All human beings by nature desire to understand. In The Aristotle Library, the works of Aristotle are read in full, that the listener may consider nature, virtue, reason, poetry, politics, and the first principles of things. For wisdom is not gained in haste, but by attending carefully to what is said, and by seeking the causes of what is.

  1. Episode 1

    Prior Analytics Book I Chapters 1-3

    In which the nature and rules of conversion in propositions, whether universal, particular, affirmative, or negative, are carefully examined with precise examples illuminating their interrelations. Further, this inquiry extends to modal propositions of necessity and contingency, discerning how their conversions align or differ by virtue of their modal qualities and logical form.

  2. Episode 2

    Prior Analytics Book I Chapters 4-5

    In which the nature and construction of syllogism are examined with particular attention to the first figure, revealing the conditions under which perfect and imperfect syllogisms arise from the relations of universal and particular terms. The discourse proceeds to the second figure, illustrating how the position and presence of the middle term affect the possibility and quality of syllogistic reasoning, especially emphasising the imperfection of syllogisms therein and the predominance of negative conclusions.

  3. Episode 3

    Prior Analytics Book I Chapters 6-10

    In which the nature and conditions of syllogisms in the third figure are intimately examined, revealing when such arguments hold necessity or fall short, especially in relation to the universality and affirmation or negation of their terms. It is further shown how all syllogisms, whether complete or incomplete, and those involving necessity, absolute, or contingency, may be ultimately reduced to or explained through the first figure, thereby uniting diverse forms of reasoning under a common principle.

  4. Episode 4

    Prior Analytics Book I Chapters 11-14

    In which Aristotle delicately examines the conditions under which necessity emerges in syllogistic reasoning, particularly in relation to affirmatives and negatives, and the interplay of universal and particular premises joined to a common middle term. He then proceeds to delineate the nature of contingency in propositions, distinguishing its forms and demonstrating how contingent syllogisms may arise, yet under certain configurations, may fail to yield conclusive results, thus preserving the subtle balance between necessity and possibility in logical discourse.

  5. Episode 5

    Prior Analytics Book I Chapters 15-16

    In which Aristotle examines the conditions under which syllogisms involving necessary and contingent premises yield perfect or imperfect conclusions, emphasising the roles of universal and particular propositions as well as affirmative and negative relations. He further delineates how necessity and contingency interplay within these logical structures, demonstrating that syllogisms are sometimes completed only through conversion, and that conclusions may be contingent, necessary, or inherently incomplete depending on the arrangement of terms.

  6. Episode 6

    Prior Analytics Book I Chapters 17-20

    In which Aristotle carefully examines the conditions under which syllogisms arise or fail when premises involve contingency, necessity, affirmation, or negation, demonstrating the subtle interplay of these modalities in the second and last figures. He elucidates that the nature of the premises—whether contingent, necessary, or simple—and their universal or particular status critically determine the possibility and form of valid syllogistic conclusions.

  7. Episode 7

    Prior Analytics Book I Chapters 21-25

    In which the nature of syllogisms is carefully examined through their various figures and modalities, revealing how necessity, contingency, and affirmation interplay to yield conclusions that depend fundamentally on universal premises and precise middle terms. It is further demonstrated that all valid syllogistic reasoning is reducible to three figures and invariably involves three terms and two premises, thus illuminating the essential structure underlying all demonstrations and logical discourse.

  8. Episode 8

    Prior Analytics Book I Chapters 26-30

    In which Aristotle elucidates the nature and complexity of syllogistic proofs, exploring the interplay of universal and particular affirmatives and negatives across various figures, revealing the relative ease of subversion compared to construction. He further expounds on the careful selection of premises and terms necessary for sound demonstration, illustrating how all syllogisms arise through the relations of consequents and antecedents, and concludes with reflections on the principle that demonstration in any art or science must be grounded in well-observed particulars and universal propositions.

  9. Episode 9

    Prior Analytics Book I Chapters 31-37

    In which Aristotle carefully examines the limitations of division as a method of syllogistic demonstration, highlighting how it often assumes what it ought to prove and fails to provide universal middle terms necessary for genuine inference. He then delineates the proper reduction of syllogisms into figures, explaining the significance of middle terms and the frequent illusions that arise from improper term explication and mistaken assumptions within propositions.

  10. Episode 10

    Prior Analytics Book I Chapters 38-46

    In which the subtle art of syllogistic reasoning is explored with careful attention to the placement and interchange of terms, the nature of hypothetical syllogisms, and the nuanced distinctions between affirmation, negation, and privatives. Through measured discourse, the text unravels how expressions and opposites relate, and how figures may be mutually transformed or remain distinct, revealing the delicate architecture of demonstrative logic.

  11. Episode 11

    Prior Analytics Book II Chapters 1-2

    In which the nature of syllogistic figures is examined with regard to universality and particularity, revealing how conclusions arise from the positions and relations of terms within propositions. Further, an exploration is undertaken into the truth-values of premises, demonstrating that true premises cannot yield false conclusions, while false premises may nonetheless produce true conclusions under certain configurations.

  12. Episode 12

    Prior Analytics Book II Chapters 3-4

    In which it is examined how truth may be inferred from premises that are wholly or partly false across different figures and syllogistic forms, with attention to the varied relations of terms through affirmations and negations. The discourse further contemplates the conditions under which conclusions hold necessity or possibility in respect to the truthfulness of their preceding propositions.
