William Golding had a motto, "Nothing Twice," a motto that seems, indeed to fit his life as he rose from obscurity to fame with the publication of Lord of the Flies in 1954. Then, he was lost in the public's eye again until the end of the 1970s. From 1979 to 1982 were suddenly profitable to him, and in 1983, he received the Nobel Prize for Literature.
Perhaps, then, you could create subheadings derived from the motto of Golding. With an inquiring mind and the courage to try different approaches to his craft, Golding's writing was at times popular; other times it was not. Thus, it would seem that the periods of Golding's life mark different periods of thought for Golding. Researching these different periods may reveal for you his mode of thinking at the time. For instance, his father, who had a profound influence upon him, believed strongly in science and rational thought, but Golding's switching from Science to English as a major in college indicates his disillusion with the rationalism of his father. In Lord of the Flies, for instance, it is the intuitive Simon, not the rational Piggy, who truly recognizes the "beast" as the innate evil in man.
In addition, Golding's experiences in the British Navy had a profound influence upon his thinking. He himself described his experiences as having "one's nose rubbed in the human condition." This experience, of course, along with his interest in philosophy, is what gave rise to his most famous novel.
Are you looking for talking points about Golding or about his work? If you are looking for talking points about Golding, perhaps you could discuss how his Naval career might have influenced his writing, especially in Lord of the Flies. You remember that the novel is set during wartime, and its theme of the evil that lies within each one of us, an evil that at times causes man to wage war against his fellow man, was certainly a result of the horror of war that he witnessed. You may also remember that it is a Naval officer that comes onto the island at the end of the novel to rescue the boys.
Another point you could discuss is how his experience as a teacher gave him insights into the nature of children.
