Document Summary

An argument consists of a set of sentences consisting of one r more premises, which contain the evidence and a conclusion which is supposed to follow from the premises. *** what makes a good argument good is logical entailment. Bad arguments vs. good arguments: if the premises imply the conclusion, then the argument in question is a good one. If money grows on trees, then bill clinton is the prime. Thus, bill clinton is the pm of canada. (conclusion) ***symbolic logic-take out context and replace it with just a symbol. If both are true, then you cannot deny the conclusion on pain of consistency. You cannot deny the conclusion, if you accept the premises. An argument is deductively valid so long as the argument is such that the conclusion must be true if the premises are true. ***calling an argument valid, is paying it a compliment. If it is raining then there are clouds in the sky. (premise #1)
