Book summary “An essay on man”: summary

Introduction

You face a unique crisis when you attempt to understand your own nature. Traditional definitions no longer hold because specialized sciences study you in disconnected fragments without a unified center. You possess no single physical substance or pure rationality to explain your existence.

Ernst Cassirer argues in An Essay on Man that your true definition is found in culture rather than biology. You are not merely an animal rationale, but an animal symbolicum, a creature who lives within a web of symbolic thought. This capacity creates art, language, myth, religion, history, and science.

The book explores how you transform raw biological stimuli into symbolic universes. You will discover how symbolic forms operate across human culture and history.

• How do you break free from the closed circle of animal reactions?
• What distinguishes mythical space and time from scientific ones?
• How does language move from emotional expression to abstract thought?

1. The Crisis of Human Self-Knowledge

Self-knowledge has always been the highest aim of philosophical inquiry. Yet it faces persistent methodological doubts and shifts between introspection and objective behaviorism.

Self-knowledge faces methodological anarchy because specialized sciences study man in isolation without a unified center.

Sceptics used introspection as a humanist tool to turn man back upon his own being. Modern psychology views pure introspection as precarious and inadequate. Radical behaviorism fails to capture the full picture because consciousness cannot be completely eliminated. You are left with a fragmented torso when relying on a single method.

The Socratic Approach

Socrates shifted the focus of philosophy from physical cosmology to the anthropological question of human nature. He used dialogical inquiry to abandon independent theories of nature and metaphysics.

Socrates walks outside Athens with Phaedrus, praises the landscape, but explains he loves knowledge and the men in the city are his teachers rather than the trees or country.

Stoic philosophy teaches that man's true essence depends exclusively on his inner judgment. Marcus Aurelius argued that external goods are indifferent and you must look to your ruling Reason.

Never fail to ask thyself this question and to cross-examine thyself thus: What relation have I to this part of me which they call the ruling Reason?

Modern Intellectual Anarchy

Christian anthropology reverses classical philosophy. Augustine asserted in the fourth century that human reason is obscured and corrupted by the Fall, making divine grace necessary. Pascal argued that human nature defies mathematical analysis because man is a mixture of being and nonbeing. After writing a treatise on conic sections at sixteen years old, Pascal distinguished geometry from the subtle spirit required to study human beings.

The sixteenth-century heliocentric system shattered the traditional hierarchy where you occupied the center of the universe. Evolutionary theory later destroyed arbitrary boundaries between species through natural selection.

Modern anthropological philosophy suffers from a crisis because specialized sciences approach you from isolated viewpoints. Thinkers like Nietzsche, Freud, and Marx impose preconceived patterns like the will to power or instincts. You find that the growing multiplicity of sciences fits human nature into a Procrustean bed and obscures the true concept of man.

2. From Animal Reactions to Human Responses

Biologist Johannes von Uexküll proves that every organism lives in its own subjective reality determined by anatomical structure. Receptor systems receive stimuli and effector systems react to them in a closed functional circle.

Animals live in a closed functional circle of signals, whereas human beings interpose a symbolic system between stimuli and responses.

Human responses are delayed by thought and symbolic activity. Language, myth, art, and religion form a symbolic net that prevents you from confronting physical reality directly.

Signals Versus Symbols

Signals and symbols belong to entirely different universes of discourse. Signals act as physical operators with a fixed relation to individual things. Symbols possess functional value and extreme versatility.

In Pavlov's experiments, dogs were trained to react to a bell as a signal for dinner, and a major's dog learned to wait for the rattling of a desk drawer before going for a walk.

Higher animals possess practical intelligence and imagination. Wolfgang Koehler and Robert Yerkes demonstrated that chimpanzees can use token rewards, choose larger boxes, or select objects of a common color, but these abilities remain rudimentary and prone to errors.

The Discovery of Naming

The fundamental boundary between the human and animal worlds lies in the difference between emotional language and propositional language. Wolfgang Koehler observed that chimpanzees express emotions through gestures and sounds, but psycholinguistic and psychobiological studies prove their phonetic gamut is strictly subjective and never describes objects.

Helen Keller, at 7 years of age, suddenly realized at a water pump that the manual spelling w-a-t-e-r applied to the gushing liquid, adding 30 new words to her vocabulary in a few hours.

Both Helen Keller and Laura Bridgman successfully constructed complex symbolic worlds and achieved mental development despite lacking sight, hearing, and speech.

Herder argued that speech is a general function of the human mind called reflection. Herder's philosophical conception finds empirical confirmation in brain injury research, where aphasia patients who lose symbolic speech also lose the capacity to think in general concepts and become confined to concrete immediate facts.

