On the Teleological Judgment and the End of Nature
Quaeritur
Utrum iudicium teleologicum, quo mens naturam tamquam ad fines suos ordinatam interpretatur, sit mera reflectio regulativa humanæ rationis, an potius signum objectivum intelligibilis ordinis in ipsa natura, ita ut in eo praenuntiata sit ratio divina, quæ creaturam ad suam perfectionem dirigit.
Whether the teleological judgment, by which the mind interprets nature as ordered toward ends, is merely a regulative reflection of human reason, or rather an objective sign of an intelligible order within nature itself, such that in it is prefigured the divine reason which directs creation toward its perfection.
Thesis
The teleological judgment (teleologisches Urteil) in Kant’s Critique of Judgment expresses reason’s demand to view organized beings and the totality of nature “as if” they were purposively ordered. Though for Kant this demand is regulative, not constitutive, it nonetheless reveals a deep structure of intelligibility in which efficient and final causality converge. Theology may recognize in this reflective unity the vestige of divine wisdom—the Logos—wherein all things receive both their form and their end. The purposiveness discerned by reason is thus the temporal shadow of eternal intentionality.
Locus classicus
Kritik der Urteilskraft, §65 (AA V: 370–371):
“Ein organisirtes Product der Natur ist das, in welchem alles sowohl Zweck als Mittel ist. … Ein solches Product der Natur, wenn es einmal als Naturzweck betrachtet wird, giebt uns zuerst eine Idee von der Natur als einem System nach der Regel der Zwecke.”
“An organized product of nature is one in which everything is at once end and means. … Such a product of nature, once considered as a natural end, gives us for the first time an idea of nature as a system according to the rule of purposes.”
and §67 (AA V: 377):
“Die teleologische Beurtheilung der Natur nach der Analogie mit der Causalität durch Zwecke ist also nur ein Princip der reflectirenden Urtheilskraft, zum Behuf der Vernunft, die Erfahrung nach einem allgemeinen Gesetze zu systematisiren.”
“The teleological judging of nature by analogy with the causality through ends is therefore only a principle of the reflecting power of judgment, for the sake of reason, to systematize experience according to a universal law.”
Explicatio
In the Critique of Judgment, the teleological judgment follows the aesthetic as a higher mode of reflective reasoning. Whereas the judgment of taste feels purposiveness without a concept, the teleological judgment thinks purposiveness in the organization of nature. It is the intellect’s recognition that mechanical explanation alone cannot exhaust the phenomena of life.
Kant argues that certain natural entities, e.g., plants, animals, ecosystems, exhibit a reciprocal structure, for each part exists for the sake of the whole, and the whole sustains the parts. Such entities are Naturzwecke (natural ends). Though he forbids positing real teleology within nature, Kant insists that our reason must judge as if teleology were present, for otherwise the coherence of experience collapses. The teleological judgment thus functions as a transcendental condition of intelligibility, an indispensable heuristic by which nature appears as system rather than chaos.
Philosophically, this means that reason is not satisfied with mechanism. It yearns for meaning, for finality beyond blind efficient causes. The mind’s very structure inclines it to interpret nature as purposive, because the intellect itself, by seeking completion in understanding, is teleological. Kant therefore interprets teleological reflection as the expression of reason’s moral vocation within nature: the world must be seen as suitable to the realization of moral ends.
Theologically, this “as if” points beyond itself, for the necessity of viewing nature as purposive implies an ontological depth in which purposiveness is not mere projection but participation. The ordered interrelation of beings, the mutuality of part and whole, mirrors the rational and creative intentionality of the Logos. The teleologisches Urteil is the creaturely echo of divine wisdom organizing the cosmos ad gloriam Dei. In discerning purposes, reason encounters the world as symbolic of its Creator, the vestigium Providentiae.
The teleological judgment therefore bridges the aesthetic delight in beauty and the moral demand of freedom. It reveals that nature’s form is already ordered toward good, that contingency itself is enfolded in intelligible purpose. The unity Kant leaves indeterminate, theology identifies with the Logos, with the living reason by whom all things are made and toward whom they move.
