Doesn't moral goodness depend on our definition of moral goodness? For example, if we define "Good are those actions which upholds God's will, as in the Bible", our moral views are likely to be very different to those of people who define good as "Those actions which help, and do not hinder, others in achieving their own peaceful ends".
Yet how can we arbitrate between different definitions of the good? There are actions which uphold God's will, as presented in the Bible, and there are actions which help, and do not hinder, others in achieving their own peaceful ends, so how do we decide which of these groups of actions gets the label "good"?
