Contemporary philosophers of biology describe organisms as dynamic, self-developing organizations, while biologists have identified many of the molecular and environmental conditions that regulate organic development. Yet such accounts often leave morphological change itself underdetermined: how forms arise from one another within ordered developmental processes. Johann Wolfgang von Goethe developed a method aimed at apprehending such formative processes themselves. He sought a dynamic law that could be constructively imagined-allowing consistent possible plants to be generated from it-and rediscovered in the formation and transformation of real plants. The present study applies this Goethean conception to leaf metamorphosis in flowering plants (heteroblasty). It develops a generative model of leaf shape comprising four formative tendencies-Stemming, Spreading, Differentiating, and Pointing-integrated into the polar components Size (S) and Form (F), and applies this model both to the metamorphic series of leaves along the shoot and to the ontogeny of individual leaves. Landmark measurements of seven adult leaf series from five families, together with ontogenetic series of Lepidium sativum and Lapsana communis, reveal an inverse relationship: adult leaf series proceed S → F, whereas individual-leaf ontogeny proceeds F → S. Both developmental processes can be jointly represented by a common logarithmic ideal rule (W-curve field). The same formalism can generate consistent metamorphic leaf series beyond the measured species. It thereby renders organic forms comprehensible as momentary manifestations of directed formative processes, while making their transformations constructible and empirically testable.

Rudolf Steiner’s Grundlinien einer Erkenntnistheorie der Goetheschen Weltanschauung (Outline of an Epistemology of Goethe's Worldview, 1886) seeks to articulate the epistemological foundations of Goethe’s scientific method. Here I reconstruct the book with a particular focus on the cognition of organisms and read it in systematic relation to Kant, whose analysis of teleological judgment provides the clearest foil for Steiner’s project. The guiding question is under what epistemic conditions living beings can become objects of genuine knowledge rather than merely regulative judgment. I reconstruct the argument in five steps: (1) pure experience as a structureless manifold; (2) thinking as a self-transparent and law-governed activity within experience; (3) cognition as the reunification of perception and concept under empirical constraint; (4) the contrast between inorganic and organic cognition; and (5) the claim that organisms can be understood through Goethe’s concept of Typus, a developing method, and an intuitive power of judgment (anschauende Urteilskraft). Steiner’s reconstruction of Goethe thus yields a position that transforms Kant’s view of teleological judgment as merely regulative. A concluding section considers the relevance of this argument for current debates on organism-centred theoretical biology and the relation between subject and object in biological cognition. I suggest that Goethe’s method as interpreted by Steiner deserves renewed attention as a systematic attempt to articulate the epistemological conditions of a participatory science of the organic.

The question of biological form occupies only a marginal place in mainstream biology, where the neo-Darwinian framework treats form as historically contingent and selectively preserved. Such explanations account for how a form arose and what it does, but not for what it is. This paper presents a method to cognize organic form as form. It reconstructs Goethe’s four-stage method of morphological inquiry—observation, comparison, recognition of formative law, and productive intuition—and carries it from his study of the developing plant, whose forms transform over time, to the adult human skeleton, where the parts are given together and the movement lies in comparative imagination. The Goethean account describes a Gestalt integrating the polarity between the compact, enclosing, resting head and the radially differentiated, supporting, mobile limbs through the mediating, rhythmic structure of the trunk. This organization recurs in varied configurations within individual regions. Productive intuition apprehends the idea of this Gestalt by grasping how particular forms become intelligible through their relations to the whole. The paper thus shows how disciplined comparison and productive intuition can make the idea of an organic form accessible through the relations among its parts.

This paper argues that Edward Stuart Russell’s 1930 analysis of biological abstraction maps contemporary organism-centered biophilosophy and identifies the cognitive procedure required for a full understanding of the self-forming, purposive, agential, and environmentally embedded organism. Russell distinguishes two structurally distinct modes of abstraction — from the organism as a whole, and into isolated parts — coupled into a chain running from first-person experience to the organism as a mere statistical aggregate. Read forward, the chain articulates the necessity of scientific cognition and its characteristic misuse, the fallacy of reduplication: reinserting into an isolated component the organizational power that analysis had removed from the whole. Read backward, it specifies five requirements: recovery of formal organization, temporal constitution, teleology, agency, and first-person Umwelt-relation. The major currents of contemporary organicist thought — organizational closure, process ontology, teleological realism, the agency debate, and phenomenological enactivism — address these requirements and secure the principle under which organisms are cognized, yet each presupposes what it seeks to explain: the determinate formative content of a particular organism. The Goethean morphological tradition, whose epistemology Rudolf Steiner reconstructed, supplies at each level an intuitive procedure reaching this formative content, building on constructive intuition of the organism’s own formative principle.

