QUOTE : What apparently started as a loosening of semantic context, which allowed the patient to make a witty play with words about pyramids and 'extrapyramidal' disorders, completely lost its humorous character when the patient experienced the profound anxieties and cognitive impairments associated with a severe psychotic crisis. Experiencing the lack of precision of higher-order concepts, in this case clear distinction between pyramids in Egypt and pyramids in the brain, can thus be a curse and blessing at the same time: it allows us to detect the fundamental imprecision of language and the shaky metaphorical ground on which common concepts about ourselves and the world are based, and this experience can lead to a state of exhilaration about the fundamental nonsense of the world, the nonexistence of our assumed securities, and the shallowness of cherished beliefs, but it also confronts us with overwhelming complexity and threatening insecurity and throws us in deep anxious turmoil when confronted with the sheer chaos of being.
