PHIL 1101 Lecture Notes - Lecture 2: Ad Hominem, Practical Reason, Proctor
Document Summary
Rationalizing: genuinely, rather than a speciously, reasonable thing to believe or do (green 13). In other words: an argument tries to show that it"s rational to hold some claim (by structure, truth and structure, or degree of plausibility) -what it"s made of: premises and a conclusion. Valid:(14) if the premises are true, then the conclusion must be true as well :more strongly, there"s no way where the premises could be true and get a false conclusion. If the premises are true, the conclusion must be true/could not be otherwise. Ex: all mythical creatures are cool, nessy is a mythical creature, therefore nessy is cool. Eats onions, they"ll have smelly breath. my brother just ate onions. Invalid: (15-6) if there"s a situation where the conclusion is false while the premises are true/if there"s room for another conclusion, it"s invalid. Ex: places that don"t have windows are dark. i guess that means that.