The living organism poses a persistent challenge for scientific explanation. While modern science successfully explains inanimate phenomena—often through mechanical causes, general laws, and mathematical construction—Kant argued that organisms resist these modes of explanation. This paper reconsiders this epistemic limit by examining Johann Wolfgang von Goethe’s morphological investigations and Rudolf Steiner’s philosophical interpretation of them. I argue that Goethe’s morphology and Steiner’s epistemology reveal a fourth mode of scientific explanation—productive-intuitive explanation—in which the formative activity of living organisms becomes intelligible through the productive activity of cognition itself. Goethe reconstructs the generative law of plant development in inner intuition—akin to mathematical construction—allowing the morphologist to reenact in thought the formative process and thereby gain insight into the objective possibility of organic form. Steiner further clarifies this approach by arguing that the formative activity of the organism can itself become accessible within the productive activity of thinking. On this basis, the paper develops a four-level typology of scientific explanation—causal-mechanical, deductive-nomological, constructive-mathematical, and productive-intuitive—in which the cognition of living beings culminates in a form of explanation grounded in the coincidence of knower and known. What appears in Kant’s philosophy as an epistemic limit thus becomes the starting point for a deeper account of scientific intelligibility in the study of life.

The living organism raises a distinctive epistemological problem: biology presupposes wholeness, purposiveness, and self-generation, yet these cannot be derived from interactions among independently identifiable parts. I argue that the classic opposition between mechanism, vitalism, and organicism reflects different responses to this difficulty—how organisms become intelligible objects of knowledge. Building on Kant’s analysis of teleological judgment, I offer a systematic epistemological reading of Goethe’s morphology and Steiner’s interpretation of it. Goethe’s conception of plant metamorphosis is presented as a morphological construction: not the subsumption of data under fixed concepts, but the use of transformable ‘living concepts’ that reconstruct a formative process, analogous to (yet distinct from) mathematical construction in physics. Steiner further developed this idea by claiming that productive reconstruction can disclose not only lawful organisation but the organism’s self-generating activity, that is its formative force. In dialogue with Fichte’s notion of intellectual intuition, I propose that reenacting organic formation in thought establishes a structural correspondence (not identity) between productive cognitive activity and organic self-formation. The result is neither ontological nor methodological vitalism, but an epistemology of organicism which complements, rather than replaces, causal-mechanistic analysis.

Organisms represent a persistent challenge for science and philosophy. Reductionist approaches increasingly appear insufficient, while organicist accounts describe the essential features of living beings without explaining their possibility. Immanuel Kant showed that organisms must be conceived as teleologically structured and self-forming wholes in order to be recognized at all. Yet his critical philosophy also reveals the limits of such recognition: while the understanding cannot perceive organicity as an objective feature of nature, reflective judgment can attribute purposiveness only in a merely regulative way. In this paper, I examine in detail the epistemological conditions for recognizing a developing organism and argue that the cognition of organic structure, development, purposiveness, and agency requires the coordinated operation of sensory apprehension, imaginative reproduction, conceptual recognition, and spontaneous apperception. Each of these faculties entails a distinct relation between subject and object. I show that in the cognition of development, purposiveness, and agency, the Kantian separation between understanding and reason becomes strained, for the subject–object division presupposed in the application of the categories progressively diminishes. I propose that this tension indicates a limit of Kant’s framework and motivates a systematic extension of it: the “causality of the concept,” which for Kant remains merely regulative, becomes a constitutive condition for the possibility of experiencing an organism as a self-organizing and agential whole. Such an expanded epistemological analysis suggests corresponding ontological implications and enables a deeper understanding of the reality of living beings.

