What is human character? How does it develop? Is it innate? How do others perceive me? Can I change? Mathias Jung draws a wide arc from the character types of antiquity to the definitions of modern psychology. Hippocrates, Galen, Sigmund Freud, C. G. Jung, Fritz Riemann, and many others are explained with their different perspectives. Through a variety of cultural and philosophical reflections, literary quotes, and illustrative cases from psychotherapeutic practice, the author succeeds in creating an exciting panorama of our innermost selves. Along the way, we encounter questions that significantly influence our way of life.
