21世纪，技术及其发展正全面地渗透到人们生活的方方面面。在一些关键技术领域，技术的突破对人们的生活甚至人类本身产生了日益重要的影响。伴随着技术的这种发展，技术不断地重新定义人类关于“自我”及其他相关概念的深刻内涵，促使人们深入地反思自我、人作为人的本质属性、道德主体性地位、价值、身份及其所受到的影响和由此发生的变化等一系列问题。因此，“我是谁”这一哲学中关涉到人类自我认识的重要议题在当今技术时代中又被赋予了新的涵义。对于这一问题的探究无疑要将“技术”这一重要维度纳入进来，从而也促进了学术兴趣的增长和一个新的跨学科研究领域的出现。这个跨学科研究领域即是近年来兴起的“技术自我研究”（Technoself Study）领域。 “技术自我”这一概念作为技术自我研究领域的核心概念之一，将此前社会思潮中出现的反映人与技术/机器二者之间关系的诸多概念做了整体性统合。其关注的重点在于，采用了以互联网技术和人类增强技术为代表的技术之后，当前社会中的人类自身状态以及人与技术二者的关系都由此发生了哪些变化，以及这些变化引发的人类对如何认识自身、如何看待自身与技术的关系的再思考与探讨。 本论文聚焦技术自我研究中最为重要的主题——技术自我的身份认同问题。从时间和技术两个维度出发，对身份认同理论中心理连续性说明、身体性说明和叙事性理论的解释思路，以及技术哲学家斯蒂格勒等关于人与技术关系的论述进行重新考察、分析、提炼。指出既有理论存在认识论层面上的风险，无法很好地解释互联网技术中所涌现的在线身份、“化身”等新问题，也无法很好地回应人类增强技术对身体性作为身份认同强制性保障提出的挑战。对身份认同的理解应当从一种被动的、内在的、身体性的内省，转向主动的、积极的、实践性的创造。在此基础上，尝试构建一种关于技术自我的身份认同问题的实践性解释框架，并以此为出发点回应由于人们广泛使用互联网技术和人类增强技术而引发的关于身份认同的新问题。
In the 21st century, technology and its development are permeating every aspect of people's life comprehensively. In some key areas of technology, technological breakthroughs are having an increasingly important impact on people's lives and even on human itself. Along with these developments, technology is constantly redefining the profound meanings of the "self" and other related concepts, prompting a deep reflection on the self, the essential nature of the human beings as a person, the status of moral subjectivity, values, identity and their implications, and the changes that have occurred as a result. Therefore, the important question of "who am I", a traditional philosophy issue about human self-awareness, has been given a new meaning in the present technological age. The exploration of this issue must incorporate the important dimension of "technology", thus contributing to the growth of academic interest and the emergence of a new interdisciplinary research field. This interdisciplinary field of study is known as the "Technoself Study", which has emerged in recent years. As one of the core concepts in the field of technoself study, the concept of "technoself" integrates the concepts that reflect the relationship between human and technology/machine which have already occurred in the past social trend of thought. Its emphasis is on what kinds of changes have taken place in the current state of human being and in the relationship between the human being and technology, that occurred as a result of the adoption of technologies such as Internet technology and human enhancement technology. It also focuses on rethinking and discussion of how human beings recognize themselves and how to treat the relationship between technology and themselves caused by these changes. This paper focuses on the most important topic in the study of technoself, namely, personal identity. From two dimensions of time and technology, this paper re-examines, analyzes and refines the explanation of psychological continuity theory, narrative identity theory and bodily continuity theory of personal identity, as well as the discourse on the relationship between human and technology which put forward by Bernard Stigler and some other philosophers of technology, and pointing out that there are epistemological risks in the existing theories, which cannot well explain the emergence of the online personal identity, "avatar" and other new problems caused by Internet technologies, nor can it respond to the challenges presented by human enhancement technology to the body which as a mandatory guarantee of personal identity. The interpretation and understanding of personal identity should shift from a passive, internal and bodily introspection to a positive, active, and practical creation. On this basis, this paper attempts to construct a practical interpretive framework about the personal identity of technoself, and takes this as a starting point to respond to the new problems about the personal identity that have emerged as a result of the widespread use of Internet technologies and human enhancement technologies.
