" The fusion of areas of consciousness which for us are more or less clearly defined leads, as it were, to a perpetual game of hide-and-seek with ourselves and to a confusion of ego positions. Emotional instability, ambivalent pleasure-pain reactions, the interchangeability of inside and outside, of individual and group—all these result in an insecurity for the ego which is intensified by the powerfully emotional and affective “vectors” of the unconscious. "
