2001: Rupert Woodfin [text], Judy Groves [illustrations], and Richard Appignanesi [ed.], Introducing Aristotle, page 24 (Icon Books UK, Totem Books USA; ISBN 1840462337)
The poet Thomas Gray said that reading Aristotle was like eating dried hay. This is something of an exaggeration, but his writing can be hard work. It is generally agreed that these “esoteric” (or “acroatic”) works are actually lecture notes, the working documents that he used on a daily basis for his teaching.
