Lecture IX
Anyone who is alert to his surroundings will find that this inadequate, pseudo-thinking is very widespread. If with the help of super-sensible research we trace the path of such an individual backwards and come to the regions through which his soul passed between the last death and the last birth, when this illogical mentality was caused, the seer often finds that this type of human being, in his last life between death and rebirth, passed through the spiritual world in such a way that he encountered the spiritual Beings and forces while under the guidance of Ahriman; and that although those Beings would have bestowed upon him what he needed in life, they could not make it possible for him to develop the capacity for sound thinking. Ahriman was his leader and it was Ahriman who contrived that the gifts of the Beings of the higher Hierarchies could only be received by him in a form that would finally result in his thinking coming to a halt when confronting actual facts, and in his inability to make his thinking exhaustive and valid. A large proportion of those human beings—and their number is legion—who are incapable of genuine thinking today owe this to the fact that in their last life between death and rebirth they were obliged to submit to Ahriman's guidance; they had somehow prepared themselves for this in their last earthly life—that is to say, in the incarnation preceding the present one.
