'Yes, I used my reasoning'

You used your reasoning to try to give an answer to the question 'How do you know your reasoning is valid?'
So you are basically saying 'I reason that my reasoning is valid'. This is viciously circular and absurd. You are reasoning that your reasoning is valid, and therefore have no way of justifying ANY knowledge, thus confirming what I said on the home page - If you don't start with God you can't know anything.
Even if you say that you are relying on science and other people's collective reasoning, you still have to use your own reasoning to interpret what others are telling you. (As well as assuming that what they are saying is true, which often is not the case). So you are still left unable to know how your reasoning is valid and stuck in the bind of circular reasoning. I'm sure that you would not accept what I said if I just said, God is true because I know God is true. That would be fallacious. (That's not my argument by the way - the argument is: I know God is true by revelation from God AND if you deny God you cannot know anything to be true.)

Are there some people in the world who are incapable of valid reasoning?
The next question I'd like you to think about is: Are there some people in the world who are incapable of valid reasoning? (People whose minds are so damaged that they are not able to reason validly about anything in order to come to correct and logical conclusions about things, for example, some severe cases of insanity.)
Yes, I accept that there are some people in the world who are incapable of using valid reasoning about anything
