本文的行文思路，以“大同新村”为主体线索，通过“世/人”“国/家”“报恩/发愿”“净土/受记”四个方面，将作者的佛教大同主义思想或者说是理想展现出来。 《东方大同学案》作者刘仁航（1885—1938），是集诗人、佛学家、哲学家、养生学家、素食主义者、女权主义者等等于一身的民国学人。但他不仅仅是一个学人，同时还是一个社会活动家，是佛教大同主义的躬身实践者。该书由儒释道以及基督教等经典入手，结合国外乌托邦思想史，阐述自古以来的东方色彩浓厚的大同理想。 作者是站在佛教圆融无碍的立场上来谈的，也就是说，佛教的理论体系可以和与之不同的其他所有理论体系并存，不会偏执一端。但就本篇论文来说，由于是要理清佛教大同主义的脉络，所以就不得不将佛经文字所表达出来的明确含义确切化，将圆融无碍的佛法固定化。这确实是现代学术规范的要求，也是描述某某主义所必需的，还是本篇论文存在的理由，否则本人又何必在这里鹦鹉学舌呢！但烦请读者注意，本人所描述的佛教大同主义，只是佛法大海中的一滴而已。 The idea of my paper is, following “Datong village” as the main clue, through the “world” “human” “home” “country” “gratitude” “Pure-land” “Vyākaraṇa” those aspects, to show the author’s Datong ideology or ideal of Buddhist. Author Liu Renhang (1885—1938), is a poet, scholar, philosopher, health expert, vegetarian, feminist etc. He is not only as a scholar in the Republic of China, but also a social activist. The book talked about the classics of Confucianism, Buddhist, Dao, and Christianity, combined with the foreign history of utopian thoughts, elaborated Oriental Datong ideal since ancient times. The author is standing in the Buddhist harmonious position, that is to say, the theory of Buddhism can coexist with all other different theoretical systems. But in this paper, the Datong of Buddhist is to sort out, so we will have to clear the exact meaning of Buddhist text. This is not only the modern academic’s requirements, but also necessary to describe some ism, and the reason of why this paper exists, otherwise I should do a parrot here! But please note, my reader, Datong of Buddhist, is just a drop in the ocean of the Buddha dharma.
