Smashing the Mirror of Yamato: Sakaguchi Ango, Decadence & a Postmetaphysical Buddhist Critique of Culture

This article focuses on several key philosophical themes in the criticism of Sakaguchi Ango (1906–1955), one of postwar Japan’s most influential and controversial writers. Associated with the underground Kasutori culture as well as the Burai-ha of Tamura Taijirō (1911–1983), Oda Sakunosuke (1913–1947) and Dazai Osamu (1909–1948), Ango gained fame for two provocative essays on the theme of daraku or “decadence”—Darakuron and Zoku darakuron—pubished in 1946, in the wake of Japan’s traumatic defeat and the beginnings of the Allied Occupation. Less well-known is the fact that Ango spent his student years studying classical Buddhist texts in Sanskrit, Pali and Tibetan, and that he at at one time aspired to the priesthood. The article analyses the concept of daraku in the two essays noted above, particularly as it relates to Ango’s vision of a refashioned morality based on an interpretation of human subjectivity vis-à-vis the themes of illusion and disillusion. It argues that, despite the radical and modernist flavor of Ango’s essays, his “decadence” is best understood in terms of Mahāyāna and Zen Buddhist concepts. Moreover, when the two essays on decadence are read in tandem with Ango’s wartime essay on Japanese culture (Nihon bunka shikan, 1942), they form the foundation for a “postmetaphysical Buddhist critique of culture,” one that is pragmatic, humanistic, and non-reductively physicalist.

Slow Strain Rate Testing and Stress Corrosion Cracking of Ultra-Fine Grained and Conventional Al-Mg Alloy

Stress corrosion cracking susceptibility was investigated for an ultra-fine grained (UFG) AI-7.5Mg alloy and a conventional 5083 H111 alloy in natural seawater using slow strain rate testing (SSRT) at very slow strain rates between 1E(-5) s(-1), 1E(-6) s(-1) and 1E(-7) s(-1). The UFG Al-7.5Mg alloy was produced by cryomilling, while the 5083 H111 alloy is considered as a wrought manufactured product. The response of tensile properties to strain rate was analyzed and compared. Negative strain rate sensitivity was observed for both materials in terms of the elongation to failure. However, the UFG alloy displayed strain rate sensitivity in relation to strength while the conventional alloy was relatively strain rate insensitive. The mechanical behavior of the conventional 5083 alloy was attributed to dynamic strain aging (DSA) and delayed pit propagation while the performance of the UFG alloy was related to a diffusion-mediated stress relaxation mechanism that successfully delayed crack initiation events, counteracted by exfoliation and pitting which enhanced crack initiation.
