abstract
- The deductive-inductive distinction and the linked-convergent distinction apply primarily to support of conclusions by premisses. Such support is conclusive if and only if the argument has a true or otherwise acceptable covering generalization that supports counterfactual instances. Probabilification is only one type of non-conclusive support. To determine whether and how the premisses of an argument support its conclusion, it is best to make minimal changes and additions to the stated argument.
