Soul is the lowest of the Divine hypostases. Below it in the scale of values is the material universe to which its lower activities give form, slumbering in the rocks and dreaming in the plants. In plants, says Plotinus, “the more rebellious and self-willed phase of soul is expressed”: a doctrine which will find an echo in many a gardener’s heart. The sensible beauty of the world is the signature of soul, and points to something “Yonder”; for through loveliness it participates in the world of spiritual values, and we in apprehending beauty turn away from matter to _Nous_ (I. 8. 4). Matter, as such, has no reality except as the stuff from which soul weaves up its outward vesture. Deprived of soul, it is in itself, he says, “not-being” and “no-thing”: “its very nature is one long want” (I. 8. 5). As a picture is the crude and partial condensation of an artist’s dream—all that he can force his recalcitrant material to express—so the physical world is but a fragmentary manifestation of the great and vivid universe of soul, and the body is the smallest part of the real man. When we grasp this, we see how great is the sum of possibilities opened to us by the Cosmos; how easily the country “Yonder” can find room for all the visions and intuitions of artists, poets, and saints. The Plotinian doctrine of man, which became in due course the classical doctrine of Christian mysticism, is the logical outcome of this cosmology. Man, like the rest of Creation, has come forth from God and will only find happiness and full life when his true being is re-united, first with the Divine Mind, and ultimately with the One. “When the phantasm has returned to the Original, the journey is achieved” (VI. 9. 11). Hence “our quest is of an End, and not of Ends. That only can be chosen which is ultimate and noblest, that which calls to the tenderest longings of the soul” (I. 4. 6). As the descending stages of reality are three, so the stages of the ascent are three. They are called in the Enneads purification, the work of reason, which marks the transference of interest from sense to soul; enlightenment—the work of spiritual intuition—which lifts life into communion with the eternal world of spirit; and ecstasy, that profound transfiguration of consciousness whereby the “spirit in love” achieves union with the One. These stages are familiar to all students of Christian asceticism, as the codified “mystic way” of purgation, illumination, and union: a formula which Dionysius the Areopagite took from the Neoplatonists. But it is important to remember that in Plotinus this “way” is not—as it sometimes becomes in mediæval writers—a rigid series of mutually exclusive psychological states, separated by water-tight bulkheads. It is rather a diagram by which he seeks to describe one undivided movement of life; a prolonged effort and adventure, which has for its object a deeper and deeper penetration into Reality, the achievement of a true scale of
