I dunno Mooby...I do understand your arguments, and see the validity. Here are my problems.
1) I'm not a student of philosophy, so I'm not equipped to counter these arguments.
2) I find these arguments to be useful in an academic sense, but useless in a real-world scenario. I find no meaningful use in questioning whether I can trust my senses. I cannot function if I don't trust my senses, at least to the extent to which I've learned they're trustworthy (I know, for example, that "hearing things" is a possibility, and the human brain fills in gaps with patterns even when there are no patterns).
so, I have no problem conceding that the philosophical argument is beyond my capability to counter, but I choose to ignore the question because I think it's not relevant.
