PHL105Y5 Lecture Notes - Lecture 2: Modus Tollens, Lady Gaga, Hypothetical Syllogism
Document Summary
We can talk about the general form of those patterns (even before we evaluate the content of the statements themselves) In well-formed arguments, the truth of the premises would support the truth of the conclusion. (you don"t need to know whether the premises are actually true to know if the argument is well-formed). To evaluate an argument, you first have to look at the relationship between the premises and conclusion (later you can ask whether premises are actually true) The premises are supposed to give logically conclusive support to the conclusion. If the conclusion really does follow logically, given those premises, then the argument is valid. Validity is the form if good deductive arguments. In philosophy its not to a singular sentence, but a structure. In ordinary english, valid can mean several things (e. g. it can just mean reasonable or plausible, as in that"s a valid point you are making )
