Plotinus, an Alexandrian philosopher of the Neo-Platonic school, born at Lycopolis, in Egypt; he taught philosophy at Rome, a system in opposition to the reigning scepticism of the time, and which based itself on the intuitions of the soul elevated into a state of mystical union with God, who in His single unity sums up all and whence all emanates, all being regarded as an emanation from Him (207-270).
