What is the effect of gatsby reaching through the dark setting toward the light

Answer 1

Gatsby's initial longing for the green light is because of Daisy. The green light, in a sense, symbolizes his past (mainly the love he cannot reach) and his faith. The effect of him gazing out at the green light (located at the end of Daisy's dock) informs us that he is 1.) searching for something (presumably Daisy) which he cannot obtain yet and 2.) is yearning for a past time which suited him.
