马克思恩格斯从四个方面论述了人的工具特性:现实中的个人不仅是自身的目的,而且是实现自身目的的手段或工具;人与人之间不仅是互为目的的,而且是互为工具的;人在生产社会并与社会相互依存中和与自然的相互关系中体现了人的工具性。完整、全面、准确地理解马克思恩格斯关于人的工具性的论述,对于落实科学发展观、倡导“以人为本”和构建社会主义和谐社会具有重大现实意义。 Marx and Engels discusses the characteristics of human tools from four aspects: the reality of individuals not only for their own purposes, but also to achieve their own goals or tools; between people is not only for the purpose of each other, but also as a tool for each other The human tool is embodied in the interrelationship between production society, social interdependence and nature. A complete, comprehensive and accurate understanding of Marx’s and Engels’s expositions on the instrumentalities of man has great practical significance for implementing the scientific concept of development, advocating “people-oriented” and building a socialist harmonious society.
