They think that if my argument is invalid, that it is untrue. Not so.
Very much to the point.
Yes an argument can be invalid but true: the problem is that the truth can not be inferred from the logic but just happens to be so externally (probability low because it is coincidentally so, or probability okay because it is likely so due to other factors not included in the argument).
What this is in essence saying is "let's all try again, with feeling ... when it comes around on the guitar ...")
I don't know if you've seen it but there is a new site that was linked here on logic constructions and evaluations. It is TruthMapping.com
http://www.truthmapping.com/index.php
And really forces you to use the premise\premise\conclusion format, with ready critique of any mistakes, assumptions and false premises
(btw - a falsified premise does invalidate the conclusion ...
)
