^{page 401 Note 1} We should like to enter a protest against the word ‘Canonice’ which stands as the chapter heading here. How is the English reader to know how to pronounce this word? Two German universities have allowed theses to go out under the title De Epicuri Canonica, which is at least better by the letter a for e Usener has a section headed ‘Canonica,’ but this is neuter plural (see footnote, Epicurea, p. 177). It is true that Diogenes gives the Epicurean division of philosophy (x, 29) as κανoνικóν, φυσικóν, ἠθικóν, but the form κανoνικἠ does not seem to occur, and actually, as Diogenes tells us in the same passage, the theory of the κανών was considered to be a part of ‘physiology.’
