Relation to the world· Nature and the living
Finalism
Axis: Explaining nature — How should natural phenomena be explained: by mechanisms, by purposes, or by a vital impulse?
A natural phenomenon is fully understood only by grasping what it occurs for: the organ has a function, the organism tends toward its completed form. Nature is ordered by ends, not merely pushed by causes.

Aristotelianismexplicit
The starting point is the observation of living things: an acorn becomes an oak and not a beech, an organ develops for a function, signs that an end orients the process. To treat this regularity as a mere accident of matter, as Democritus' mechanism does, explains nothing; beyond matter one needs the , the that-for-the-sake-of-which a thing exists. Finalism is thus not projected onto nature but read within it, and it is the internal natures of beings, not an external craftsman, that carry them toward their end.

Stoicismexplicit
The Stoic cosmos is ordered by : fate is the rational chaining of all causes, directed toward the good of the whole. Causality is therefore fundamentally finalist, teleological, even as it unfolds as an unbreakable chain of causes that nothing interrupts.

Thomas Aquinasexplicit
Thomas inherits 's four and the primacy of the final cause: every agent acts for the sake of an end, and it is this orientation that makes nature intelligible. But he radicalizes finalism by referring it to God: the order of ends observable in the world, which culminates in the fifth way, presupposes an intelligence directing the beings devoid of knowledge toward their goal, as the arrow is directed by the archer. Nature is therefore not a blind mechanism but a willed order, in which each thing tends by its form toward the perfection that belongs to it.

Aristotleexplicit
Why does a thing come to be? Aristotle finds incomplete any answer that invokes only matter or the collision of bodies, as the Presocratic physicists did: four are needed (material, formal, efficient, final), and it is the final cause that orders them. His decisive argument comes from living things, where observation reveals organs made for a function: the acorn becomes an oak, the eye serves for seeing. He extends this oriented regularity to all of nature, which does nothing in vain: the end is no conscious plan but the immanent term toward which a process tends by its very form.

Leibnizexplicit
Since the monads are without windows, no substance really acts on another: the coordination of soul and body, like that of all substances among themselves, can come neither from direct influence nor from God's repeated assistance (occasionalism), but from a pre-established harmony set up at creation, like two clocks tuned in advance. Hence the rehabilitation of the set aside by mechanistic science: the realm of efficient causes (bodies) and that of final causes (souls, ends) coincide without mingling. Everything is explained mechanically in the detail of phenomena, yet the ultimate reason for their arrangement is final, inscribed in the divine choice of the best. Finalism thus takes metaphysical precedence without abolishing mechanism.

Plotinusinferable
is not a mechanical production but a derivation oriented toward the good: each begets the lower one because the perfect, by superabundance, cannot but radiate, and all that proceeds from it is drawn by the return toward its principle. Causality is therefore fundamentally final, suspended from the Good as its end, the opposite of a universe of blind collisions. Nature itself produces by contemplating, like a sleep of the soul that imitates the intelligible.

George Berkeleyinferable
For Berkeley sensible ideas are utterly inert: an idea can produce nothing, so no body is ever a true cause. The only real causality is that of a will, and we experience it solely in the activity of a mind. The regularity of nature is therefore not a mechanical chain of impacts but the constant order by which God, the one cause, produces our ideas in us: what we take for natural causes are merely the regular signs of effects to come. Nature thus receives a finalist reading, governed by the ends of an ordering mind, against the mechanism of , for whom matter acts by its motion alone.

Hegelinferable
Nature and spirit are not explained by mechanism alone: an immanent teleology is at work in them, not a design imposed from outside, but the end the concept gives itself in realizing itself. The whole precedes and orients the development of its parts.
Encyclopedia of the Philosophical Sciences, §204-212 (teleology)
Senecainferable
The whole universe is ordered by a acting toward an end, the good of the whole: nature does nothing at random and fate is the reasoned chain of causes toward that end. This is a providential , where the mechanical necessity of causes serves a rational design.

Marcus Aureliusinferable
Fate is the rational chaining of causes directed toward the good of the whole: causality is fundamentally , providential. The recurring atoms hypothesis nonetheless introduces a share of sheer mechanism, an alternative Marcus holds to be thinkable.

Socratesinferable
Disappointed by the natural philosophers who explain everything by material causes, Socrates recounts having hoped from that Mind ordered the world for the best, then finding him invoking only mechanisms. What he demands is explanation by the good, the end for the sake of which it is better that things be as they are: a finalism that turns philosophy away from nature toward value.

Charles Sanders Peirceinferable
Against the strict mechanism that sees in nature only rigid, necessary laws, Peirce upholds : chance is an objective reality, and laws are not given in advance but are habits that have formed and grow firmer in the course of an evolution. The cosmos has a history, it grows, and this growth is oriented by a tendency, evolutionary love or agapasm, which tips Peirce toward a finalist kind of explanation, while keeping the creative spontaneity that recalls vitalism. Far from the Cartesian machine, his nature is an organism in the making.
