1890. THE CONTENTS The subject treated of in this chapter is the Lord's first rational, which was conceived by the influx of the internal man into the affection of memory-knowledges [scientiae] of the external. The internal man is "Abram;" the affection of memory-knowledges in the external is "Hagar the Egyptian handmaid;" the rational thence derived is "Ishmael." The nature of this rational is here described; and it is afterwards said (chapter 21) that it was expelled from the house, after the Lord's Divine rational, represented by Isaac, had been born.
