7074. Some of the spirits of the earth Mercury were sent by others to me in order to hear what was going on with me; to whom one of the spirits of our earth said that they might tell their companions not to speak anything but the truth, and not in their usual way to present to those questioning them things opposite; for if anyone of the spirits of our earth were to do so, he would be punished. But the company from which those spirits had been sent out, which was at a distance, then answered that if they were to be punished on that account, all would be punished, because, from constant use, they cannot do otherwise. They said that when they speak with the men of their own earth, they act in the same way, and this with no intention to deceive them, but in order to inspire a longing for knowledge; for when they present things opposite, and in a certain way hide the real things, the desire of knowing is excited, and in this way the memory is enriched by the study devoted to the exploration of the things in question.
