    2000年,老舍先生的儿子、中国现代文学馆副馆长舒乙向外界披露了“1968年诺贝尔文学奖几乎被老舍得到”的内幕。舒乙透露,在入围者到了最后5名时还有老舍,最终,秘密投票结果的第一名就是老舍。那年,瑞典方面通过调查得知老舍已经去世,于是日本的川端康成获奖。1987、1988年诺贝尔文学奖终审名单之中,沈从文均入选,而且沈从文是1988年中最有机会获奖的候选人。诺贝尔文学奖终身评委马悦然曾透露,当时学院中有强大力量支持沈从文的候选人资格。但可惜的是,沈从文于1988年5月10日去世,因此与诺贝尔文学奖失之交臂。疑难突破《首届诺贝尔奖颁发》特别说明资金管理权和评奖权的分离,有什么用意?资金管理权和评奖权的分离能够有效保证诺贝尔奖评奖的公正性。公正性是权威性的基础,诺贝尔奖(特别是它的科技类奖项和文学奖)一百多年以来形成的权威性,与这一分离制度关系密切。就当时而言,诺贝尔奖只是首次颁发,特别需要强调其权威性。
