8092 Logic was merely a branch of rhetoric until the scientific 17th century [Devlin]
2. Reason / A. Nature of Reason / 6. Coherence
17596 Coherence problems have positive and negative restraints; solutions maximise constraint satisfaction [Thagard]
17597 Coherence is explanatory, deductive, conceptual, analogical, perceptual, and deliberative [Thagard]
17598 Explanatory coherence needs symmetry,explanation,analogy,data priority, contradiction,competition,acceptance [Thagard]
3. Truth / A. Truth Problems / 6. Verisimilitude
17602 Verisimilitude comes from including more phenomena, and revealing what underlies [Thagard]
4. Formal Logic / A. Syllogistic Logic / 2. Syllogistic Logic
8081 'No councillors are bankers' and 'All bankers are athletes' implies 'Some athletes are not councillors' [Devlin]
4. Formal Logic / B. Propositional Logic PL / 1. Propositional Logic
8085 Modern propositional inference replaces Aristotle's 19 syllogisms with modus ponens [Devlin]
4. Formal Logic / B. Propositional Logic PL / 2. Tools of Propositional Logic / e. Axioms of PL
8086 Predicate logic retains the axioms of propositional logic [Devlin]
5. Theory of Logic / A. Overview of Logic / 1. Overview of Logic
8091 Situation theory is logic that takes account of context [Devlin]
5. Theory of Logic / A. Overview of Logic / 2. History of Logic
8087 Golden ages: 1900-1960 for pure logic, and 1950-1985 for applied logic [Devlin]
8089 Montague's intensional logic incorporated the notion of meaning [Devlin]
5. Theory of Logic / B. Logical Consequence / 7. Strict Implication
8082 Where a conditional is purely formal, an implication implies a link between premise and conclusion [Devlin]
5. Theory of Logic / E. Structures of Logic / 1. Logical Form
8072 Sentences of apparent identical form can have different contextual meanings [Devlin]

14. Science / C. Induction / 6. Bayes's Theorem
17600 Bayesian inference is forced to rely on approximations [Thagard]
14. Science / D. Explanation / 2. Types of Explanation / c. Explanations by coherence
17064 1: Coherence is a symmetrical relation between two propositions [Thagard, by Smart]
17065 2: An explanation must wholly cohere internally, and with the new fact [Thagard, by Smart]

14. Science / D. Explanation / 3. Best Explanation / a. Best explanation
17599 The best theory has the highest subjective (Bayesian) probability? [Thagard]
19. Language / C. Assigning Meanings / 1. Syntax
8073 How do we parse 'time flies like an arrow' and 'fruit flies like an apple'? [Devlin]
19. Language / D. Propositions / 2. Abstract Propositions / a. Propositions as sense
