Chrizum said: While LordTheNightKnight is taking this much too far (as always), he is right about the "opinion disucssion". You can't just slap "IMO" or "I think" in every sentence and say "It's my opinion so it can't be wrong".
It's funny because I'm currently taking a philosophy class called "Logic" and we discuss how arguments can be verified and falsified.
"I like trees better than grass because trees are red and grass is yellow which is ugly IMO" is easily falsified. Yes, it's an opinion, but it's still wrong.
In short: an opinion based on a false premise is an invalid opinion. |
Whoa, no: a factually true proposition can be deduced from a factually false premise
(factually false) premise A: "all men are reptiles"
(factually true) premise B: "all reptiles are mortal"
formal deduction from A and B: "all men are mortal", which is factually true.
In terms of your logic class: the table of truth value for "false=>true" is true
In short: even if the guy's premises are weak, and his reasoning is a mess, the conclusions he comes to must be disproved for their content, not for the process. Which isn't hard, mind you.
