Alrighty, I'll accept that.
No, actually. I was thinking more broadly to the universal human inclination, as outlined in your post #535.
I used the word 'institution' for lack of a better term. We are speaking of social indoctrination, and although that starts at the family level, societal norms are transmitted through the entities you reference, including religions, political institutions, educational institutions, Philosophy, and Science, all of which you reference in post #535.
So, however you want to label the organizations or entities that transmit and indoctrinate beliefs, my questions is whether any of them recognize the problem you describe as the innate human inclination to be closed-minded, and it seems above that you feel religions do, although ineffectively. You have discounted the other listed entities for various reasons, including science.
I am fascinated that you think religions in general recognize and address the problem. It would seem to me, for any of these institutions or entities to have a chance at combating closed-mindedness as we have been describing, they would have to be open to continual reevaluation of every one of their stated beliefs. I do not see that happening in religion in general, or overall. Perhaps you have in mind a specific subset or denomination of religion that maintains sufficient skepticism at its core to accomplish it. I have yet to come across such.
Science, on the other hand, I see as having this idea of continual reevaluation at its core, yet you dismiss it as too practical, whatever that means. I can only conclude that you have too narrow a working definition of what science is. To my mind, it is simply an endeavor for knowledge acquisition that acknowledges human flaws and fallibility, and actively works to mitigate those flaws and fallibilities in the knowledge acquisition process. It matters not what the subject matter is, if human fallibility is accounted for and actively mitigated, such as the innate closed-mindedness we have been describing, then it is being done in a scientific manner. I just do not see similar mechanisms for mitigating human fallibilities in either religion or philosophy.
