And if thus our recent studies of morbid mentalities have been able to throw a flood of light upon the mechanism and character of the healthy mind, a mind more difficult to analyze precisely because of the harmonious interaction of its forces, there is nothing very surprising if man, in the past, learnt to know his own fundamental nature better in and through periods of abnormal excitation than in those of normal balance. And the resultant doctrines in the case in question only required, and demand again and again, a careful pruning and harmonizing to show forth an extraordinary volume of abiding truth. The insuppressible difference between mind and matter, and the distinction between the fully recollected soul (intuitive reason), and explicit reasoning; the immeasurable superiority of mind over matter, and the superiority of that full reason over this “thin” reasoning; the certainty, involved in all our inevitable mental categories and assumptions and in all our motives for action, of this mind and intuition being more like the cause of all things than are those other inferior realities and activities; the indestructibleness of the postulates and standards of objective and infinite Beauty, Truth, Goodness, of our consciousness of being intrinsically bound to them, and of our inmost humanity and its relative greatness being measurable by just this our consciousness of this our obligation, and hence by the keenness of our sense of failure, and by our striving after purification and the realization of our immanental possibilities: all this remains deeply fruitful and true.
