PHL145H5 Study Guide - Final Guide: Hasty Generalization, Reference Class Problem, Inductive Reasoning
Document Summary
Chapter 8&10: general: arguments can offer two kinds of reasons for their conclusions, conclusive. If premises are true, the conclusion must be true: defeasible. If the premises are true, it is reasonable to believe the conclusion, absent further considerations against it: deductive argument: it aspires to validity. 2)it is logically possible for it to be invalid. 3) it is not a reason for dismissing the argument: strength is defeasible and degreed: an inductively strong argument can become weak when you add premises, and arguments can be more or less strong. 8: the strength of ss depends mainly on how large the sample is, using a different reference class may lead to another conclusion. Coverage (explain more of the given phenomenon than alternatives. Depth (do not require explanations themselves), power (explain in a wide range of related cases), falsifiable (not consistent with any possible event, they have predictive content), modesty (just enough content and no more), simplicity: ibe is defeasible.
