All I can say is that I've reached my middle years without even realising I'd been completely deluded. Yes, I always thought I was reasonably intelligent (as much as the next person) but to realise you've allowed yourself to be totally deluded doesn't make you feel too good about yourself. Do I feel superior? Not at all! I also think most others on here feel that way too.
Maybe it would be interesting finding out what logic is but there's too many other interesting things to find out about to be bothered. Sorry!
