There are a variety of possible reasons behind these perceptions, some of which will be addressed here. After providing a short biography, this paper will address some of the background elements that might have influenced his theories, mention three of the theories themselves in terms of their contribution to psychology, note some objections leveled at Jung’s ideas, and conclude with my own personal thoughts on his theories.Carl Gustav Jung was born in 1875 on the Swiss shore of Lake Constance to Paul and Emilie Jung, a village pastor and the youngest daughter of a famous-but-eccentric theologian (Stevens, 2001, p. 2). Jung’s father died when he was still in school and, although his first career choice was that of a medical doctor, he was precluded from pursuing this career path due to the fact that he could not afford to do so. he opted instead, to go to work as an assistant at the Bergholzli asylum proximate to Zurich (Daniels, 2003, p. 24). He met and developed a friendship with Sigmund Freud, with whom he corresponded often until a series of philosophical and perceptive differences caused the break (Stevens, 2001, pp. 18-24). He married and had a family and, although seemingly happy with his wife Emma, nevertheless engaged in several well-documented affairs. After World War I, he spent much of his time traveling and writing much of the work we have today. He died in 1961.There are many aspects of Jung’s life and experiences that can be seen in his subsequent work. so much so that they lie far beyond the scope of this paper. There are a few, however, that should be mentioned to provide context for the theories and his contribution to society which follow.The first is the environment in which Jung developed. In speaking of the period of time between the 1870s and 1930s, one author notes that “the major disciplinary and theoretical forms of modern psychology and psychotherapy were established” (Shamdasani, 2003, p. 10).
