Incapable of Knowing
So if some people in the world are incapable of doing valid reasoning, and incapable of knowing that they are such people, my question to you is - how do you know that you aren't one of those people?! How do you know that right now you aren't in a mental hospital imagining everything you think is real?
You could argue that you have passed a sanity test, have a good job and good friends and that these things and people have all confirmed your sanity. However, how do you know that this isn't all part of your delusion?
Or you could argue that you may not know for sure that you aren't insane but that your reasoning seems to have worked for you so far. However, if you had a noisy neighbour you could shoot them, and this would "work" perfectly at stopping the noise, but clearly it would not be right.
If you are honest you will realise that you cannot know for sure that any of your reasoning is valid to any degree, which is absurd. The only way out of this circular nightmare is accepting revelation from God.
(Note - I'm not saying you are insane. I'm pointing out that without God you cannot justify any of your reasoning being valid.)

Things get worse
Not only do you have the massive problem of not being able to know anything because of the vicious circle of using your reasoning to validate the validity of your reasoning, but you also have a massive problem related to the uniformity of nature. (Click below).
