Carl Gustav Jung(1875-1961) was a Swiss psychiatrist, an influential thinker and the founder of analytical psychology (also known as Jungian psychology). Jung's radical approach to psychology has been influential in the field of depth psychology and in counter-cultural movements across the globe. Jung is considered as the first modern psychologist to state that the human psyche is "by nature religious" and to explore it in depth. His many major works include "Analytic Psychology: Its Theory and Practice," "Man and His Symbols," "Memories, Dreams, Reflections," "The Collected Works of Carl G. Jung," and "The Red Book."
