Proportionality is the normative principle that a response, classification, or constraint should be scaled to match the gravity of its cause — the offense, the risk, or the evidence. It carves three parameters: (1) the stimulus (act, threat, or fact), (2) the response (sanction, measure, or judgment), and (3) the scaling rule (balance, equivalence, or necessity) that connects them. Without any one parameter the concept collapses: no stimulus means no trigger, no response means nothing to calibrate, no scaling rule means brute force or whim. Proportionality persists through legal codification (statutes, constitutions, case law), ethical teaching (utilitarian and deontological frameworks), and institutional practice (sentencing guidelines, use-of-force policies). It is a standard of review as much as a rule — judges weigh proportionality; institutions design for it. [formal: proportio | substrate: mind | horizon: generations | explicit: yes | epoch: 1.01]

Definition
Why it is in scope
A human-made calibration principle used across law, ethics, and institutional practice to match the magnitude of responses, sanctions, or classifications to the gravity of their cause. Persisted through codification, teaching, and institutional reasoning.

Proportionality requires measurement to operate now — a proportional relationship is meaningless without the ability to measure quantities. Remove measurement and proportionality cannot function. This is constitutive, not merely historical.

Proportionality IS a specific kind of principle — the requirement that a response be proportional to a goal or offense. It appears across law, military ethics, and physics. Law 9: specific→general.

proportionality is designed and maintained for the sake of justice — in law, military ethics, and penal theory, the requirement that response match offense exists to serve the operation of just outcomes. Servant (proportionality) points to master (justice). Law 8d.

Proportionality is designed and maintained for the sake of law — penal theory, sentencing guidelines, and constitutional review all require proportional responses. The concept exists to make law's enforcement defensible and predictable. Law 8d: servant→master, clear teleology.

Linearity as a mathematical/system property was derived from the ancient concept of proportionality — the homogeneity part of linearity (f(ax)=af(x)) is the generalization of proportionality from scalars to functions. Which-came-first: proportionality is ancient (Euclid's Book V), linearity as a formal property came much later.
