Every person knows what alive means. Every child recognises the difference between a beetle and a stone. And yet: biology, whose central subject is life, cannot define it. It describes functions — metabolism, reproduction, responsiveness — but it cannot answer the question of what makes the living living, because its method treats life as an object from the outset. Aliveness is not a biological property. It is an ontological foundation: the primary, the irreducible, from which everything else proceeds.
#Why the Dead Cannot Be Primary
Natural science proceeds the other way round. It explains the living from the non-living: chemistry produces biology, biology produces consciousness. This derivation tacitly presupposes that the dead is the default state and the living the exception. Jochen Kirchhoff contested this priority with a sharpness that calls the entire scientific worldview into question: life arises only from life (cf. Kirchhoff, KI und Transhumanismus, 51:30). No one has ever observed life emerging from the dead. It is a bare assertion, a bad ideology.
Schelling had formulated this reversal two centuries earlier. In Von der Weltseele, he describes how a vivifying force resists dead matter: nature does not abandon organic matter to the forces of attraction and inertia but opposes them with a principle of life (cf. Schelling, 1798). For Schelling, the mechanical is no primal ground but the result of a withdrawal: life pushed back, the negated organism. Already in the Ideen zu einer Philosophie der Natur, he warned against treating nature like a clockwork and then marvelling that it moves (cf. Schelling, 1797). Whoever seeks to derive the living from the dead has already missed the starting point, because they declare the derivative to be the origin. Goethe formulated the same insight from the side of experience: when living foundational experience is eliminated, one ends up juggling with technical abstractions in a space that has nothing to do with life.
#Three Marks That Cannot Be Fixed
If aliveness is the primary, it must show itself phenomenologically. In Die Erlösung der Natur, Kirchhoff unfolds three determinations of the living: indivisibility, the irreducible wholeness that is lost in any dissection; gestalt, self-being as form, not as formless mist; and selfhood (Ichheit), a substantial centre that cannot be vacated without destroying the being (cf. Kirchhoff, 2004).
Already Aristotle called this inner directedness entelechy: that which carries its purpose within itself (cf. Aristotle, De Anima). The living organism develops not because an external force drives it but because an inner form realises itself. A colossal complexity that can never be entirely fixed, because the very act of fixing is an intervention that turns the living into an object and thereby de-livens it. Front and back, right and left, above and below feel different in the living body. This asymmetry is no epiphenomenon — it is the signature of aliveness itself.
#Living Thoughts, Dead Thoughts
The distinction concerns not only organisms. There are living thoughts and dead thoughts. A dead thought is an abstract something circling in the mind without touching anything. A living thought is a thought that is embodied, from which something arises (cf. Kirchhoff, Interview 2026-02-12). This distinction comes from Schelling’s natural philosophy and reaches deeper than the familiar separation of theory and practice. It concerns the ontological quality of thinking itself.
If you think a thought that changes you, it was alive. If you repeat a thought that moves nothing, it was dead, however sharp its formulation. Novalis described this difference when he said that consciousness is a living operative force, not a subjective accompaniment of neural processes. Thoughts are effective factors of the cosmos (cf. Kirchhoff, Novalis: der Dichter als Philosoph, 69:55). This presupposes that the cosmos itself is a space of consciousness in which thinking acts upon reality.
#What the Machine Reveals
The confrontation with artificial intelligence has sharpened the question of aliveness. Everything that can be mechanised can be handed over to the machine. The machine calculates faster, sorts more precisely, processes more data. But precisely in doing so, it reveals what cannot be mechanised: the stubbornly living, the imperfect, the genuinely human (cf. Kirchhoff, Herrschaft der Algorithmen). The machine is an artefact, de-livened. It can replicate what the intellect can abstract from the processes of nature, but it cannot beget, cannot bring forth from its own kind. The fundamental difference: the mechanical is steered from outside to inside; the organic organises itself from inside to outside.
Intelligence, understood this way, is a capacity to recognise reality and truth and to establish connections within the living (cf. Kirchhoff, The Great Reset als Technische Welterlösung, 60:16). A robot cannot do this, because it lacks that from which knowledge arises in the first place: a living relationship to the world.
#The Living Cosmos as Prerequisite
The decisive step leads from the individual being to the whole. If we are alive, we must live in a living world, because what is alive arises only from what is alive (cf. Kirchhoff, Der Weltenwille als Baustoff und Lebenstrieb des Kosmos, 35:30). A dead cosmos — infinite, empty, hostile to consciousness — ruins the human being who must endure within it. The flight into substitute worlds, cyberspace, transhumanism, does not solve the fundamental problem, because these worlds are manufactured and dead.
Kirchhoff called this insight the only chance the human being has: to connect with the cosmically living (cf. Kirchhoff, Das Unendliche und das Endliche, 69:56). If that does not succeed, we remain neurotic spectres in a space that does not carry us. Natural philosophy is the attempt to recover this space by conceiving the cosmos as an ensouled whole in which spirit inheres. The cosmic anthropos describes the human being who recognises themselves in this aliveness, rather than grasping themselves as a biological accident in an indifferent universe. And the birth process shows how aliveness unfolds in crises and transitions: not as repair of a defect, but as passage into an expanded form.
Aliveness is thus neither property nor state, but the way in which reality brings itself forth. Whoever makes it into an object has already missed it. Whoever denies it nevertheless stands within it. The question is not whether the world is alive, but whether we are willing to expose ourselves to this aliveness rather than replacing it with abstraction.
