Principle is a fundamental truth, rule, or proposition that serves as a foundation for reasoning, behavior, or systematic practice. Unlike derived rules or situational guidelines, a principle operates at the level of first cause within a domain: it is not inferred from anything more basic within that domain but instead generates and justifies the subordinate rules that follow from it. The mechanism of persistence is teaching and citation — principles endure through repeated application in reasoning, education, and institutional practice. [formal: principium | substrate: mind | horizon: a life | explicit: yes | epoch: 0.01]

Definition
Why it is in scope
A principle is a fundamental truth, rule, or proposition that serves as the foundation for a system of belief, behavior, or reasoning. It is human-made — a conceptual tool distilled from repeated observation, reflection, or formal derivation — built to persist through teaching, citation, and application across domains. Principles organize knowledge into actionable generalizations and guide decision-making.

INSTANCE_OF: a principle is a specific kind of rule — a fundamental or foundational rule that serves as a basis for reasoning, behavior, or systematic practice. A competent speaker would call a principle 'a rule'. Clean specific→general per Law 9.

A standard of proof IS a specific kind of principle — the rule specifying the required level of evidence (beyond reasonable doubt, preponderance, clear and convincing). Direction: specific→general. Note pins principle as a governing rule, not a vague norm.

The bias-variance tradeoff is a fundamental principle of statistical learning: increasing model complexity reduces bias but increases variance, and optimal performance requires balancing both. It is a general rule of thumb guiding model selection. A competent speaker in statistics calls it 'a principle.' Nearest kind is principle.

Equality IS a specific kind of principle — a normative standard for fair treatment and distribution. A competent speaker would call equality 'a principle.' Law 9: specific→general, and the sense is the political-philosophical sense of equality as a governing standard, per its accepted definition.
