"The growth of the soul may be compared to the growth of a plant. In both cases, no new properties are imparted by the operation of external causes, but only the inward tendencies are called into action and clothed with strength."

How is it to be explained that something inside me revolts against the playing of obvious moves? Perhaps we may perceive the underlying reason in the fact that I derive satisfaction from seeking to reveal the concealed meaning of a position by means of maneuvering play and therefore I do not wish to see this satisfaction curtailed by a banal, more or less fortuitous decision. Naturally, this phenomenon is played out beneath the threshold of consciousness. The waking consciousness will, of course, in each individual case, give preference to the more rapid means of deciding the game.
