I was wondering if the idea of paskening applies to the de'os area of Torah.
As an example there is a machlokes rishonim how to view Chazal's relationship with the science they relied on to pasken on certain issues. Some rishonim say that "nistaneh hatevah" which means that the science they relied on was correct however things have changed (evolved?) since then so our science produces different conclusions. Other rishonim say that they were relying on the science of their time which was a correct thing to do despite the fact that in reality their science was incorrect. Is there an idea to pasken how to view Chazal in this area?
(Just to clarify, I am not asking about de'os that actually have an impact on halacha lema'aseh in terms of how we act.)
Open to all ideas but appreciate sourced ideas the most.
