"Henology (from Greek \u1F15\u03BD hen, \"one\") is the philosophical account or discourse on \"The One\" that appears most notably in the philosophy of Plotinus. Reiner Sch\u00FCrmann describes it as a \"metaphysics of radical transcendence\" that extends beyond being and intellection. It can be contrasted with ontology, as ontology is \"an account of being\" whereas henology is an \"account of unity.\""@en .
