"You don't know there's no hell - and there's no way you can be certain - because you've never been there!"
Is that really a trump-card argument that should stymie an Epicurean into saying, "Well gee I guess you're right!" ![]()
No I don't think so.
Nor is it sufficient as a general rule to say "We can never be sure of anything. Life is only a matter of probabilities." [Yes that's sufficient for those who are committed to be professional skeptics. I have to wonder how large a percentage of the world's population that is. I doubt it's 10% and it's probably a lot less.]
And if those aren't sufficient answers, and if Epicurean philosophy is open to and can be grasped by everyone who is of normal intelligence (as I think we all agree, which applies to everyone expect possibly very small children and those with true mental issues) then we have to be able to articulate an understandable theory of what it means to know something -- just as it appears the ancient Epicureans were doing in rebelling against Socrates/Plato and Pyrrho.
