I was thinking about that phrase “raison d’etre” this morning. Reason for being. Looked up the origin -

“Philosophically, it connects to existentialist and teleological (purpose-driven) thought. Existentialists like Jean-Paul Sartre argued that humans must define their own raison d’être because life has no inherent meaning. In contrast, religious or spiritual views might say that a raison d’être is given by a higher power or a natural order.”

I think both are valid and needed.
