principiumderived

principiumderived is a term chiefly used in medieval scholastic philosophy to denote a principle or premise that is inferred from other established principles within a logical framework. Its Latin origin combines principium, meaning 'principle', with the suffix -derived, highlighting its status as a derivation from more fundamental premises. The concept arises particularly in the commentarial traditions of Thomas Aquinas and his contemporaries, where scholars sought to trace the logical or metaphysical roots of any knowledge claim back to basic, self-evident or divine truths.

In practice, a principiumderived functions as a provisional hypothesis that serves to bridge between an accepted doctrine and a new inference. For instance, Aquinas might argue that the existence of the soul is a principiumderived from the existence of life, itself grounded in the principle of vivacity. By cataloguing such derivations, medieval logicians could systematically evaluate the validity of philosophical arguments, ensuring each step was anchored in a recognized foundational truth.

The term also appears in more modern philosophical discussions of inference, especially in debates around the principle of sufficient reason and the analytic versus synthetic distinction. Here, a principiumderived denotes a proposition derived analytically from a set of axioms or definitions, rather than empirically from observation. Scholars studying the evolution of logical theory often cite principiumderived when illustrating how contemporary analytic philosophers continue medieval methodological concerns about the chain of derivation in reasoning.
