Two questions. It seems that no one has figured out good standards for acceptance or rejection of philosophical arguments. In science, observation is king. If evidence contradicts a theory under careful conditions, the theory is false. In math, we justify things formally; we cannot expect more certainty. So would you agree that philosophy, as a field that aims at knowledge and not something else like evoking emotions, suffers from a lack of standards? And since at the moment I suspect it does, I want to ask also, why do philosophers act so certain? To them their arguments are true or correct (or whatever) without empirical evidence or rigorous proof. They should be the most uncertain people of all, even more so than scientists. And they are pretty darn humble.
(A better way to ask this might be, aren't proof and evidence the two best ways to knowledge? If so, shouldn't philosophers be much more uncertain than they appear (to me)? I now realize it's dependent on how I see things, so I only hope you can...
