It is much the same as it is with the causes of events. Although we can see them rationally, we see them clearly only through their effects. The causes are in the effects and present themselves to view there. Only then is the mind sure about causes. I will discuss the effects of this correspondence later [378-384].

However, to prevent anyone from getting detoured into preconceived theoretical concepts of the soul in the discussion of these correspondences, some of the material presented in the preceding section may be reread: for example, 363-364, on love and wisdom, and therefore volition and discernment, constituting our essential life; 365, on our life occurring in its fundamental forms in our brains, and secondarily in our bodies; 366, on the quality of our life in its fundamental forms determining its quality throughout and in every part; 367, on the fact that through these fundamental forms there is life in the whole from every part and life in every part from the whole; 368, on the quality of the love determining the quality of the wisdom, and therefore the quality of the person.