3. Space, Time, and Hypothetical Thought

Lower organisms and animals navigate space through bodily impulses and sensory orientation without any mental picture or idea of abstract space. A young chicken breaks from its shell and immediately picks up grains in its path through innate spatial orientation without ideational processes. Human culture introduces symbolic and abstract space, which abstracts away all disparate sensory varieties to create a universal framework for a cosmic order.

Human symbolic capacity transforms organic space and time into abstract systems and separates actual facts from unreal possibilities.

Symbolic Space and Time

The conceptual framework of scientific astronomy originated in Babylonian culture through the discovery and use of symbolic algebra. Babylonian astronomy utilized celestial phenomena to organize human existence, though it was still wrapped in mythical and astrological interpretations of divine and demonic powers.

Human memory is not a mere reproduction of past impressions, but a creative and constructive process of symbolic re-collection. Goethe titled his autobiography Poetry and Truth to describe how he used poetical and symbolic shape to find the truth about his life.

The human consciousness of time is inherently oriented toward the future, transforming mere expectation into an ethical and prophetic imperative. Isaiah, Jeremiah, and Ezekiel used prophecy not merely to foretell events, but to present the hope and assurance of a new heaven and a new earth.

Facts and Ideals

Unlike lower organisms confined to actual physical stimuli or a divine mind where all conceived things are real, human discursive intelligence depends on symbols. Laura Bridgman experienced difficulties in her early education when trying to comprehend supposititious cases or word problems in arithmetic as mere possibilities rather than actual events.

Scientific progress relies fundamentally on hypothetical or unreal conceptions rather than the mere accumulation of raw observational facts. Galileo founded his dynamics on the conception of an entirely isolated body moving without external forces, a condition that has never been observed and is never realized in nature.

Mathematical progress repeatedly introduces paradoxical and seemingly impossible numbers that are understood only when mathematics is recognized as a theory of symbols. Negative numbers introduced in the sixteenth century were referred to as fictitious numbers by Michael Stifel in his Arithmetica integra.

Ethical and political philosophy utilizes utopian and impossible constructs to break the inertia of the present and reshape the human universe. Thomas More designed his Utopia as a nowhere that exists at no point in space or time, yet proved its strength in the development of modern political thought.

4. The Functional Definition of Culture

Critique of Naturalism

Plato argued that human nature must be studied through the state because the individual soul is too complex and illegible, like a text written in tiny characters. Auguste Comte later shifted the study of man from individual psychology to sociological and historical thought. He asserted that humanity explains man rather than man explaining humanity.

Reducing human intelligence and culture to a fixed list of primary instincts is a methodological fallacy that substitutes a new name for an actual explanation. Thinkers like Taine attempted to reduce intelligence to animal associative mechanisms, while other empirical writers cataloged fifty and sixty instincts. According to John Dewey, treating these classifications as fixed entities in nature obstructs your understanding of life.

The Structural Approach

Man's essence cannot be defined by a metaphysical or physical substance or an inborn faculty, but must be understood functionally through his works.

Modern philosophy and science must abandon the old metaphysics of substance in favor of explanations rooted entirely in functions and relations. You discover that the circle of humanity is defined by a system of human activities held together by a vinculum functionale rather than a substantial bond.

Before conducting historical research into human culture, you must apply descriptive structural analysis to classify and organize the endless flow of facts. Heinrich Wölfflin established fundamental structural categories like classic and baroque to analyze the history of art without getting lost in endless details. A philosophical description of civilization requires universal categories of this type.

Although cultural activities such as myth, art, religion, and science often conflict materially, they share a formal unity through a common creative process and function. Philosophy seeks a universal synthetic view that reveals all diverse creations of culture as variations on a common theme, making that underlying theme audible and understandable as a pium desiderium.

5. Myth and Religion

Myth and religion resist purely logical analysis and cannot be reduced to simple rational errors. Rationalist theories attempt to explain myth through intellectual reduction, such as solar, meteorological, or Freudian sexual interpretations. These theories fail because the myth-making function is fundamentally non-theoretical and defies scientific categories of empirical truth.

Mythical perception experiences the world through emotional and physiognomic qualities, evolving into ethical monotheism and moral obligation.

Malinowski notes that departmental mythologists fight fiercely for their favored heavenly body, while Freud reduces all myths to variations of sexuality. Unlike empirical thought, which abstracts constant features into physical objects, mythical perception views the world as a dramatic network of conflicting, emotional forces that are friendly or uncanny, benignant or malignant.

Primitive Unity of Life

Primitive thought is governed by a deep conviction of the fundamental solidarity and unbroken unity of all life forms, overriding empirical distinctions. Nature is viewed as one great society where humans hold no privileged rank.

