Distinctions Between Logical Invalidity and Falsity

In summary, the conversation discusses the misconception that an argument is automatically false if it is determined to be invalid. The author argues that there is a distinction between the validity of an argument and the truth of its conclusion. They also mention that an argument can be true and invalid, or false and valid, and that validity and truth are not necessarily dependent on each other. The article ultimately highlights the importance of carefully considering the truth of an argument based on its validity.

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.
 

1. What is the difference between logical invalidity and falsity?

Logical invalidity refers to a statement or argument that does not follow the rules of logic and therefore cannot be considered valid. Falsity, on the other hand, refers to a statement or argument that is not true or is intentionally deceptive.

2. Can a statement be both logically invalid and false?

Yes, a statement can be both logically invalid and false. This means that not only does the statement fail to follow logical rules, but it is also not true.

3. How can one determine if a statement is logically invalid or false?

To determine if a statement is logically invalid, one must examine the structure and reasoning behind the statement. If it does not adhere to the principles of logic, it is considered invalid. To determine if a statement is false, one must evaluate the truthfulness of the statement based on evidence and facts.

4. Are there any consequences to using logically invalid or false statements?

Yes, using logically invalid or false statements can lead to faulty reasoning and misinformation. It can also undermine the credibility of the person making the statements and can have negative impacts on decision making and problem solving.

5. How can one avoid using logically invalid or false statements?

To avoid using logically invalid or false statements, one must practice critical thinking and carefully evaluate the evidence and reasoning behind any statement before accepting it as true. Additionally, one should be aware of logical fallacies and avoid using them in their own arguments or statements.
