4. Formal Logic / E. Nonclassical Logics / 1. Nonclassical Logics

We infer that other objects are like some exceptional object, if they share some of its properties

4. Formal Logic / E. Nonclassical Logics / 12. NonMonotonic Logic
19111

Reasoning may be defeated by new premises, or by finding out more about the given ones

19113

Weakest Link Principle: prefer the argument whose weakest link is the stronger

19114

Should we accept Floating Conclusions, derived from two arguments in conflict?

19118

People don't actually use classical logic, but may actually use nonmonotonic logic

19116

Nonmonotonic core: Reflexivity, Cut, Cautious Monotonicity, Left Logical Equivalence, Right Weakening

19117

We can rank a formula by the level of surprise if it were to hold

5. Theory of Logic / K. Features of Logics / 10. Monotonicity

In classical logic the relation = has Monotony built into its definition

19112

Cautious Monotony ignores proved additions; Rational Monotony fails if the addition's negation is proved
