What can I know with 100% certainty? All I can advise you is to read my previous posts repeatedly — Corvus
This line you keep repeating reall could use a good inspection. If you're right about whatever you think you're right about, then this maybe gives off some sense of righteous superiority, BUT if you're wrong (and there's a lot of indications you are, if you care to pay attention to them), then... this thing you've said muliple times now, in different ways, takes on a very different tone.
You're demanding other people read your words on repeat until they come to agree with you, while yourself showing a general unwillingness to try to read and understand the arguments presented to you. There's a very narcisstic quality to this approach. And hypocritical, of course.
What would you think about a person on this forum arguing for something unambiguously untrue, like that 1 * 1 = 2 (thanks Terrence Howard), and they steadfastly held to that, and when someone disagreed for enough posts in a row, Terrence Howard says "Read my posts repeatedly until you understand that 1*1=2". How would that look to you?
That's how you look to us.
NOT, for the record, because you disagree with the cogito. That's fine. I don't care about that. Because of your misunderstanding of what the word 'therefore' does in logic, and because of your insistence on the validity of denying the antecedent, mainly.
1*1=2, read my posts repeatedly until you agree with me. That's what you look like to the rest of us when you make those points and say those words.
