本文以清代学术笔记中的《孟子》考证为研究对象，主要论述了以下四个方面的内容： 一，清人笔记中对孟子其人与《孟子》其书的研究情况。清人对孟子的生卒年进行了深入的考证，形成了多种说法，其中以生于烈王四年、卒于赧王二十六年说为主，此说应该与孟子真实的生卒情况相差不远。清人纂集了文献中出现的孟子表字，但均出于魏晋之后，其说不足为信。关于孟子的出仕行迹，清人经过考证，首先确定了《史记》所载梁惠王卒于三十六年为误，接着证明了孟子曾两度仕齐，结论可信。关于《孟子》成书，清人搜集了诸多观点，经过考辨，其中《史记》所载孟子与弟子共同创作的说法最为合理。而《孟子外书》，汉代之后即已亡佚，明万历年间所出为伪作，但伪书之中有不伪的内容，典籍所引未见于今本《孟子》的语句，可能是《孟子外书》逸句。 二，清人笔记中对《孟子》所载人物与史事的研究情况。关于孟子弟子，赵注、孙疏、朱注意见一致的为十三人。对于意见相左的人物，清人多赞成朱子之说，认为季孙、子叔并非孟子门人。全祖望认为告子非孟子弟子，观点亦可取。其他考证观点如琴张非子张、为琴牢，《古纪》《世本》所载考公、元公即滕定公、滕文公，曾西非曾子之孙、为曾子之子，费惠公即春秋时期鲁国季氏之后等，亦均可信。所载史事方面，清人就梁惠王“丧地于秦七百里”一语进行辨证，梳理出秦魏之间战败割地的一系列史事。其他如“舜为不顺于父母”并非事实，“象封有庳”应在国都附近等说，亦足参考。 三，清人笔记中对《孟子》经本校勘、文句、字词考证的研究情况。清代学者在《孟子》文本的校勘、文句的句读和理解、字词的训诂等方面做出了许多有价值的考证。例如《孟子》“摩顶放踵”《文选》注引作“摩顶致于踵”，可知唐本《孟子》与今本《孟子》不同；“必有事焉而勿正心”，以“正心”为“忘”字之讹，可备一说。“智足以知圣人，污不至阿其所好”，明确指出“污”字属下读，结论正确。字词考证方面，把“如就见”之“如”解为“宜”，把“若挞之于市朝”的“市朝”理解为连类而及，均为确解。 四，清代学术笔记中《孟子》考证的价值与不足。清人《孟子》考证往往能加深对前代注释的理解，还能针对文本提出新观点、阐发新理论。但是，清人笔记的缺陷也比较突出，主要表现在考证内容的重复和论证过程缺乏有效性两个方面。
