Neoplatonism refers to the philosophical school of thought that emerged in the third century, which synthesized the teachings of Plato with those of other ancient philosophers. This term has several synonyms, including Neoplatonic philosophy, Platonic mysticism, Platonic spiritualism, Platonic theology, and Plotinism. The essence of Neoplatonism lies in its idea of the Absolute or the One, which is the ultimate reality transcending everything. It advocates for contemplative practices, mysticism, and the purification of the soul to achieve union with this divine reality. Neoplatonism has influenced several religious and philosophical traditions, and its impact can be seen even today in the areas of metaphysics, ethics, and aesthetics.
