基于哲学史研究的元哲学深度自觉，冯契的"哲学史两种"实质上构成了《智慧》到"智慧说三篇"的中介。由此，形成了冯契思想鲜明的总体性品格：哲学与哲学史的辩证统一、哲学理论创造和哲学史传统总结的有机融合。它既与黑格尔有关，但是更直接的来源系发掘中国哲学固有的历史主义传统和唯物史观的结合，因而冯契在批评独断论、对规律的辩证理解和哲学史发展动力的知识社会学方案等方面超越了黑格尔。在广义认识论的视野中，哲学史就是认识史，辩证法则是认识史的"总计"。而贯穿冯契哲学史两种的根本原则是实践的唯物主义辩证法。作为辩证的综合型哲学的历史展开，《中国古代哲学的逻辑发展》以范畴史为内在结构，凸显了中国哲学的辩证思维传统；基于强烈的现实感，《中国近代哲学的革命进程》提示了传统观念创造性转化的现实性，更开启了哲学观念史研究的新空间。

Based on his keen meta-philosophical consciousness of the study of the history of philosophy, FENG Qi's study of the history of ancient Chinese philosophy and that of modern Chinese philosophy effectively constitutes a bridge between "Wisdom" and his "Doctrine of Wisdom". Hence, FENG's thought is characterized by the dialectical unity of philosophy and the history of philosophy and the organic integration of creating philosophical theory and summarizing the history of philosophy. Despite of its relation to Hegel, this is directly due to the combination of the intrinsic tradition of historicism in Chinese philosophy and historicist materialism. Therefore, FENG goes beyond Hegel in his achievement in criticizing dogmatism, dialectically understanding laws and examining research of the motivation of the history of philosophy from the perspective of intellectual sociology. From the perspective of the epistomology in a broad sense, the history of philosophy is a history of epistomology, and dialectics is the sum of the history of epistomology. The fundamental principle goes through FENG's study of the whole history of Chinese philosophy is practical materialistic dialectics. As historical unfolding of a dialectical and synthetical philosophy, The Logical Development of Ancient Chinese Philosophy takes the history of categories as its intrinsic structure and in this way demonstrates the dialectical tradition of thinking in Chinese philosophy. Based on a strong sense of reality, The Revolutionary Process of Modern Chinese Philosophy reveals the possibility of creative transformation of traditional ideas and opens up new space for the research of the history of philosophical ideas.
