The transcendent function is the core of Carl Jung's theory of psychological growth and the heart of what he called individuation, the process by which one is guided in a teleological way toward the person one is meant to be. This book thoroughly reviews the transcendent function, analyzing both the 1958 version of the seminal essay that bears its name and the original version written in 1916. It also provides a word-by-word comparison of the two, along with every reference Jung made to the transcendent function in his written works, his letters, and his public seminars.
