3. E.g. P. Kingsley (unpublished thesis, Cambridge. 1979), O'Brien (1981), Wright (1981), p. 271. Van der Ben's position differs from mine in that he continues to operate with a strong distinction between what is properly‘ physics’ and what is properly‘ religion’. In moving material to the proem rather than the main thematic material of the physics, he is creating a further divide between proem (religious) and main books (physical) as well as that between Peri Physios and what remains for the Katharmoi.
