It is true that "The Tale of Genji" was influenced by the Confucian philosophy and Buddhism, but those interpretations were mainly made for the enlightenment of people at that time and it's hard to say they were generated from the story itself; thus they disappeared with the emergence of the 'Mono no Aware' theory (to be mentioned later).
『源氏物語』自体の中に儒教や仏教の思想が影響していることは事実としても、当時の解釈はそれらを教化の手段として用いるためという傾向が強く、物語そのものから出た解釈とは言い難いこともあって、後述の「もののあはれ」論の登場以後は衰えることになった。