Objectiones
Ob. I. The critical purist reminds us that Kant himself insists that teleology in nature is merely regulativ and cannot be regarded as constitutiv. To ascribe objective purposiveness is to transgress the limits of possible experience and reintroduce dogmatic metaphysics.
Ob. II. The mechanistic naturalist opines that modern science explains biological organization by physical law, evolution, and chance variation. Teleology is an anthropomorphic metaphor, and thus is not a real feature of nature. The world needs no purpose to be intelligible.
Ob. III. Materialist reductionism supposes that ends are illusions arising from human projection. Since nature’s apparent order is the byproduct of efficient causes and selection, any appeal to purpose is explanatory redundancy.
Ob. IV. Dialectical theology argues that finding divine purposiveness in nature blurs the radical discontinuity between revelation and creation. Providence is not readable from the world but declared in Christ alone. Natural teleology threatens the primacy of grace.
Responsiones
Ad I. Kant’s restriction is methodological, not ontological. To say that teleology is regulative is to confess that reason cannot demonstrate it, not that it is false. The regulative necessity of purposive thinking implies that intelligibility itself is purposive. Theology interprets this necessity not as proof but as participation, for the finite intellect it attuned to divine wisdom.
Ad II. Mechanism describes how, not why. Laws of physics account for regularity but not for the meaningful order those laws presuppose. The intelligibility of evolution itself depends upon an order of possibility that exceeds mere chance. Teleology need not contradict science. Rather it names the deeper rationality that science presupposes.
Ad III. If ends were mere projections, reason would deceive itself at its very core. Yet the human intellect’s drive to seek ends is inherent, not arbitrary. This drive reflects the structure of being itself as intelligible and goal-directed. The presence of purposiveness in thought signifies a correspondence with real finality in creation.
Ad IV. True, revelation consummates what nature intimates. Yet the Logos through whom all things are created is also the Word made flesh. The teleological order of nature is not a rival to grace but its foundation; it is the praeparatio evangelica of the world. Nature’s purposiveness is the created form of divine intentionality that revelation fulfills in Christ.
Nota
The teleological judgment occupies the middle ground between beauty and morality, between the grace of form and the demand of freedom. In the aesthetic, purposiveness is felt; in the teleological, it is conceived; in the moral, it is willed. Kant thereby restores final causality to philosophical dignity, albeit under the sign of reflection.
For theology, this marks the point where philosophy unknowingly touches creation’s inner logic. The world’s intelligibility is not accidental but the signature of divine intention. Every natural end is a finite parable of the ultimate end, a participation in the divine life. The teleological judgment thus prepares the intellect to recognize creation not as mechanism but as ordo amoris, an ordered love reflecting the eternal reason of the Logos.
Determinatio
The teleological judgment expresses reason’s necessity to interpret nature as a system of ends.
Though regulative for Kant, this necessity implies real participation of created reason in divine reason.
In nature’s teleology there appears the trace of Providence, the Logos himself, wherein efficient and final cause coincide.
Teleology is the middle path between aesthetic and moral cognition, preparing the intellect to recognize the unity of nature and freedom in the supersensible foundation.
Transitus ad Disputationem XXXIX: De Iudicio Reflectente
If teleological judgment teaches reason to think unity within nature’s manifold purposes, the next step is to inquire into the very power that makes such unification possible. The mind not only discerns purposes but gathers them into an intelligible whole. This reflectierende Urteilskraft—the reflecting power of judgment—mediates between the understanding that legislates laws and the reason that seeks their unity.
Therefore we proceed to Disputationem XXXIX: De Iudicio Reflectente, wherein it shall be asked how the reflecting judgment serves as the image and echo of the divine intellect, gathering the manifold of experience into a unity that anticipates the Logos Himself, in whom all relations of form and finality find their consummation.
