E.g., Plato, Meno, 181A-D; Phaedo, 65A; 91E-92E; Timaeus, 44B; Cicero, Disp. Tuscul., I, 24; Proclus, Elements of Theology, Props. 177 (DDS 156 1) and 194 (DDS 168 30). Cf. S.T. I, 84, 3.

This doctrine has had a long history. Cf. the article, "Metempsycose," by Hedde in DTC, X, 1574 ff. Cicero, Disp. Tuscul., I, 16, says that Pherecydes of Syros was the first to say that souls are eternal. (On Pherecydes, see Freeman, Ancilla to Pre-Socratic Philosophers [Oxford, Basil Blackwell, 1948], 13-15). Among the Greeks this opinion was held by Pythagoras (Cf. Diogenes Laertes, VIII, 4-6), Empedocles (Frag. 112, 117, 127 in DL I:354-62), Plato (Gorgias, 525E-526; Phaedo, 92A, 114A; Republic, X, 614E-625A; Timaeus, 42b). On the Greeks, see also Gomperz, Greek Thinkers, (London: John Murray, 1901-5), I, 123 ff. Others who held this opinion were: the Gnostics, cf. Plotinus (Enneads, II, IX, 6); Plotinus (Enneads, I, i, 12); and Origen (Peri Archon, II, viii, 4 (PG 11:224); II, viii, 3 (PG 11:222).

This opinion was condemned in the sixth century at the Second Council of Braga (MA IX:775) and in Liber Justiniani imperatoris adversus Origen, which was approved by Pope Vigilius (MA IX:533).
