@maxwelldunn89, I think to practice a moderate skepticism is good an healthy, but I am not sure whether in schizophrenia, and delusions specifically, a lack of skepsis is always the culprit. This may differ from person to person, but my experience with psychosis actually featured a lot of unhealthy skepticism, I take it. For while it is true that the delusions that troubled me were pretty much fixed and sure for me, I did not stop reflecting on my beliefs at the time. And doing so took the form of a thorough skepsis, aimed not so much at my delusions, though these were not entirely exempt from doubt, but all the more at everything else. For me it was not the case that I was simply not aware of my delusions being at odds with commonly held beliefs, many of which would easily pass as knowledge. Instead, whenever I would reflect on my delusions, I would notice this tension between them and these commonly accepted beliefs, and skepsis would turn on the latter. How did that common knowledge become so sure, what is the proof for it and can I be sure of that very proof in turn? As I am sure you are aware of, knowledge is quite complicated. A claim to truth is rarely exhaustively supported by a single further claim - instead it seems as if to support a single true proposition, one needs a vast network of other truths or assumptions to be in place. My psychoses would have me running through such networks of proofs and proofs of proofs endlessly, casting skeptical doubts on these and effectively tearing my world apart.
