| 1. Freud defines three stages of sexuality, the oral, the anal and the oedipal stage. An infant in its oral stage learns that there is an external world through pleasure and pain. Human nature is governed by the pleasure principle. When the infant is being breast fed he/she feels pleasure and when pulled away from the breast the baby feels pain. The pleasure principle is a way of seeking pleasure in order to avoid pain. We can’t be happy all the time because three things threaten us. First of all our own bodies can’t handle too much pleasure at once, eventually our bodies get older and death is inevitable. second, natural phenomenon’s get in our way, and third our relationships with others. We are emotionally dependent on others and when we take their words into consideration we become unhappy. Since we can’t be happy all the time we need to learn how to avoid pain. There are five ways we can avoid pain. We can become hedonistic and gain pleasure at all costs all the time. This way of avoiding pain isn’t really possible due to the fact that we wouldn’t be able to accomplish anything else in our lives. second way of avoiding pain is by voluntary isolation.

Heart of Darkness - Joseph Conrad |
| Joseph Conrad, in his long-short story, ³Heart of Darkness,² tells the tale of two mens¹ realization of the hidden, dark, evil side of themselves. Marlow, the ³second² narrator of the framed narrative, embarked upon a spiritual adventure on which he witnessed firsthand the wicked potential in everyone. On his journey into the dark, forbidden Congo, the ³heart of darkness,² so to speak, Marlow encountered Kurtz, a ³remarkable man² and ³universal genius,² who had made himself a god in the eyes of the natives over whom he had an imperceptible power. These two men were, in a sense, images of each other: Marlow was what Kurtz may have been, and Kurtz was what Marlow may have become. . Heart of darkness, joseph, conrad |

Jerome David Salinger The Catcher In The Rye |
|
As a novelist, J.D. Salinger belongs to a distinct group of American writers who began their literary careers during or immediately after the second World War, the so-called “young novelists” – James Baldwin, William Styron, etc.
The Ctcher in the Rye confirmed and sustained his reputation and gained him a position as one of the most important American writers of the young generation. The book is nevertheless a first-rate novel and one of the most convincing studies of adolescence ever to be written by an American. Salinger is widely seen as a keen students of children. In 1951 he published The Catcher in the Rye – a touching psychological study of adolescence, in which he views the American way of life through the eyes of a teen-age nonconformist, Holden Caulfield, a twentieth century rival of Twain’s Huck Finn. Holden is a person whose defining quality is his inability to behave according to the strict morals and social code of the day. Salinger’s sensitive and defiant school boy defies conventions and remains innocent about them. Holden images himself protecting a group of children happily playing in a rye field, from falling into a nearby precipice: “keep picturing these little kids, playing some game in this big field of rye....Thousands of little kids, and nobody around – nobody big, I mean except me. And I am standing on the edge of some crazy cliff. What I have to do? I have to catch everybody if they start to go over the cliff. I mean – if they are running and they don’t look where they are going. I have to come out from somewhere and catch them. That’s all I do all day. I’d just be the catcher in the rye and all.”............. . Holden, salinger, catcher, in, the, rye, novel |

Writings of J.D. Salinger |
| Many critics consider J.D. Salinger a very controversial writer, for the subject matters that he writes.. J.D. Salinger’s works were generally written during two time periods. The first time period was during World War II, and the second time period was during the 1960’s. Critics feel that the works during the 1960 time period were very inappropriate, because of the problems for which he wrote. The main characters were generally misfits of society. In most of his works, he has the protagonist of the story go on a quest for happiness. Salinger does not conform to the material happiness; the characters undergo a spiritual happiness. The characters generally start out as in bad conditions, through the end of his works they undergone changes that change them for the better. . J, d, salinger |
