《幽明录》是刘义庆及其麾下门人所作的一部志怪小说集。其记载的内容丰富，不仅反映了晋宋之际的宗教信仰状况，也折射了当时的社会现实。与魏晋南北朝其他志怪小说相较，《幽明录》的独特性在其“文笔优美”和“强烈的现实感”。对这样一本具有特殊性的志怪小说，本文拟从以下几个方面进行探究。一是就《幽明录》相关文献问题进行探讨。首先，对《幽明录》版本进行梳理。其次，探究《幽明录》成书时间与写作原因：从文本出发，明确《幽明录》的成书时间。以此为线索对刘义庆写作《幽明录》的原因进行分析，提出刘义庆及其门人写作《幽明录》不仅有宗教信仰的原因，也出于对宋文帝刘义隆的迎合。此外，《幽明录》等书成于元嘉十七年后，刘义庆出镇南兖州之时，对刘义庆文学集团活动时间进行补充。二是分析史书对志怪的影响。志怪小说在魏晋南北朝时期被归入史部，史书传统对其写作影响巨大。故本文将以《幽明录》为核心，从史书意识对志怪的影响及史部模式化的写作对志怪内容的影响两方面进行讨论。三是志怪蕴含着丰富的时代思潮，对宗教信仰与民俗文化有着直接的展示。魏晋南北朝时，重“情”思潮的兴起影响了人们的思想，也影响到了人们对鬼神形象的想象和塑造。此时，发展出了看似写“鬼”实则写人的“鬼话”。“鬼”形象的变化在志怪中可以看到明显轨迹。故对这一过程进行梳理，借以探究时代思潮对“鬼”形象的影响，并具体探究《幽明录》在“鬼”“人情化”这一过程中的贡献。四是志怪传说在当时常与传教活动相联系，佛、道和以“巫”为代表的民间信仰都曾因各种原因编造神异传闻。故将对《幽明录》中反映的宗教色彩进行辨析，并就具体条目分析当时三种信仰的融合与斗争在志怪小说中的反映，从中探究晋宋时期的社会信仰状况。五是对《幽明录》的新变进行分析，指出其独特性所在。《幽明录》的文学成就与其强烈的现实感常为研究者称道。本文将就《幽明录》文学性增强的原因做出分析，借以探讨其文人化特征。《幽明录》对与刘义庆有交集的人多有记载，这种对“时事”的记载为虚幻的鬼神之说增添了强烈的现实感，故本文将对这一特点进行分析，并探讨这一现象背后的原因及其对后世志怪小说的影响。
