In The Philosopher and the Art of Music, Julius Portnoy presents a unique study that explores the profound relationship between philosophy and the development of music through the ages. The author discusses the influence of philosophical opinions on the course of music, and shows how philosophers did not limit their interest to the philosophy of music only, but rather studied this art in terms of its nature and influence, which made their opinions a great influence on its development. The roots of aesthetic thinking in music go back to the Greek philosopher Plato, who considered music a powerful force that could be exploited for good or evil, with its benefit or harm extending to the entire society. The book highlights how this philosophical vision influenced the attitude of philosophers towards music throughout the ages, and how radical developments in musical art in the early nineteenth century led to it declaring its autonomy, taking a more abstract form. This book combines philosophical analysis with historical study, making it an important reference for anyone interested in understanding the relationship between philosophy and music.

جوليوس بورتنوي هو فيلسوف وموسيقي أمريكي وُلد عام 1911. شغل منصب أستاذ الفلسفة في كلية بروكلين بنيويورك، وارتبطت أعماله ارتباطًا وثيقًا بالموسيقى. سعى بورتنوي إلى الربط بين الفلسفة والموسيقى، حيث قام بصياغة أفكاره في كتابين بارزين، هما "الفيلسوف وفن الموسيقى" و"الموسيقى في حياة المرء"، ليعكس من خلالهما تأثير الفلسفة على تطور الموسيقى عبر العصور.
