OK now we're getting somewhere. I like what this guy is on about. A bit from Wik below - but there is lots more on the wik page. I like this stuff, and wouldn't mind having a discussion about this further from those interested or who can express their own understanding of this philosophical perspective - and it's implications for life generally and personally.
This from Wik:
Sextus Empiricus raised concerns which applied to all types of knowledge. He doubted the validity of induction long before its best known critic David Hume, and raised the regress argument against all forms of reasoning:
Those who claim for themselves to judge the truth are bound to possess a criterion of truth. This criterion, then, either is without a judge's approval or has been approved. But if it is without approval, whence comes it that it is truthworthy? For no matter of dispute is to be trusted without judging. And, if it has been approved, that which approves it, in turn, either has been approved or has not been approved, and so on ad infinitum.
Because of these and other barriers to acquiring true beliefs, Sextus Empiricus advises that we should suspend judgment about virtually all beliefs, that is, we should neither affirm any belief as true nor deny any belief as false. This view is known as Pyrrhonian skepticism, as distinguished from Academic skepticism, as practiced by Carneades, which, according to Sextus, denies knowledge altogether. Sextus did not deny the possibility of knowledge. He criticizes the Academic skeptic's claim that nothing is knowable as being an affirmative belief. Instead, Sextus advocates simply giving up belief: that is, suspending judgment about whether or not anything is knowable. Only by suspending judgment can we attain a state of ataraxia (roughly, 'peace of mind'). Sextus did not think such a general suspension of judgment to be impractical, since we may live without any beliefs, acting by habit.
