NeopythagoreanismNeopythagoreanism (or neo-Pythagoreanism) was a school of Hellenistic and Roman philosophy which revived Pythagorean doctrines. Neopythagoreanism was influenced by middle Platonism and in turn influenced Neoplatonism. It originated in the 1st century BC and flourished during the 1st and 2nd centuries AD. The Encyclopædia Britannica Eleventh Edition describes Neopythagoreanism as "a link in the chain between the old and the new" within Hellenistic philosophy.
Anima mundiThe anima mundi (Greek: ψυχὴ κόσμου, psychè kósmou) or world soul is, according to several systems of thought, an intrinsic connection between all living beings, which relates to the world in much the same way as the soul is connected to the human body. Although the concept of the anima mundi originated in classical antiquity, similar ideas can be found in the thoughts of later European philosophers such as those of Baruch Spinoza, Gottfried Leibniz, Immanuel Kant, Friedrich Schelling, and Georg W.F.
Dualism in cosmologyDualism in cosmology or dualistic cosmology is the moral or spiritual belief that two fundamental concepts exist, which often oppose each other. It is an umbrella term that covers a diversity of views from various religions, including both traditional religions and scriptural religions. Moral dualism is the belief of the great complement of, or conflict between, the benevolent and the malevolent. It simply implies that there are two moral opposites at work, independent of any interpretation of what might be "moral" and independent of how these may be represented.
Western philosophyWestern philosophy encompasses the philosophical thought and work of the Western world. Historically, the term refers to the philosophical thinking of Western culture, beginning with the ancient Greek philosophy of the pre-Socratics. The word philosophy itself originated from the Ancient Greek (φιλοσοφία), literally, "the love of wisdom" φιλεῖν , "to love" and σοφία sophía, "wisdom").
SyrianusSyrianus (Συριανός, Syrianos; died c. 437 A.D.) was a Greek Neoplatonist philosopher, and head of Plato's Academy in Athens, succeeding his teacher Plutarch of Athens in 431/432 A.D. He is important as the teacher of Proclus, and, like Plutarch and Proclus, as a commentator on Plato and Aristotle. His best-known extant work is a commentary on the Metaphysics of Aristotle. He is said to have written also on the De Caelo and the De Interpretatione of Aristotle and on Plato's Timaeus.
Neoplatonism and ChristianityNeoplatonism was a major influence on Christian theology throughout Late Antiquity and the Middle Ages in the West. This was due to St. Augustine of Hippo, who was influenced by the early neoplatonists Plotinus and Porphyry, as well as the works of the Christian writer Pseudo-Dionysius the Areopagite, who was influenced by later neoplatonists, such as Proclus and Damascius. Early Christians including Origen, Gregory of Nyssa, and Augustine were influenced by Neoplatonism, but none accepted it uncritically and they rejected absolute monism and its emanationists' views.
DamasciusDamascius (dəˈmæʃəs; Δαμάσκιος, 462 – after 538), known as "the last of the Athenian Neoplatonists," was the last scholarch of the neoplatonic Athenian school. He was one of the neoplatonic philosophers who left Athens after laws confirmed by emperor Justinian I forced the closure of the Athenian school in c. 529 AD. After he left Athens, he may have sought refuge in the court of the Persian King Chrosroes, before being allowed back into the Byzantine Empire.
Middle PlatonismMiddle Platonism is the modern name given to a stage in the development of Platonic philosophy, lasting from about 90 BC – when Antiochus of Ascalon rejected the scepticism of the new Academy – until the development of neoplatonism under Plotinus in the 3rd century. Middle Platonism absorbed many doctrines from the rival Peripatetic and Stoic schools. The pre-eminent philosopher in this period, Plutarch (c. 45–120), defended the freedom of the will and the immortality of the soul.
Christian philosophyChristian philosophy includes all philosophy carried out by Christians, or in relation to the religion of Christianity. Christian philosophy emerged with the aim of reconciling science and faith, starting from natural rational explanations with the help of Christian revelation. Several thinkers such as Origen of Alexandria and Augustine believed that there was a harmonious relationship between science and faith, others such as Tertullian claimed that there was contradiction and others tried to differentiate them.
EmanationismEmanationism is an idea in the cosmology or cosmogony of certain religious or philosophical systems. Emanation, from the Latin emanare meaning "to flow from" or "to pour forth or out of", is the mode by which all things are derived from the first reality, or principle. All things are derived from the first reality or perfect God by steps of degradation to lesser degrees of the first reality or God, and at every step the emanating beings are less pure, less perfect, less divine.
