The best of Bunin's prose ("The Gentleman from San Francisco", "Loopy Ears" and notably, "Brothers", based on Ceylon's religious myth) had a strong philosophical streak to it. In terms of ethics Bunin was under the strong influence of Socrates (as related by Xenophon and Plato), he argued that it was the Greek classic who first expounded many things that were later found in Hindu and Jewish sacred books. Bunin was particularly impressed with Socrates's ideas on the intrinsic value of human individuality, it being a "kind of focus for higher forces" (quoted from Bunin's short story "Back to Rome"). As a purveyor of Socratic ideals, Bunin followed Leo Tolstoy; the latter's observation about beauty being "the crown of virtue" was Bunin's idea too. Critics found deep philosophical motives, and deep undercurrents in "Mitya's Love" and "The Life of Arseniev", two pieces in which "Bunin came closest to a deep metaphysical understanding of the human being's tragic essence." Konstantin Paustovsky called "The Life of Arseniev" "one of the most outstanding phenomena of world literature."
