This book is a revolution in philosophy. Based on Schopenhauer's philosophy, completed it, and took it to higher level.

Schopenhauer's concept of the will and morality form the basis for this book. Schopenhauer taught that our moral

character is inborn and unalterable, but provides no explanation being metaphysical.

This book proved without any doubt that our moral character is assigned to us according to a specific, unalterable, and

predictable system. It proved it scientifically and through daily observation of human behavior. It observed that moral

characters change and move as a sine curve, i.e., harmonic motion.

After establishing this groundbreaking theory of the Will's Harmonic Motion, Sabry extended it to cover and explain many

topics including animals, pleasure, physical and metaphysical actions, death, eternal justice, and salvation.
