Distinctions Between Logical Invalidity and Falsity

AI Thread Summary
Validity and truth are distinct concepts in logical arguments, meaning an argument can be invalid while still reaching a true conclusion, or valid while leading to a false conclusion. The discussion highlights a common misconception that invalid arguments must have false conclusions and vice versa. It emphasizes the importance of separating the validity of an argument from the truth of its conclusion to avoid logical fallacies. The article referenced fails to clarify these distinctions effectively, leading to confusion. Understanding this separation is crucial for accurate logical reasoning.

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.
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
