There exists no generally accepted distinction.  But there are a few disnctions that people support.  Most notably is that Morality descibes interpersonal relationships, wheares Ethics is a quasi-scientific study of sysytems of morality.\n\nI think it was Kant who made my favorite distiction, that Morality is how I wish to be treated, whereas Ethics are how I wish everyone to be treated.  A difference of scale, if you will.
