4. Formal Logic / E. Nonclassical Logics / 2. Intuitionist Logic
18832 Mathematical statements and entities that result from an infinite process must lack a truth-value [Dummett]
10. Modality / B. Possibility / 8. Conditionals / a. Conditionals
13768 Validity can preserve certainty in mathematics, but conditionals about contingents are another matter [Edgington]
10. Modality / B. Possibility / 8. Conditionals / b. Types of conditional
13770 There are many different conditional mental states, and different conditional speech acts [Edgington]
10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
13764 Are conditionals truth-functional - do the truth values of A and B determine the truth value of 'If A, B'? [Edgington]
13765 'If A,B' must entail ¬(A & ¬B); otherwise we could have A true, B false, and If A,B true, invalidating modus ponens [Edgington]
14. Science / D. Explanation / 3. Best Explanation / a. Best explanation
14790 'Abduction' is beginning a hypothesis, particularly if it includes preference of one explanation over others [Peirce]
14791 Abduction involves original suggestions, and not just the testing involved in induction [Peirce]
