42. It should also be known that there are three degrees of love and wisdom, and so three degrees of life; and the human mind is formed into three regions corresponding to these degrees. Life in the highest region is in its highest degree, in the second in a lesser degree, and in the last in the lowest degree. These regions are opened up successively as a person grows up. The last region, where life is in its lowest degree, is opened up from infancy to childhood, as different kinds of knowledge are acquired. The second degree, where life is in a greater degree, is opened up, from childhood to adolescence, as the result of thinking based on knowledge. The highest degree, where life is in its highest degree, is opened up from adolescence to early manhood and beyond; and this is brought about by grasping both moral and spiritual truths.
