Our consciences are built upon, formed by the dynamic of experiencing the consequences of immoral acts, right?
No. At least, not in the way you’re conceiving of it (I think).
To say “conscience is formed by consequences of sin” would be misattributing the way in which conscience is formed. The Catechism tells us that “conscience is a judgment of reason whereby the human person recognizes the moral quality of a concrete act that he is going to perform, is in the process of performing, or has already completed.”
Judgments of reason do not proceed from experiencing consequences. Judgments of reason proceed from abstract thought. (Memories of consequences, on the other hand, might
aid in concurring with a conclusion that our conscience has already reached, but they don’t touch the conscience itself!)
So, if my conscience tells me that drinking alcohol to excess is sinful, then I’ve already analyzed the moral content of the situation. However,
I might still be attracted to that sin and want to commit it, even though I know it’s wrong. At that point, my memory of consequences of past instances of committing that sin (wasted money, dangerous acts I committed, the subsequent hangover) might cause me to decide to avoid committing the sin again. But – and this is the important point – that doesn’t mean that my
conscience is speaking… just my aversion to repeating negative consequences.
To deny this denies that people learn anything from experience.
I’m merely denying that “learning from experience” isn’t what conscience is all about.
(On the other hand, I might argue that the experience of negative consequences might lead me to examine the moral context of the actions that brought the consequences, and thus, rationally come to the conclusion that there’s an immoral act present. However, in that case, the consequence was only a
catalyst for the process of internal reflection and formation of conscience.
