Chapter 4 concerns itself largely with the mysterious question of Gatsby's past. Gatsby's description of his background to Nick is a daunting puzzle, though he rattle off a seemingly far-fetched account of his grand upbringing and heroic exploits. The luncheon with Wolfshiem gives Nick his first unpleasant impression that Gatsby's fortune may not have been obtained honestly. Now that Gatsby is a full-fledged character in the novel, the bizarre inner conflict that enables Nick to feel such contradictory admiration and repulsion for him becomes fully apparent—whereas Gatsby the lovesick soldier is an attractive figure, representative of hope and authenticity, Gatsby the crooked businessman, representative of greed and moral corruption, is not. Chapter 4 illuminates a matter of great personal meaning for Gatsby: the object of hope.
