wundt viewed language, mythology, and customs as essential components of collective mental processes that could not be studied through experimental methods alone. He dedicated ten volumes to Völkerpsychologie between 1900 and 1920, examining these cultural elements as products of the human mind.
Language held particular importance in Wundt’s framework, as he considered it the primary medium through which collective thoughts are expressed and transmitted. He analyzed how linguistic structures reflect cognitive processes within communities.
Mythology and religion were examined as expressions of collective imagination and emotional responses to natural phenomena. Wundt traced the development of mythological thinking from primitive animism to organized religious systems.
Customs and social norms were studied as regulatory mechanisms that coordinate social behavior. Wundt believed these practices emerge from collective mental life rather than individual psychology.
Inspired by the ideas of previous thinkers such as Johann Gottfried Herder, Johann Friedrich Herbart, Georg Wilhelm Friedrich Hegel, and Wilhelm von Humboldt (with his ideas about comparative linguistics), psychologist Moritz Lazarus (1851) and linguist Heymann Steinthal founded the Zeitschrift für Völkerpsychologie und Sprachwissenschaft (Journal for Cultural Psychology and Linguistics) in 1860, which gave this field its name. Wundt, in 1888, critically analyzed Lazarus and Steinthal’s disorganized aims and confined the scope of the difficulties by providing a psychologically constructed structure.
The cultural psychology of language, myth, and customs were to be based on the three main areas of general psychology: imagining and thought, feelings, and will (motivation). The numerous mental interrelations and principles were to be researched under the perspective of cultural development. Apperception theory applied equally for general psychology and cultural psychology. Changes in meanings and motives were examined in many lines of development, and there are detailed interpretations based on the emergence principle (creative synthesis), the principle of unintended side-effects (heterogony of ends) and the principle of contrast.
Wundt identified approximately 20 essential dynamic motives in the context of cultural development. Commonly cited motives in cultural development include division of labor, ensoulment, salvation, happiness, production and imitation, child-rearing, artistic drive, welfare, arts and magic, adornment, guilt, punishment, atonement, self-education, play, and revenge.
Additional values and motives arise in the domains of freedom and justice, war and peace, legal frameworks, state structures, and forms of governance. This also pertains to the evolution of a worldview encompassing culture, religion, state, transportation, and a global political and social community.
Religious considerations often intertwine various values and motives, including belief in the soul, immortality, deities, and supernatural entities, alongside ritualistic practices, witchcraft, animism, and totemism. These elements are further integrated with artistic expression, imagination, dance, ecstasy, and social structures related to family and power.
Despite being difficult to translate precisely, Völkerpsychologie encompassed elements of what modern scholars would call social psychology, cultural psychology, and anthropology. Wundt’s approach was remarkably interdisciplinary for his time.
His methodological contributions included historical analysis and comparative approaches to cultural phenomena. Rather than laboratory experiments, Wundt advocated for studying cultural products as expressions of psychological processes.
Modern cultural psychologists have retraced Wundt’s footsteps to rediscover insights that were overlooked during psychology’s subsequent emphasis on behaviorism and experimental methods.
Wundt’s Legacy and Successors
Wilhelm Wundt’s influence extended far beyond his laboratory in Leipzig through his students and the global dissemination of his ideas across multiple continents. His methodological approaches and theoretical frameworks shaped the development of early psychology and continue to influence the field today.
G. Stanley Hall became one of Wundt’s most prominent American students, later founding the American Psychological Association and establishing the first American psychology laboratory at Johns Hopkins University. He embraced Wundt’s experimental approach while adapting it to American pragmatism.
James McKeen Cattell, another influential student, brought Wundt’s methods to Columbia University and pioneered psychometrics and applied psychology. Cattell’s work on mental testing diverged from Wundt’s pure experimental approach but maintained its empirical foundation.
Edward Titchener, perhaps Wundt’s most devoted disciple, established structuralism at Cornell University. However, his interpretation of Wundt’s ideas significantly narrowed the original vision, focusing primarily on introspection while neglecting Wundt’s broader cultural psychology.
Oswald Külpe, initially Wundt’s assistant, later founded the Würzburg School which challenged some of Wundt’s core assumptions about thought processes.
In America, William James developed a competing psychological framework that acknowledged Wundt’s pioneering work in experimental psychology while criticizing its limitations. This creative tension between Wundtian experimental psychology and Jamesian pragmatism shaped early American psychology.
By 1914, over 100 psychology laboratories existed worldwide, most established by Wundt’s former students. These labs adapted his methodologies to local academic contexts while preserving core experimental principles.
Wundt’s ideas spread to Russia through students like Vladimir Bekhterev, to Japan through Yuzero Motora, and across Europe through numerous disciples. Each region modified his approaches to fit local intellectual traditions.
Despite translations often focusing narrowly on his experimental work, Wundt’s comprehensive psychological model combining experimental with cultural psychology eventually gained recognition in broader historical assessments of his contributions.
