addible

The commentary is primarily concerned with the nature of Number and in particular focused on defending from Aristotelian attack the Form numbers, "which must be regarded rather [than monadic or unitary numbers] as 'what it is to be Two, or Three, or Seven', are not addible (asumbletoi), and are not composed of undifferentiated units that can be added to or subtracted from them." For Syrianus, these Forms are creative principles in the universe and are themselves real essences.
