Depends how "old" the school of morality you're subscribing to is I guess and the strain of philosophy. Considering major Western Philosophies... New Testament circa 33AD not so much, pre-Enlightenment Catholic Church probably, Enlightenment era to pre-Marx, not so much, Marxist/Leninist and Progressive era of say 1900 and beyond then absolutely.
