Well referenced and comprehensive - I'd like to use this essay as a reference-point for my own exploration, and thank you for introducing me to Caillé!
'...Caillé et al. (2014, p. 30) use ‘convivialism’ “to describe all
those elements in existing systems of belief, secular or religious, that help us identify principles
for enabling human beings simultaneously to compete and cooperate with one another, with a
shared concern to safeguard the world and in the full knowledge that we form part of that world
and that its natural resources are finite.” '
You and I touch on similar aspects, but I like the "conviviality" approach. I think there is somewhat of a parallel in Paul Ricoeur's idea of "solicitude", which forms the second consideration in his petite éthique ie "to aim to live with and for others in just institutions".
