“On the Character and Spirituality of Architecture” (Shuo jianzhu pinge jingshen zhi suozai), published by Liang Sicheng in the Social Education Quarterly in June 1943, is not included in his complete works and is thus a forgotten article. Through investigating his writing background and analyzing his objective and main argument， the author believes that Liang’s article is the fifirst comprehensive expression of his aesthetic view on architecture.

Liang’s article was written when China began to anticipate success in the Sino-Japanese War, and was instructive to both construction and reconstruction during and after the war．
