 19111 Reasoning may be defeated by new premises, or by finding out more about the given ones
 19114 Should we accept Floating Conclusions, derived from two arguments in conflict?
 19113 Weakest Link Principle: prefer the argument whose weakest link is the stronger

 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 non-monotonic logic
###### 5. Theory of Logic / K. Features of Logics / 10. Monotonicity
 19110 In classical logic the relation |= has Monotony built into its definition
