在思想史研究中，如何实现“思想性”和“历史性”的有机结合一直是思想史研究界着力思考的问题，这一问题也关联着思想史的身份是否具有合法性。通过对思想史研究身份认同合法性危机的理论考察，并借助思想史研究的一些实例，对思想家文本展开精细解析，由此，今后的思想史研究或将能够实现“思想性”与“历史性”两者融贯结合，创造出鲜明的研究范式，化解目前思想史研究的“身份认同”危机，进而确立起思想史这一“身份”的合法性地位。

How to achieve the organic integration of “thoughtfulness” and “historicalness” has always been a focus in the research of intellectual history. This issue is also related to whether the identity of intellectual history is legitimate. Through theoretical study of the legitimacy crisis of the identity of intellectual history research, and with the help of some examples of intellectual history research, this paper analyzes the texts of thinkers in detail. In such a way, it would be possible to achieve a fusion of “thoughtfulness” and “historicalness” in future intellectual history research, create a distinct research paradigm, resolve the “identity crisis” of current intellectual history research, and finally establish the legitimacy of the “identity” of intellectual history.
