Are human beings born with a moral character, or does our character form and change as we experience life? In The Will's Harmonic Motion, author Fadel Sabry sheds light on this age-old question. An extension of Arthur Schopenhauer's work, philosophy, and discussion, The Will's Harmonic Motion puts forth an extensive discussion of how moral character is obtained and on what basis. It provides an overview of Schopenhauer's treatment of metaphysics and introduces the concept of the will. It also explains the nature of morality and intelligible and empirical characters and investigates movements in nature, especially harmonic motion, and reviews the scientific laws that govern it. The study extends the concepts of moral characters and curves to animals, explains the mysterious qualities of creative power and healing power, explores the topic of pleasure, and addresses the mystery of existence. This study approaching metaphysical subjects scientifically, seeking to apply rational thinking to all topics considered, including morality, death, and religion. Bringing new ideas to philosophy, Sabry considers these themes and more in his search for the truth about moral character.
