>Everything might very well be an illusion - to prove that something is not an illusion, to prove that your senses do not lie, you would have to use your senses. Which is, again, circular reasoning.
This is YOUR problem, not mine. I can rely on my senses to know things, as I know that my senses are a reliable gift from God, you cannot rely on yours for the reasons you state. Tell me, how is it possible for YOU to know anything?
