By the way, just the actually answer the question:
It is permissible for a Catholic to be what is called an equiprobablist.
There’s not a lot of information about this on the internet, so excuse me for quoting from Wikipedia:
This basically is the view of St. Alphonsus de Ligouri, who’s really the preeminent Catholic moral theologian. “Opinions” references the views of the Doctors or other moral authorities.
In our case, I’m not sure that the view that learning foreign languages is sinful is
ever mentioned by **any **Catholic authority. Therefore, even the condemned rigorist position would permit it, let alone something more sound like equiprobablism.
But to learn more, you’d need to consult with a priest with a solid background in moral theology. I’m not sure we can be of much more help.

Oh, I think you’ve done tremendously in helping me to wrestle with this question, and I truly appreciate it!
However, I do admit that I certainly don’t have a formal background in Catholic moral theology (that’s probably way down the line for me at this point!), so do forgive me ifI show any ignorance on what may be to you obvious points.
So, is “law” in your quotation referring to Mosaic law, to moral/divine law, to natural law (the definitions ofthe latter two terms I am indeed still trying to wrap my head around)? I’m just wanting to be sure that its context is as close to ours as it can be so that any transference ofmeaning may not further problematize the situation.
So, then, implicitly, with this quote, you are making the claim that the statement, “It is wrong to learn foreign languages,” falls under of a questionable divine)?)/moral)?) law, correct? (I was going to say, “, no?” or “, nonne?”, but that doesn’t sound good in English…Wish we had something like that in our language, but that’s for another day.

) You claim this even though the implications which may be derived from our Genesis passage may rather strongly point to the correctness of the above statement? You (or, I should say, at least aequiprobablism) claim)s) that a position is less probable if there has been no Catholic teaching concerning the positivity of the statement? How can one draw this conclusion? Would you mind please explaining how the aequiprobablist position might specifically apply to our current discussion?
You seem a very thoughtful person whose opinions could carry a lot of weight, so I’m also interested in whar your own personal thoughts are about this situation. Do you support an aequiprobablist position, a rigorist one, etc.? Could you perhaps elaborate on it based on our current topic under discussion?
Finally, I suppose that, while I may be made somewhat more comfortable with an affirmative stance on learning foreign languages based on probabilities, there is still, by the very nature of probability, some, even remote, chance my position may be incorrect. I guess I’m trying, if possible to discover 100% certainty in this matter and, if not, to come as close to certainty as I can about it.
Again, thank you so very much for all your help!
P.S. Please do forgive me if I use certain terminology in a rather loose (or even incorrect) way above! As I say, I almost certainly do not have the kind of background you do on these subjects.
