Along with being, truth, and goodness, the one (unum) is one of the main attributes used of God in Christian tradition. In his Being and Some Philosophers, Etienne Gilson devoted a chapter to “On Being and the One,” arguing that being (esse) is the root of unity, rather than the other way round. This talk will address the thinkers Gilson studied in this chapter from Plato to Eckhart, suggesting that a “polyphonic” approach to language about God, one in which all the attributes interact, is more helpful than a “monophonic” approach in which one attribute has dominance over the others.
