18781 Inconsistency doesn't prevent us reasoning about some system [Mares]
4. Formal Logic / E. Nonclassical Logics / 2. Intuitionist Logic
18789 Intuitionist logic looks best as natural deduction [Mares]

18792 Situation semantics for logics: not possible worlds, but information in situations [Mares]

18788 For intuitionists there are not numbers and sets, but processes of counting and collecting [Mares]

3978 Associations are held to connect Ideas together in the way the world is connected together [Fodor]
15. Nature of Minds / B. Features of Minds / 4. Intentionality / b. Intentionality theories
3976 Intentional science needs objects with semantic and causal properties, and which obey laws [Fodor]
