Alogon (Greek) Used by Pythagoras and Plato for the irrational soul in man, divided into the thymichon and epithymichon; the rational soul was called logos. (BCW 7:229)
Aistheton (Greek) Sensible, perceived by the senses; used by Plato in contrast with noeton (intelligible) to indicate the visible aspect of the primeval cause of the manifested world. (FSO 194)
Energeia (Greek) Act, actual existence; used by Aristotle in contrast to dynamis (potency, power); these correspond to Plato's aistheton (sensible) and noeton (intelligible) (BCW 12:553; FSO 194).
Dunamis (Greek) Potency; used by Aristotle in contrast to energeia (act), for the invisible aspect of the universe as opposed to the visible or manifest; equivalent to Plato's noeton (intelligible) and aistheton (sensible) {FSO 194}.

The Puranic account speaks of the island as still existing.
