The great chain of being

The great chain of being names Plotinus’s ordered account of reality and the spiritual journey back toward its source. Its movement downward, from the One through successive levels to matter, is matched by an ascent through intellectual and spiritual contemplation. The book treats this scheme as a major influence on Christian mysticism, while showing how later accounts of spiritual life also locate divine presence within embodied human relationships and responses to injustice.

The descending order of reality

Plotinus, a Greek philosopher who eventually taught in Rome, held that physical things change and deteriorate, whereas the ideas of things are eternal. His system begins with the One, also described as the Idea of the Good or God. Its nature overflows, or emanates, into lesser realms: first the Nous, Plato’s realm of ideas; then the World Soul, associated with intelligence; and finally matter, the least real level. Matter is not simply another item in the hierarchy: its pull can draw human beings away from the One.

This ordered descent makes the chain both a picture of reality and an account of spiritual difficulty. Human beings long for what is eternal and unchanging, but live in physical bodies and remain entangled in the world of sense. The chain therefore gives a structure to the gap between the source they seek and the material conditions in which they find themselves.

The ascent toward the One

The return journey reverses the downward movement. Through intellectual and spiritual contemplation, a person becomes less dependent on sensory experience and turns toward the intelligible world. The book describes this as a rising through the chain, sometimes understood as the mind’s journey to God or as mystical union with the One. Ascent is thus not a movement through physical space but a reorientation of attention and understanding toward what Plotinus considered ultimate reality.

The structure holds a tension between longing for transcendence and life in matter. Matter is the lowest level in Plotinus’s hierarchy, yet it is also where human beings are situated and from which they must begin their return. The chain makes spiritual life intelligible as both a fall away from unity and an effort to rise toward it.

Plotinus and Christian mysticism

Plotinus was not a Christian, but the book identifies his philosophy as a major influence on the development of Christian mysticism. He wrote nothing until about age fifty, when he began setting down the lectures he had given at his school. These treatises became the Enneads, a work described as a major achievement of both mystical and philosophical literature. His student Porphyry reported that he was present for four of Plotinus’s mystical experiences over six years.

The chain helps explain how a philosophical account of levels of reality could become a spiritual vocabulary: the movement from the sensory toward the intelligible offers a way to describe contemplation and union with the divine. Its influence does not make Plotinus a Christian; rather, the book distinguishes his own non-Christian teaching from the later Christian traditions shaped by it.

Embodied life and spiritual presence

The book’s modern examples complicate any simple equation between spiritual ascent and withdrawal from material life. Howard Thurman’s account of growing up amid racial segregation includes his grandmother, a former slave who inspired his faith. Because she could not read, he read the Bible to her; she refused to hear passages by Paul because he had instructed slaves to obey their masters. On a 1935 visit to Sri Lanka, a college principal challenged Thurman over Christianity’s association with slavery and racial oppression. Thurman distinguished Christianity from the religion of Jesus and argued that the spirit of Jesus could mean freedom, liberty, and justice. His later conversation with an Indian scholar moved beyond their initial religious defensiveness toward an experience of spiritual unity that, as Thurman described it, did not erase their individuality.

Simone Weil’s factory journal and Dorothy Day’s work with poor people offer different points of contrast with a hierarchy that places matter at the lowest level. Weil took a factory job because she wanted to experience the worker’s lot. Broken machines cost her production time, and repeated failure to meet the quota for full pay formed part of her account of how factory labor could wear down a worker’s self-respect. Day, by contrast, understood poor people as a primary revelation of God’s presence. Through the Catholic Worker, she and Peter Maurin addressed unemployment, labor, racism, and other social problems; their hospitality houses offered food and shelter. For Day, serving a difficult guest was not a distraction from divine life: the guest was to be received as Christ. Together, these episodes place the chain’s language of rising beyond dependence on matter beside a modern mystical emphasis on recognizing spiritual significance within material hardship and practical care.