This paper examines the philosophical foundations of Goethe’s morphological studies, in particular his concept of the ‘archetypal plant', which can be described as the dynamic principle of a living surface that governs plant formation through alternating processes of expansion and contraction. The Austrian philosopher Rudolf Steiner claimed that Goethe’s approach offers a scientifically grounded approach to understanding organic form and development through what may be termed empirically based, productive intellectual intuition, namely the mental reconstruction of an organism’s formative principle and laws. Here it is shown that Goethe’s rational organicism, as elaborated by Steiner, provides a conceptual and methodological framework that suggests a solution to the long-standing problem of understanding organismic properties like autopoiesis, autonomy and agency. Yet, Goethe struggled to identify a comparable principle for animals. Steiner argued that animal life is determined by a psychological principle—a non-physical centre of sensation and movement that structures the organism in relation to its environment—and that this, too, can be grasped in productive intuition. The paper reconstructs the animal archetype by delineating its essential features: the relations between its interior and exterior, realized in sensory, nutritive and motor functions. The study concludes that Goethe’s rational organicism can serve as a methodological complement to the organicism of the current philosophy of biology.

This paper investigates the enduring philosophical challenge of how a living organism may be understood, through the epistemological perspectives of Immanuel Kant, Johann Wolfgang von Goethe, and Rudolf Steiner. Kant's analysis of the necessity of judging organisms as purposive and self-generating wholes is presented as foundational to any systematic account, insofar as it addresses the very conditions under which an organism can become an object of cognition. However, due to Kant's strict separation of sensory intuition from conceptual understanding, he regarded purposive self-generation as merely heuristic, lacking causal legitimacy within empirical nature. In contrast, Goethe's participatory and intuitive method, articulated in The Metamorphosis of Plants, integrates empirical observation with imaginative reproduction to achieve an intuitive grasp of an organism's life and transformation. Conceived as a dynamic bridge between perception and concept, Goethe's approach was subsequently interpreted and philosophically developed by Steiner. Steiner argued that an organism's essential nature can be apprehended through a productive, intuitive mode of cognition that mentally reconstructs the organism's formative principles and self-generative force. His position, which bears affinities to Fichte's notion of intellectual intuition, both elucidates and extends Goethe's method by asserting that the organism's formative force is accessible through active, intuitive cognition. Thus, Steiner demonstrated how Goethe's approach transcends Kant's limitation on the knowability of organic life, enabling the empirical observation of spiritual efficacy in material nature. This paper ultimately contends that the Goethe-Steiner method offers an empirical yet intuitive framework and method for understanding the life and formation of living organisms.

In der Auffassung Rudolf Steiners bedeutet Intuition nicht einen spontanen Einfall mit unklarem Ursprung, sondern eine Einsicht von höchster Klarheit und Sicherheit. Im intuitiven Erkennen wird die Kluft zwischen dem Erkennenden und dem Erkannten überwunden. Durch ihre Tiefe ist die Intuition der mittelalterlichen unio mystica vergleichbar, durch ihre vollkommene Transparenz aber auch der exakten mathematischen Erkenntnis. Rudolf Steiner entwickelte sein Verständnis der Intuition in Bezug auf Goethes ‚anschauende Urteilskraft‘ und die ‚intellektuelle Anschauung‘ des deutschen Idealismus. Intuition macht deutlich, was Steiner unter Geist und Geisteswissenschaft verstand. Hier wurden alle Darstellungen zur Intuition aus neunzehn Schriften und etlichen Aufsätzen Rudolf Steiners zusammengestellt und erläuternd kommentiert. Von den Einleitungen zu Goethes naturwissenschaftlichen Schriften über Die Philosophie der Freiheit und Die Geheimwissenschaft im Umriss bis zu Steiners letzten Schriften wird ein umfassender Überblick über dieses zentrale anthroposophische Thema gegeben, der einen Einblick in die Grundlage der Anthroposophie vermittelt. Die Zusammenstellung zeigt, wie Rudolf Steiner seine frühen philosophischen zu den späteren anthroposophischen Anschauungen weiterentwickelte.

