I love this quote from the foreword:
“Most of us are searching-consciously or unconsciously- for a degree of internal balance and harmony between ourselves and the outside world, and if we happen to become aware-like Stravinsky- of a volcano within us, we will compensate by urging restraint. By that same token, someone who bore a glacier within them might urge passionate abandon. The danger is, as Bergman points out, that a glacial personality in need of passionate abandon may read Stravinsky and apply restraint instead.”
