Don't want to belabor the subject, but I occasionally have feeling Salinger's children--at least Esme and Teddy--, are not, despite biological age, actually children--they are more mature, have more poise, knowledge, wisdom than "adults"--and at least in case of Esme, who has lost both parents in course of the war, "survivor skills" that X lacks. I see this involving less the ascription of "innocence" in Wordsworth's sense than something else specific to Salinger (but also other American postwar writers, including recently unjustly maligned Nabokov) who was seeking to come to grips with personal and collective trauma of the war. Similar case could be made for Holden. Seymour's attachment to Sybil is one measure of extent of this trauma. Denis Jonnes
