鄭樹森在〈遺忘的歷史，歷史的遺忘－－五、六十年代的香港文學〉一文與《香港新文學年表（一九五○－一九六九年）》一書中與黃繼持、盧瑋鑾的〈三人談〉中，自覺地提出他們整理史料的限制，嘗試理清歷史與遺忘的本質。本論文由鄭樹森附帶著無力感的「遺忘論述」出發，透過馬博良在《文藝新潮》停刊後數年離開香港，一度消失於文壇再於1976年復出，以及梁秉鈞1962年間的「馬朗發現事件」，探討「遺忘」與「反遺忘」的矛盾或複雜性；此外，「遺忘」這現象如何被意識到、被標示出，以至被論述到，而其附帶著無力感、哀懷、嘆喟，又如何呼應文學史的發展，以至參與了文學性的塑造。

This paper examines discourse of the forgotten by focusing on two issues of literary history, namely, Ronald Mar's leaving Hong Kong, his disappearance from the literary world a few years after the suspension of the periodical ＂New Tides of Literature and Arts＂, and his return to the literary world in 1976; and Leung Ping-kwan's ＂discovery of Ronald Mar＂ in 1962, in conjunction with the reflection on historical compilation of Hong Kong literature by William Tay. To extend the meaning of discourse on the forgotten, this paper also discusses how the issue on the forgotten had been realized, indicated and discussed in the history of Hong Kong literature, and how the sense of powerlessness, sorrow and regret has responded to the development of the literary history and participated in the shaping of the literariness.
