John Dillon has reviewed (very positively) the recent Plotinian study by J.-F. Pradeau. Of special interest might be Chapter 8 on ‘The One: First, Ineffable, Ungraspable’, which approaches Plotinus’ fascinatingly apophatic take on the first principle as well as delving into its modern Nachleben among the likes of Bergson and Levinas.
