the human race didn't have these things there could never be a society because there wouldn't be a solid base to create anything. Therefore I believe that David Hume supports moral universalism over moral relativism because moral universalism never changes, as to moral relativism can change based on culture or religion. Moral universalism is the solid bases that never changes because it is human nature. For instance ambition is the single thing drives society because with ambition people have the motivation to build cities and create a society. With generosity people extend an open hand to help others in need because it's the right thing to do, because it is human nature. How ever if it were moral relativism it could be a different because it's based on different views and culture. So for instance if a certain culture did not believe in generosity or ambition because it wouldn't be morally acceptable in their culture they would have a difficult time building a sustainable society, because these morals would go against their human nature and would have to be taught to them.
Therefore I believe that Hume’s view supports moral universalism because he talks about how man's ethics remain the over time because it's human nature. Versus moral relativism is something that someone is almost taught or brought is up in a certain way because it's culturally based, therefore there are different views on things on how someone is raised.