Karl von den Steinen relates that members of certain Brazilian Indian clans asserted they were one with aquatic animals or red parrots. Frazer notes that among the Dieri tribe in Australia, a seed-totem chief was spoken of as being the plant itself.

Myth and primitive religion operate as an obstinate negation of death, treating mortality as accidental rather than natural. Spencer and Gillen point out that among aboriginal Australian tribes of the central deserts, no such thing as natural death is recognized. Breasted notes that Pyramid Texts record humanity's passionate revolt against death with the indomitable assurance that the dead live.

From Magic to Ethics

Magic is not merely a pseudo-science, but an early expression of human self-confidence and spiritual energy in dangerous pursuits. It emerges under strong emotional strain during uncertain endeavors and trains people to believe in their own spiritual energy.

Malinowski reports that among the natives of the Trobriand Islands in Melanesia, highly developed magic only occurs when a pursuit is dangerous and its issues are uncertain, whereas minor economic tasks require no magic.

The evolution of higher monotheistic religions replaced magical indifference with a purely ethical focus centered on law and righteousness. M.N. Dhalla outlines how Zoroastrianism demands that individuals make a conscious choice between truth and falsehood, becoming active allies of the wise lord Ahura Mazda. Higher religions successfully transformed primitive taboo systems from mechanical physical restrictions into internal moral obligations requiring purity of the heart.

6. Language

Language evolves from the magical word to semantic structures and phonological systems that enable conceptual classification and objectification.

Max Müller viewed myth as a disease of language born from metaphors. A more accurate view is that primitive man transferred his early social experiences with parents to nature. He treated the world as a society influenced by magic words. Max Müller cited ancient religious traditions where the supreme God commits crimes due to the inevitable metaphors required by ancient language.

When primitive man discovered that nature was inexorable, confidence in magic collapsed. This crisis led to a shift where the word became the principle of the universe in early Greek philosophy with Heraclitus. Assuming that knowledge requires an identity between the knowing subject and the object known, ancient thinkers tried to bridge the gap through sound imitation. Plato critiqued this in Cratylus, yet etymology remained central until modern scientific methods were established in the nineteenth century. Plato's dialogue Cratylus presents Socrates examining the onomatopoeic thesis.

The Greek Sophists treated language primarily as an instrument for social action through rhetoric rather than a description of reality. Maintaining that man is the measure of all things, they argued that names arouse human emotions rather than describe objective nature. Biological theories traced human speech back to emotional interjections and animal cries. Darwin demonstrated in The Expression of the Emotions in Man and Animals that expressive sounds are dictated by biological rules.

The Meaning of Meaning

Wilhelm von Humboldt shifted the philosophy of language by viewing language as an ongoing mental energy and world-perspective. Humboldt utilized the extensive materials on aboriginal American languages brought back by his brother Alexander von Humboldt between 1836 and 1839. He argued that language is an energeia rather than an ergon, creating distinct world-perspectives.

Structuralism and Linguistic Form

Modern structuralism treats language as an integrated system where descriptive analysis and phonology supersede historical explanations. Ferdinand de Saussure separated synchronical linguistics from diachronical history. Trubetzkoy and the Prague linguistic circle established phonology, defining phonemes as minimum units of distinctive meaning. R. K. Rask and Jakob Grimm established regular formal sound correspondences in Germanic languages in 1818. Panini's Sanskrit grammar was produced between 350 and 250 B.C.

The child's hunger for names marks a psychological turning point toward objectification. Helen Keller and Laura Bridgman showed an immense eagerness to learn names once they grasped symbolism. D. R. Major observed a child in the twenty-third month developing a mania for naming objects.

Classification in human speech is guided by human interests rather than a single logical scheme. Hammer-Purgstall noted five to six thousand terms for the camel in Arabic without a general biological concept. Karl von den Steinen found that the Bakairi tribe has individual names for every species of parrot and palm, but no word for the genus.

7. Art

Art operates as an autonomous continuous process of concretion and discovery of pure forms rather than a passive imitation of nature.

The Autonomy of Art

Before 1750, aesthetics attempted to reduce art to an alien jurisdiction. Alexander Baumgarten published his Aesthetica to construct a logic of the imagination. Kant established the autonomy of art in his Critique of Judgment. He proved it operates independently of theoretical knowledge and moral laws.

The traditional mimetic theory viewed language and art primarily as imitations. Aristotle viewed delight in representations as a theoretical learning experience. You observe realistic depictions of painful things and gather meaning. Aristotle noted that we delight in viewing realistic artistic representations of painful things, such as dead bodies or low animals, because we are simultaneously learning and gathering meaning.

