Proving something isn’t the same as something being true. I agree you can’t prove something with flawed logic. That doesn’t make the statement true or false though. That exists independently of a persons ability to prove it. The laws of nature are going to govern the world whether or not anyone can prove that they exist.

We need to be careful not to confuse proving something with whether or not something is true. I agree with the article’s point that someone can make a statement that is truthful whether or not they used proper logic to come to that conclusion. Where I differ from the article is that I don’t believe that the person is guaranteed to be right about anything else, nor would I believe that their logic is valid.
