To 'matter'; to have 'meaning'. All 'meaning' exists in the eye of the beholder. My eye couldn't care less what Jefferson thought or believed, so it doesn't 'matter' in the least, at this moment, from this Perspective! ;) As far as 'morality', isn't that the prideful sin of judging others, against which we are 'warned'? Besides, how to judge when no one actually has 'free-will/choice'?
