1018. At the left side of the head or skull are those who during their bodily life had despised or harassed goodness, or everything relating to affection; at the right side, those who had done the same to truths, which are the deeper knowledge of what is good and true. As a result of falsities born from the thinking process and resulting conclusions, the brain is said to harden. Someone told me this and said that he now and then saw hardenings of this kind in me due to some slight cause, in other locations as well [as the brain]. I also experienced the pain resulting from their being softened, which varied from dull to sharp, depending on the kind of falsity that caused them. 1748, 26 February.
