Moral Compass Project

How do we know what the Good is? Is there such a thing as a ‘moral compass’ that all people share? The needle of a compass points to the north pole, but you can't reach the pole with it. Can the Good also be seen as such a pole? As something that speaks to us 'from the outside,' inescapably? The Good appeals to us in a way that gives us direction and encourages us to take concrete action. But that does not imply we are able to fully know or do the Good.
