"Iamblichus set out to give a systematic and decisive character to Plotinus' dialectic at its most sublime but also most obscure moment, that of absolute unity and its forms, already dealt with by Amelius and Porphyry; that is, around the way of reconciling and harmonising the mystical theory of the One with the variety of unitary principles that are expected to preside over the various aspects of life: that is, the transcendent One and the immanent One, the unity of thought and being, thinking thought and thought thought, and finally thought as an intelligible world. (La Scuola di giamblico, “'School of Iamblichus”', XXX, p. 187)"
