The Precepts have a distinctive style and format that is largely determined by their nature as described above. In identifying the notable features of their style, it is important to start just from the evidence provided by the extracts explicitly identified as from the Precepts by Stobaeus. These stylistic features can then be used to help identify passages in Iamblichus’ On the Pythagorean Way of Life that derive from the Precepts even though Iamblichus does not explicitly identify their source.
