DE FACTO and DE JURE
DE FACTO and DE JURE.—With some offences the penalty attaches to the offender at
the instant when the fact is committed; in others, not until he is convicted by
law. In the former case he is guilty de facto, in the latter de jure.
De facto is commonly used in the sense of actually or
and de jure in the sense of rightfully or legally; hence the philosophical use of
the terms. A de facto proof is a mere "natural history" of the facts; a
proof is a vindication of their existence; e.g., the principle of causality may
be proved de facto, i.e., it may be shown to be as a matter of fact accepted and
acted upon by men; or de jure, i.e., it may be shown to be the necessary
presupposition of the facts of experience, or of experience itself. This last is
the Kantian method of proof, called by him Transcendental Deduction.
