In the modern world, goodness is generally understood as wanting others to be happy and not suffer. Sounds like the Golden Rule, as most people want to be happy and not suffer themselves, and goodness is understood as wishing the same for others. To be fair, it does look like a little bit of a narrow view, I remember Roger Scruton remarking that if your philosophy is equally suitable for humans and swine then you may need to rethink something (i.e. happy as a pig in the mud cannot really be the only terminal value, wishing it for everybody cannot be the only terminal goodness), but this is the social consensus today.
