Plotinos: Complete Works, v. 3 / In Chronological Order, Grouped in Four Periods

The essays examine how unity, multiplicity, and number relate in a Neoplatonic metaphysics, arguing that manifoldness represents distance from the One and risks degradation or evil when parts disperse from self-unity. They probe whether infinity can be numbered or subsist intelligibly, distinguishing determinate multiplicity in the intelligible realm from undetermined becoming in time, and describe how the infinite is conceived only by abstracting form, showing it to encompass apparent contraries such as movement and rest. Discussions also treat beauty, participation, and the conditions under which magnitude preserves or loses ontological identity.
