  • Others express confusion regarding the article's treatment of arguments versus conclusions, suggesting that it fails to adequately separate the two concepts.
  • One participant agrees with a critique of the article, stating that it does not provide new insights and overlooks the common fallacy linking invalid arguments to false conclusions.
  • Another participant points out that the article's conclusion seems to contradict itself by suggesting that arguments can be both true and invalid, or false and valid, which they find confusing.

Validity and truth do not have to go hand-in-hand and here's why...

Though I notice that the author starts out by saying
One common misconception among people is that an argument is immediately false if determined invalid (and vice versa).
but immediately switches to
There is distinction between the validity of a conclusion and whether the conclusion is true or not.

confusing the "argument" with the "conclusion".
 
yes, I have to say I agree with Hall's of Ivy, the article has told us nothing that wasn't known and fails to separate the argument from the conclusion (which is a common reson for the fallacy that because an argument is invalid the conclusion is false)
 
Yeah then he goes on saying,

"In conclusion, arguments can be true and invalid simultaneously. At the same time, they can be false and valid as well. Validity and truth concerning arguments are not dependent on one another so care should be made as to determining the truth of an argument based on the validity."

He jumped all over the place.
