298. The spirits who are with man, both those conjoined with heaven and those conjoined with hell, never flow into man from their own memory and its thought, for if they should flow in from their own thought, whatever belonged to them would seem to man to be his (see above n. 256). Nevertheless there flows into man through them out of heaven an affection belonging to the love of good and truth, and out of hell an affection belonging to the love of evil and falsity. Therefore as far as man's affection agrees with the affection that flows in, so far that affection is received by him in his thought, since man's interior thought is wholly in accord with his affection or love; but so far as man's affection does not agree with that affection it is not received. Evidently, then, since thought is not introduced into man through spirits, but only an affection for good and an affection for evil, man has choice, because he has freedom; and is thus able by his thought to receive good and reject evil, since he knows from the Word what is good and what is evil. Moreover, whatever he receives by thought from affection is appropriated to him; but whatever he does not receive by thought from affection is not appropriated to him. All this makes evident the nature of the influx of good out of heaven with man, and the nature of the influx of evil out of hell.
