Abstract
The term ἀλλοίωσις appears in Plato's Republic, 381, as a verb, when Socrates speaks about the fact that the brave and wise soul is the least disturbed and changed by external influences. This term as a noun, in its Latin rendering, alienatio, occurs in St. Augustine, as we shall see presently. Plotinus' description of the relationship between contemplation and the soul's loss of knowledge of herself, is of decisive importance in this context. When the soul is immersed in pure contemplation it loses itself, or if we may freely employ this term, achieves the stage of alienation. Plotinus uses the term ἀλλοίωσις, as well as a term connoting the loss of all concepts and forms by the contemplating mind. It is from this rendering of the term alienation and the description contained in it, i.e., the soul's immersion of itself and the concurrent achievement of the immersion in the divine that St. Augustine uses the expression "alienatio mentis a sensibus corporis."
