What do you thing about what I claimed is a fallacy? Like, I think if you don't agree that your perception tells you about the truth, than you can also claim that you are a test tube brain and you won't be wrong. When there is no causality between what you are thinking and reality, your thoughts are just random ideas and don't mean anything. Heck, you don't even know causality exists, because you just don't know anything. I think this ideas are quite well expressed in: C.S.Lewis "On living in an Atomic Age". For example: https://www.andybannister.net/wp-content/uploads/2022/03/cslewis-living-in-an-atomic-age.pdf https://www.andybannister.net/wp-content/uploads/2022/03/csl... (I find it a bit easier to understand in my translation, but that may only be the fact, that english isn't my mother tongue.)
