The biggest secret

Pseudo-Aristotle must be the most obscure author on Amazon. This is apparently an edition of “Secretum Secretorum” written in 16th century English. If you want a somewhat more readable version “translated” to modern English, I rather recommend Tarl Warwick's Kindle edition from 2016, on sale here under the title “Secretum Secretorum: Kitab Sirr Al-Asrar”. Or you might just go and do something else, because believe me, Pseudo-Aristotle is genuinely boring!
