More on essence:
"I think of what Doris Lessing wrote in The Four-Gated City: 'In any situation anywhere there is always a key fact, the essence. But it is usually every other fact, thousands of facts, that are seen, discussed, dealt with. The central fact is usually ignored, or not seen.' And a sentence of Yukio Mishima's in Spring Snow: 'To live in the midst of an era is to be oblivious to its style.'" - Michael Ventura, in We've Had a Hundred Years of Psychotherapy and the World's Getting Worse by James Hillman and Michael Ventura.
