I love a good rabbithole but the Wikipedia articles for very basic concepts are so so interesting too. the page for “War” is of course incredibly developed and thought out, deeply exploring its history, types, effects, motivations, ethics, and mitigation with lotsss of interesting jumping off points for other philosophical, historical, material, and sociological topics. not reccing this in an edgelord way but in a sober and curious way
