my posistion [sic] all along has a distinction between faith and rational belief
OK, but you are not using the term "rational" in the (what I thought was) the standard way. So the only reason what you're saying seems contentious is because of your terminology.
You have not yet addressed much of what I've written. Automatically rejecting everything that isn't 100% proven is a poor strategy if the agent's goal is to be right as much as possible, yet it seems to be the only one you insist is rational. Is this merely because of how you're using the word "rational," or do you actually recommend "Reject everything that isn't known 100%" as a strategy to such a person? (From the rice-and-gasoline example I think I know your answer already--that you would not recommend the skeptical strategy.)
How should an agent proceed, if she wants to have as accurate picture of reality as possible?
You are the only who is making assumptions without evidence and ignoring what I'm saying- that contrary to what you think you do not in fact know the Earth exists, your memories are reliable etc and therefore that your argument, which assumes such, falls apart.
You also fail to comprehend that probabilities have implicit axioms which must be accepted in order to accept probability. There is induction (e.g.- Sun risen X times already so it will probably rise again tonight), the Memory assumption (if my memories say I have done X then that is evidence in prob...
I've raised arguments for philosophical scepticism before, which have mostly been argued against in a Popper-esque manner of arguing that even if we don't know anything with certainty, we can have legitimate knowledge on probabilities.
The problem with this, however, is how you answer a sceptic about the notion of probability having a correlation with reality. Probability depends upon axioms of probability- how are said axioms to be justified? It can't be by definition, or it has no correlation to reality.
