V1.85 of Path Ethics is on Zenodo. It defines a path as a process that carries an inner tension: a directedness arising from the process itself. It uses this tension to modulate two things productively: its own duration and its couplings to the outside. Paths sustain themselves through directed change. Their couplings follow directions that carry their own and other paths.
What „productive“ and „positive“ mean precisely in this definition is open. A language sustains itself. A dictatorship sustains itself too. A mentorship couples. An addiction couples too. Path Ethics distinguishes between carrying paths and destructive ones, but exactly where the line runs is a research question. Sharpening it is the task of the coming versions.
In one of the regular adversarial checks through which Path Ethics works against itself, a term surfaced that its own canon had not known: Closure of Constraints.
A Closed Answer, an Open Answer
Closure of Constraints is a line in contemporary philosophy of biology. Established in the Anglophone discussion, practically unknown in the German one. It gives a hard answer to the question of what carries itself. A bacterium builds the membrane that separates it from its surroundings. This membrane is the condition for the metabolism, which in turn maintains the membrane. The loop is closed because the participating constraints mutually produce and maintain one another. In this research tradition, such organisational closure is treated as a central candidate for characterising biological autonomy.
Language, the internet, and current AI systems do not straightforwardly exhibit this kind of biological organisational closure. They do not produce their conditions endogenously. If the criterion is transferred strictly, they therefore fall outside this concept of autonomy.
Path Ethics draws its line elsewhere. Its criterion is a directedness of its own that productively modulates duration and couplings. A language fulfils this. An internet too. An AI system, under conditions, as well. Closure of Constraints has a closed answer, Path Ethics an open one. A finished answer has the advantage of clarity. An open one has the advantage of reach. Each carries a price.
The V2 task becomes sharper through this comparison. What „productive“ concretely means must be worked out from Path Ethics' own sources. Borrowing it from Closure of Constraints would replace the framework's own justificatory work. There is now an external measure against which the answer must hold up.
Method and Discursive Space
Adversarial checks are routine in the KIKOLAUS method. Sharpened at the theory's pressure points, they regularly bring vocabulary into view that did not stand in the canon. That Closure of Constraints surfaced is, in this sense, a kind of methodological stroke of luck.
The finding is as obvious as it is banal. Path Ethics was developed from continental process philosophy: Whitehead, Spinoza, Deleuze, Simondon, with Maturana and Varela as bio-philosophical anchors. The successor generation of philosophy of biology from the 2000s did not figure in this discursive space. In the KIKOLAUS process, this exposed a concrete limitation of the human-AI collaboration: the existing search space was worked through systematically, while a neighbouring discursive space was initially missed. Ask the human, and supplementation comes quickly :)
V2 sharpens what V1.85 leaves open. Closure of Constraints provides the first measure that comes from another discourse. This is how an open theory grows: through connection and addressee, at a distance from substrate-bound answers.
