"Who shall decide when doctors disagree, And soundest casuists doubt, like you and me?"

This quote by Alexander Pope is a reflection on the difficulty of making choices when there is argument amongst experts. It suggests that even the most educated and experienced individuals can disagree on a particular problem, and that it can be difficult to decide who is right. The quote indicates that, in such cases, it is up to the private to make the decision, as even the most competent casuists (professionals in the application of laws and principles) can doubt and disagree. This quote is a pointer that, even when faced with contrasting opinions, we should make our own decisions and take obligation for the consequences. It is a reminder that, even when experts disagree, we should trust our own judgement and make the best decision we can.
