conception of the nature of the universe that had a pervasive influence on Western thought, particularly through the ancient Greek Neoplatonists and derivative philosophies during the European Renaissance and the 17th and early 18th centuries. The term denotes three general features of the universe: plenitude, continuity, and gradation. The principle of plenitude states that the universe is "full," exhibiting the maximal diversity of kinds of existences; everything possible (i.e., not self-contradictory) is actual. The principle of continuity asserts that the universe is composed of an infinite series of forms, each of which shares with its neighbour at least one attribute. According to the principle of linear gradation, this series ranges in hierarchical order from the barest type of existence to the ens perfectissimum, or God.
