"I had believed that I was leaving nothing out of account, like a rigorous analyst; I had believed that I knew the state of my own heart. But our intelligence, however lucid, cannot perceive the elements that compose it and remain unsuspected so long as, from the volatile state in which they generally exist, a phenomenon capable of isolating them has not subjected them to the first stages of solidification. I had been mistaken in thinking that I could see clearly into my own heart. But this knowledge, which the shrewdest perceptions of the mind would not have given me, had now been brought to me, hard, glittering, strange, like a crystallised salt, by the abrupt reaction of pain."  Marcel Proust
