I’m listening to Sonny Rollins’ Blue 7. Choosing a next word, like deciding music, is a significant event entailing parallel yet soon defunct experiences unmeasured but hypothesized in a quantum construct. 
Choosing words or choosing most anything — an extraction process merges quanta, happenstance survivors plucked from a number of now-dead parallel event objects or topics. “When a word is selected as a ‘vivid detail,’” Wm. Empson insists, “a reader may suspect alternative reasons why it[’s] selected.” You’d think a given detail had been spinning either as two or many more meanings finally resolved (finished up) as confusion collapses, and one number or topical mood pops up and out, anecdotally at random. The rest are put to rest by now.
