Adglorium,
I am not a moral theologian, far from it.
But I would say it in two connected parts:
- We are owed the truth when we have a right to that information.
- And, crucially, we have a right to various types of information when we have a legitimate duty to pursue a good.
Rights should be thought of “things that help us do duties”.
I realize this seems like a perverse idea to most Americans, and I was struck by it when I first heard it explained this way, but it seems to carry water and also to get at the heart of the matter: to do good.
We have rights BECAUSE we first have duties (to seek various legitimate goods and ends, not just to seek our wants or curiosities).
If I am seriously starving I have a right to know where I can get food in order to live (which is to pursue a good)!.
If I am married, I have a right to know that my wife was injured and taken to this or that hospital, etc. I have a right to this information, in order that I may execute my duty to take care of her and to look after her (which is a good).
So my right (to anything, including the truth) has to be tied to a legitimate duty. And all duties need to be tied to true goods.
