PHIL 210 Chapter Notes - Chapter glossary: Modus Ponens, Abductive Reasoning, Ad Hominem
Document Summary
Ad hominem: ( argument against the man ) choosing to attack the person making the argument rather than addressing the points raised in the argument itself. Addition: the valid argument form it is the case that p (premise 1). Therefore, it is the case that p or it is the case that q (conclusion). Affirming the consequent: an invalid argument in the form if p then q (premise 1). This invalid form is often confused with the valid form. Appeal to emotion: activating emotional responses such as fear, pity, anger or pride as a means of leading people toward the desired conclusion. Appeal to popular opinion: the mistaken reasoning that if enough people believe it, it must be true; holding the popularity of a belief to be sufficient evidence that it is true. Argument by dictionary: appealing to a dictionary definition as a means of settling a dispute.
