Ancient Egyptian philosophy refers to the philosophical works and beliefs of Ancient Egypt. There is some debate regarding its true scope and nature. Notable works One Egyptian figure often considered an early philosopher is Ptahhotep. He served as vizier to the pharaoh in the late 25th, early 24th century BC. Ptahhotep is known for his comprehensive work on ethical behavior and moral philosophy, called The Maxims of Ptahhotep. The work, which is believed to have been compiled by his grandson Ptahhotep Tjefi, is a series of 37 letters or maxims addressed to his son, Akhethotep, speaking on such topics as daily behavior and ethical practices. Dag Herbjørnsrud, writing for the American Philosophical Association, describes the 3200-year-old manuscript "The Immortality of Writers", or "Be a Writer" (c. 1200 BC), as a "remarkable example of classical Egyptian philosophy." The manuscript, attributed to the writer Irsesh, states: Herbjørnsrud writes: "In 2018, projects are under way to translate several ancient Egyptian texts for the first time. Yet we already have a wide variety of genres to choose from in order to study the manuscripts from a philosophical perspective: The many maxims in “The Teaching of Ptahhotep”, the earliest preserved manuscript of this vizier of the fifth dynasty is from the 19th century BC, in which he also argues that you should “follow your heart”; “The Teaching of Ani”, written by a humble middle-class scribe in the 13th century BC, which gives advice to the ordinary man; “The Satire of the Trades” by Khety, who tries to convince his son Pepy to “love books more than your mother” as there is nothing “on earth” like being a scribe; the masterpiece “The Dispute Between a Man and His Ba” of the 19th century BC – in which a man laments “the misery of life,” while his ba (personality/soul) replies that life is good, that he should rather “ponder life” as it is a burial that is miserable – recently discussed by Peter Adamson and Chike Jeffers in their “Africana Philosophy” podcast series. Or we can read Amennakht (active in 1170–1140 BC), the leading intellectual of the scribal town Deir El-Medina, whose teaching states that “it is good to finish school, better than the smell of lotus blossoms in summer.” Influence on Ancient Greek philosophy Several of the ancient Greek philosophers regarded Egypt as a place of wisdom and philosophy.
