Found this is a review of Pierre Hadot where he uses it how Michel Foucault has used it. While wikipedia will tell you it is scholarly essays written by the ancients, Foucault focused on the style more precisely: ” The hypomnemata constituted a material memory of things read, heard, or thought, thus offering these as an accumulated treasure for rereading and later meditation. ” In this way, Marcus Aurelius Meditations is Hypomnemata as it is a personal record of accumulated treasures. Sometimes these treasures are used in essays or speeches to persuade the the public in some way (the focus of wikipedia’s definition). but the more interesting part to me is the personal nature of the collection of wisdom. My blog is hypomnemata.
