How does a person acquire ethical values?

Answer 1

Religious people will say it is gotten from God. Non religious people will say that they are taught to them by their parents.

Answer 2

To Acquire Virtues, either imply's you are a collector of Virtues looking to add another, or you have seen a Virtue, and by Relative Comparison, you are looking to acquire one like it. There is a old Argument, that Virtue is not something you can Acquire, either by Teaching or use of Money. The most Ancient of Thinkers Pondered just what Virtue was in the first place, that made one said to be Virtuous, Virtuous. Of course until such a time as one can actually identify Virtue by pointing to the Prime Example, perhaps the best one can do, is just stay within the laws, and common principles of Decent respect to all things living or not, but with Regards to the Question itself, seems to me, it would at least take a Virtue or two, to begin with, to want to seek more, so perhaps your inspiration itself, is the best test of your own Question.
