2. Reason / E. Argument / 1. Argument
19115

You can 'rebut' an argument's conclusion, or 'undercut' its premises

4. Formal Logic / E. Nonclassical Logics / 1. Nonclassical Logics
19119

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?

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

19118

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

5. Theory of Logic / K. Features of Logics / 10. Monotonicity
19110

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
