If it appeared to be sneaky it's probably because of the way I phrased it! Reading it back it does sound like a kind of paradox but what I mean to say was when we look at something we're all generally faced with the same facts but usually come to very different conclusions. So why is that? If we based our conclusions on reason alone then we should all come to the same view but clearly we hardly ever do.
I think the question is controversial because it does suggest that there is limit to what reason or rationality can tell us about something. For example with addiction, can we ever find our way out using pure reason alone or do we at some point just have to accept that we really don't know what the best thing to do is but we nevertheless have to decide on a recovery method to adopt and we do this largely on an intuitive basis, on what feels most right for us?
