In al-Radd ala al-Mantiqiyyin, Ibn Taymiyya (d. 728/1328) asserts that analogical inference (qiyas al-tamthil) and categorical syllogism (qiyas al-shumul) are epistemically equivalent: where one yields certainty or mere probability, so does the other. The claim has been reported for a century of modern scholarship, from Hallaq onward, yet never subjected to formal examination. This book offers the first published formal audit. Working within the monadic fragment inhabited by Aristotelian assertoric syllogistic, and reading the universal premise intensionally — as Ibn Taymiyya explicitly does — the study establishes: (1) the equivalence and interconvertibility theses hold as semantic theorems: the two forms share a single class of countermodels, and the cited exemplar is deductively idle; (2) the exemplar is nonetheless warrant-bearing — every route to knowing the universal premise passes through witnessed particulars, a point Ibn Taymiyya states almost verbatim and which appears in Aristotle's own account of paradigm (An. Pr. II.24); (3) his sole exception, universals known by infallible report, is derivable from the very structure of the claim; (4) the Aristotelian taxonomy of demonstrative matter self-destructs when asked for the warrant of its own universals; (5) the declared price: ultimate warrant migrates from logic to theology. Neither an empiricist precursor of Mill (contra Hallaq) nor a claimant "vindicated" by modern logic, Ibn Taymiyya emerges as author of a theory of where formal validity ends and warrant begins. In Arabic.
