洛克在《人类理解论》中把“感觉(sensation)”和“反思(reflection)”(1)看作是观念的两个来源,并认为一切简单观念都经由这两个途径进入心灵。不过,由于洛克最早将“反思”作为一个哲学概念加以使用,而且他对观念的这两个来源的论述确实有很多不够清楚、甚至不够融贯之处,尤其是未对反思到底如何为理解提供观念作出明确的阐释,从而导致了人们对“反思”这一概念在其观念起源论中的地位和作用的误解甚或 Locke views “sensation” and “reflection” (1) as two sources of ideas in “human understanding” and holds that all simple ideas are entered through these two paths soul. However, since Locke first used “reflection ” as a philosophical concept, and he did not elaborate on these two sources of ideas, and did not even find enough coherence. In particular, he did not reflect on Understanding provides a clear interpretation of the concept, leading to a misunderstanding of the status and role of the concept of “reflection” in its conceptual origin
