Document Summary
10 most important concepts from chapter 1 & 2 hurley a concise introduction to logic: arguments, non-arguments, deduction. Induction: evaluation of arguments, extended arguments, language. Purpose: develop methods & techniques to distinguish good from bad arguments. One or more premises provide support, or reason to believe the conclusion.
