This science is thoroughly intensional. It grounds the logic of inference on that in virtue of which the inference holds. It bases the truth conditions of propositions on relations between conceptual entities. It explains the logic of genus and species through the notion of essence.  Thom interprets this science as a formal logic of intensions with its own proof theory and semantics. This comprehensive reconstruction of Kilwardby’s logic shows the medieval master to be one of the most interesting logicians of the thirteenth century.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTrade Review\u003c\/b\u003e\u003cbr\u003e\"Robert Kilwardby (d. 1279) was almost always of interest to medieval philosophers. This interest, however, has seldom been replicated by modern editorial initiatives, leaving our appreciation of the Oxford master’s intellectual profile incomplete, and perhaps uneven. We are aware of the different contributions that Kilwardby made to metaphysics and to the natural  philosophy of his time, and we know that he was a dedicated and influential logician. We may even claim that Kilwardby was a fortunate logician, for he was one of the first scholars in the Latin West to read and to comment on the newly discovered books of Aristotle’s logic. This feature is greatly stressed in Paul Thom’s second book devoted exclusively to Kilwardby’s \"science of logic\", as described in the title.[...] Thom’s volume  already stands as a great and inspiring work for the almost timeless interpretative potential  he fairly attributes to Robert Kilwardby’s logic.\" Edit Anna Lukacs, in Speculum 96\/1 , (January 2021).\u003cbr\u003e\u003cbr\u003e\u003cb\u003eTable of Contents\u003c\/b\u003e\u003cbr\u003eAcknowledgements  List of Figures and Tables  Abbreviations   Introduction   1Logic as Science and Art   1 The Evolution of Logic   2 The Art of Logic   3 Branches of the Science of Logic   4 The Science of Logic as Sermocinal   5The Science of Logic Distinguished from Other Content in the Organon   6 Kilwardby’s Writings on Logic   7 Aspects of Kilwardby’s Thought   8 Formalisation   2 The Logic of Terms: Categories and Complex Terms   1 The Categories   2 Complex Terms   3 Formal Language   4 Models   5 Theorems   3The Logic of Terms: Relations between Terms   1 The Predicables   2 Genus and Species   3 Differentia   4 Proprium   5 Accident   6 Formal Analysis   7 Formal Language   8 Models   9 Truth in a Model   10 Postulates   11 Theorems   4 The Logic of Statements: Assertoric Statements   1 Propositions and Statements   2 Assertoric Statements   3 Truth   4 Ut nunc assertorics   5 Simpliciter Assertorics   6 Natural simpliciter Assertorics   7 Opposition and Equipollence   8 Conversion   9 Non-Aristotelian Consequences among Assertorics   10 Formal Analysis   11 Theorems   5 The Logic of Statements: Necessity and Possibility Statements   1 Modal Statements   2 Necessity Statements   3 Possibility Statements   4 Formal Analysis   5 Formal Language   6 Models   7 Theorems   6 The Logic of Statements: Contingency Statements   1 Unampliated Contingencies   2 Kilwardby’s Examples   3 Ampliated Contingencies   4 Kilwardby’s Rules for the Truth of Ampliated Contingency Statements   5 Kilwardby’s Examples   6 Formal Analysis   7 Theorems   7 The Logic of Inferences: Consequences   1 Consequences According to the Relations between Terms   2 Formal Consequences   3Pure Rules of Consequence   4Rules of Consequence and Conversion   5Rules of Consequence and Opposition   6Rules of Consequence, Opposition and Repugnance   7Rules of Consequence and Possibility   8Rules of Consequence and Assertion   9Rules of Consequence and Denial   10Essential Consequences   11Essential Consequence and Essential Inseparability   12Syllogistic Consequences   13Formal Analysis   14Truth Conditions   15Postulates   16Theorems   8The Logic of Inferences: Assertoric Syllogisms   1Syllogistic Figures and Moods   2Reduction   3Perfection   4Being Said of All   5Families of Syllogism   6Principles, Validity, Perfectibility   7Mixed ut nunc \/ simpliciter Inferences   8Summary   9Formal Analysis   10Generative Rules   11Theorems   9The Logic of Inferences: Necessity Syllogisms   1Family 3.
