My dad gives talks around our city. He is very “Spirit of Vatican 2”, pro-contraception and anti-hierarchy.
We got into a philosophy of religion discussion and he stated that Thomas Aquinas believed that if your observations of your world disagree with your religion you must change your religion. I asked him for the quote and context but he couldn’t give it but he has apparently been stating this as part of one of his talks.
Does anyone know where this might come from and where I could find what ever my dad might be referring to?