This article outlines an epistemological perspective to understand the organism as a temporally changing whole. To analyze the mental faculties involved, the organism’s development and persisting existence is differentiated into four interdependent aspects: descent, future existence, persistent species, and environmentally adapted physical appearance. It is outlined that these aspects are recognized by comparative memory, concept-guided anticipation, conceptual thinking, and sensory perception, respectively. Furthermore, it is pointed out that these aspects correspond to the famous four Aristotelian “causes” or principles of explanation. The descent of an organism corresponds to Aristotle’s efficient principle (“where does it come from?”), its future existence to the final principle (“what is if for?”), its physical structure to the material principle (“out of what is it?”) and its persistent species to the formal principle (“what is it?”). Aristotle regarded the unity of the efficient, formal and final principle as the ontological cause of the organism and called it the “soul” (psyche), while the material principle can be understood to represent its “body” (soma). I suggest that Aristotle’s “soul” corresponds to three of the four mental faculties required for cognition of a self-maintaining organism. I argue that in a Kantian perspective, the Aristotelian “soul” represents the condition for recognizing an organism at all. Therefore, the Aristotelian principle of life becomes intelligible and even empirically observable through the inner sense. In summary, I suggest that the four aspects of the organism described here can be viewed as the general, epistemological and ontological principle of the organism, the Bio-Logos.

This article proposes an empirical approach to understanding the life of an organism that overcomes reductionist and dualist approaches. The approach is based on Immanuel Kant’s analysis of the cognitive conditions required for the recognition of an organism: the concept of teleology and the assumption of a formative power of self-generation. It is analyzed how these two criteria are applied in the cognition of a developing organism. Using the example of a developmental series of a plant leaf, an active and relational process between observer and developing organism is shown, within which the teleology and self-generating power of the organism can be empirically observed through the mental faculties of understanding and will. Furthermore, it is emphasized that, according to Kant, even physical objects are not readily given, but are actively constituted through the unification of sense perceptions with concepts. This Kantian mode of objectification facilitates cognition of the physical properties of an organism. It can be supplemented with a participatory and co-constitutive mode of realization, in which the life of the organism (its teleologically organizing and self-generating power) can become an object of empirical research. Furthermore, it is argued that the participatory mode also facilitates an expanded conception of nature that allows for the existence of living beings within it. Finally, an analogy to Goethe’s approach to the living organism is highlighted. In summary, it is stated that to understand life, one must consciously participate in it.

The question of the holistic structure of an organism is a recurring theme in the philosophy of biology and has been increasingly discussed again in recent years. Organisms have recently been described as complex systems that autonomously create, maintain and reproduce themselves while constantly interacting with their environment. Key focal points include their autopoiesis, autonomy, agency and teleological structure. This perspective marks a significant advancement from the 20th-century viewpoint, which predominantly saw organisms as genetically programmed, randomly generated and blindly selected survival-machines. However, crucial questions about the shape and development of organisms still lack answers. Shape and development are deeply interconnected and seem to require a holistic approach. Here, I will briefly outline a phenomenological perspective which could provide a framework for seeking answers to these fundamental questions. In particular, I propose a common four-fold phenomenal structure of the developing organism and the cognising consciousness, which makes it possible to observe the agential and teleological structure of the organism "from within". This fourfold structure also describes the molecular level and thus provides a general organismic concept. It furthermore corresponds to the four Aristotelian "causes" (conditions).

Warum verlief die Evolution bis zum Menschen und ist nicht auf einer früheren Stufe stehen geblie­ben? Verdanken wir unser Dasein einer über Millionen von Jahren abgelaufenen Kette von Zufällen? Kann man das Leben aus toter Materie erklären? Und was ist Leben überhaupt? Die Antworten, die die Naturwissenschaft auf diese grundlegenden Fragen gibt, können ein tieferes Nachdenken nicht befriedigen. In diesem Buch wird gezeigt, dass in der naturalistischen und darwi­nistischen Erklärung des Lebens und seiner Evolution ein entscheidender Faktor übersehen wird, nämlich der erkennende Mensch. Die Fragen nach dem Lebendigen und nach Richtung und Sinn der Evolution können beantwortet werden, wenn das erkennende Bewusstsein nicht als Zuschauer, sondern als integraler Bestandteil der Wirklich­keit mitberücksichtigt wird. In der Selbstanschauung des Erkennens können die Kräfte und Gesetze organischer Entwicklung beobachtet und erforscht werden. Es zeigt sich, dass die Evolution kein zufälliges Geschehen war, sondern der organische Gesamtprozess der Menschwerdung.

This book shows that in the naturalistic and Darwinian explanation of life and its evolution, a decisive factor is overlooked, namely the human, knowing mind. The questions about life and its evolution can be answered if consciousness is taken into account not as a spectator, but as an integral part of reality. In the first-person-perception of cognition, the forces and laws of organic development can be observed and explored. It becomes apparent that evolution was not a random event, but the organic overall process of the becoming of man.