Art as Discovery and Freedom

Rousseau and Goethe shifted aesthetic theory from imitation to characteristic art. Goethe wrote his paper Von deutscher Baukunst in 1773 during his Sturm und Drang period. Art is not a passive imitation or abbreviation of reality like science. It provides an intensification of reality through pure sensuous shapes.

Ludwig Richter recounted how he and three friends painted the same landscape in Tivoli with the strict intention of reproducing nature accurately, yet produced four entirely different pictures based on individual temperament.

Tragic and dramatic art achieve catharsis through transformation. Shakespeare's Hamlet explains that the purpose of playing is to hold a mirror up to nature, showing virtue and scorn their own forms without infecting the audience with actual destructive passions like Macbeth's ambition.

8. History

Unlike physical things with a fixed nature, human life must be understood through history. Modern thought rejects classical Eleaticism and recognizes that your being is constituted by historical consciousness rather than a static substance.

History reconstructs past human culture through symbolic documents and serves as an instrument of objective anthropomorphism and self-knowledge.

History and Scientific Thought

History and science share an inner logical homogeneity and obey the same general laws of reasoning. The historian uses the same inductive inferences as the physicist, but focuses on a former stage of human culture.

In 1755, Kant developed an astronomical theory and a universal history of the material world. Yet historical facts are not immediately observable like physical data. They must be reconstructed through the critical philological testing of symbolic documents and monuments.

An old Egyptian papyrus found under the debris of a house initially appeared to be a notary's mundane notes. After the discovery of four hitherto unknown comedies of Menander beneath the first text, it transformed into a valuable historical document of Greek culture.

Objective Anthropomorphism

Attempts to reduce history to a rigid science governed by statistical laws fail because they treat living human action like puppet motions. In 1857, Buckle published his History of Civilization in England, while Lamprecht later wrote a German History spanning twelve volumes. These works relied on moral statistics and historical fatalism, yet statistics only describe collective phenomena rather than unique symbolic acts.

Great historians act as retrospective prophets, or rückwärts gekehrter Prophet, who resurrect the past driven by present human needs. History lives and breathes entirely in the human world. It achieves an objective anthropomorphism that frees you from the prejudices of a single moment and enriches your ego.

9. Science and Cultural Unity

Science as Symbolic System

Science represents the highest attainment of human culture, moving from qualitative classifications to a universal mathematical symbolism of relations. Pythagorean philosophy marked the natal hour of this conception by introducing numbers as a universal element revealing cosmic order.

Pythagoras discovered the dependence of the pitch of sound on the length of vibrating chords, showing that beauty and cosmic order are reducible to simple numerical ratios.

Disciplines like chemistry and biology must pass through prescientific, qualitative stages before achieving a quantitative, deductively formulated theory. Alchemists possessed an astounding talent for observation and amassed valuable facts, but presented them in a half-mythical language full of obscure and ill-defined terms. Scientific determinism is not a metaphysical decree or a mechanical formula, but a methodological regulative idea for interpreting nature.

Science achieves universal mathematical symbolism, while culture maintains a dynamic functional unity through opposing creative forces.

The Dynamic Equilibrium of Culture

The unity of human culture is not an ontological homogeneity, but a dynamic functional unity born of contrasting and opposing forces. Heraclitus compared this to the bow and the lyre, illustrating harmony in contrariety where things torn in different directions come into accord. Every cultural domain experiences a fundamental polarity and ceaseless struggle between stabilization and evolution, tradition and innovation.

In primitive religion, words of a magic formula or phases of a sacrifice must be repeated in an invariable order because any change would annihilate their force.

Diverse domains of human culture such as psychology, myth, religion, language, art, science, and history are ultimately different roads leading to a common center. Humanity cannot be defined merely by a rational essence, but must be understood as an animal symbolicum due to its capacity for world-building through symbolization.

Conclusion

Human nature is defined not by rationality or physical substance, but by the capacity for symbolic thought across culture, myth, language, art, history, and science.

You can now see how all diverse cultural forms integrate into a coherent symbolic universe. Myth, language, art, history, and science are not isolated human activities. They represent interdependent expressions of one single symbolic energy. Each form contributes a unique dimension to the construction of human reality. You do not discover human nature by looking inward for a static essence. You realize human culture by participating actively in this vast symbolic network.

1. Recognize that your direct experience is always mediated by symbols rather than raw stimuli.
2. Cultivate your language skills to move from emotional reactions to conceptual clarity.
3. Engage with myth and religion to understand the persistent emotional depths of human solidarity.
4. Explore art as an autonomous form of perception that reveals dynamic structural realities.
5. Study history to transform the dead past into a living instrument of self-knowledge.
6. Master scientific symbolism to achieve universal truth without losing sight of cultural unity.
