Alec is referring to the biblical story of the fall of man, in which Eve was tempted to eat the fruit of the tree of knowledge in the Garden of Eden.

He goes on to quote John Milton's  Paradise Lost, an epic narrative poem of the creation story written in the 17th century. It gives prominence to Lucifer, the brightest of angels, who is reputed to have been cast into hell for his pride; in his new guise as Satan, Lucifer set about plotting the downfall of man.
