I'm sorry moshe, but I have to call bull on that article.
Right and wrong are aptly translated as el bien y el mal, and that is almost universally understood in the Spanish speaking community.
To imply that because a language doesn't have specific words to describe "right and wrong", that it therefore cannot know the concept of "right and wrong" is plain, flat-out stupid, and really this just smells of pseudo-science to me.
To see you identify with such a position..... tsk, tsk.
