You are right there, LotL. It is something that I notice in your comments.
However, your words of general wisdom do not help us here.
I am looking for clarification as to what your previous comment means?
In particular, what do you mean when you write:- "We are given rights to effect duties from our nature or from our vocation"? 
BTW, I am a professional translator, and so I do recognise the 'style', when I see it.
Thank you in anticipation.
