> Sociologists will find most provocative the author's alternative to Erving Goffman's analysis of self-consciousness. Both are mystics in the sense that they investigate the conditions causing someone to lose self-consciousness. But Goffman is what I would call a pessimystic, for in Frame Analysis (1974:378ff) he examines how the self disappears in the "negative experience" that results when situational contradictions increase its stress; Csikszentmihalyi is an optimystic, for he ex-
amines how the self disappears in the "flow experience" that results when situational consonances decrease its stress

> The Anglophone universe becomes a linguistic afterlife in which Nabokov optimistically hopes to resurrect his Russian art, just as he “optimystically” (the pun belongs to Sebastian Knight’s “Dean Park”) expects that the otherworld preserves the spirits of his dead.
> Coauthors Taylor and Crain discuss the concept of "optimysticism," first intro- duced in Taylor's Messengers of Light. The phrase refers to the ability to see beyond the worst of situations to the mystery of goodness at the core of life.
> Optimysticism is the choice we make not only to experience the best of this world but also to see beyond this world into eternity, and in doing so, to live the mystery of the fullest here on earth.
