Ancient Greek philosophy
John Lloyd Ackrill, (30 December 1921 – 30 November 2007) was an English philosopher and classicist who specialized in Ancient Greek philosophy, especially the philosophy of Plato and Aristotle. Ackrill has been said to be, along with Gregory Vlastos and G. E. L. Owen, "one of the most important figures responsible for the upsurge of interest in ancient Greek philosophy among Anglo-American philosophers of the second half of this century".
