There is age-related yellowing. There are traces of paper having been peeled off from a used bookstore. There are marks from being tied with a string near the center. Other than that, I believe the condition is good. I would appreciate it if you could consider this, understanding that it is a used book. I have taken photos to show the condition of the book as much as possible, so please take a look. The Idea of the Holy by Rudolf Otto, Translated by Eiji Hisamatsu. Save Image. The overwhelming experience of the irrational "holy" = numinous, which lies at the heart of developed religion. A foundational classic of religious studies representing the 20th century. At the heart of rationally developed religion lies something irrational—the overwhelming experience of the "holy" through emotion and intuition. Otto (1869-1937) named its essence "numinous" and developed a phenomenological and religious-philosophical examination. A foundational classic of religious studies representing the 20th century, which has had a great influence not only on Christian theology but also on philosophy and comparative religious studies.
