These words and other ways you describe Diderot remind me of something I wrote: "I seek contentment, which is not settling but a hopefully high-altitude baseline, coming from within and connection to without. It doesn’t stem from the acquisition of attachments but awareness of connection to the world and the universe as a living, breathing, and heart-beating organism and from alignment of mind and soul."

Thank you for introducing me to this philosopher, of whom I had not been aware.
