One of Dietrich von Hildebrand’s most unique contributions to philosophy, his discussion of the Heart is meant as a definitive rehabilitation of the affective sphere which has been neglected for so long by innumerable generations of philosophers. He approaches the subject matter in his typical negative philosophical approach of spending a handful of chapters on dispelling any false notion of affectivity or simply the various ways the affective sphere is absent such as pure passion and heartlessness. The real focal point of his discussion, however, comes in the last two sections which takes the more philosophical nature of the first section and applies it to the Sacred Heart of Christ. By elucidating the incomparable tenderness, charity, and gentleness of Christ’s Heart as a central theme in the Passion and the broader Christian theological conversation, he aims to cement the Heart as something even Christ took seriously above all. My one gripe with the section is that, at times, Hildebrand doesn’t make clear connections between the two sections, leaving them feeling a bit disjointed. It is reconciled a bit in the final section, The Human Heart Transformed, but the two distinct conversations on the philosophical nature of the Heart and the theological significance of the Sacred Heart are never wrapped up in the same succinct way that he does in Ethics.
That being said, the book itself is still wonderful and one of the central texts of Hildebrand’s canon that helps elucidate the rest of his vast corpus of writings! I highly recommend it, especially for those who are new to DvH!
