In the Book of the Two Pieces of Advice, a diatribe against false knowledge, ‘Abd al-Latif presents “two pieces of advice” for would-be physicians and would-be philosophers, an impassioned polemic against false physicians, and an equally harsh invective against false philosophers (see Gutas 2011; Martini Bonadeo 2013; Joosse 2014; Fedouache - Ajoun - Ben Ahmed 2018).
