What type of philosophy might be most useful during a nuclear war?

If you were to be so unfortunate as to find yourself stranded in a post-nuclear environment, I think there are certain philosophical resources in the history of philosophy that might be more usefully turned to than others. <br><br><br>If I think about the existentialists, they probably wouldn’t be useful in the sense that they would have the same inclination as most of us do to seek shelter somewhere and someone to protect us in such a situation. <br><br><br>But then there are others like Diogenes the Cynic and the Chinese hermit-scholars who were deliberately seeking out an ascetic way of life in complete solitude. <br><br><br>One thing about those ancients however is that they were living in conditions that were much different from what a nuclear war would unleash. If you look at the ascetic practices of those ancients, they were largely based on an intimate relationship with nature, living in forests and caves, foraging and gathering, working and living with the land, etc., which would no longer be possible in a post-nuclear environment.<br><br><br>Are there any philosophical teachings out there that could come into play when we have to abandon this relationship with nature?
