This paper focuses on Hector‐Neri Castañeda's significant contributions to metaphilosophy. In his 1980 work, On Philosophical Method, Castañeda articulates a unique perspective, characterizing philosophy as fundamentally a dia‐philosophical activity. By asserting the supremacy of synthesis over analysis within the metaphilosophical hierarchy, his account provides a purely theoretical defense of philosophical pluralism devoid of any relativistic inclinations. Despite Castañeda's enduring influence and profound impact on ongoing discussions in ontology, logic, and the philosophy of language, his metaphilosophical insights have largely been neglected. In the context of today's increasingly diverse philosophical landscape, this paper posits that Castañeda's pluralist metaphilosophy retains substantial theoretical relevance.

作为双重哲学的哲学：赫克托-内里·卡斯塔涅达对多元主义的理论辩护

本文重点介绍赫克托·内里·卡斯塔涅达对元哲学的重大贡献。在他 1980 年的作品中，论哲学方法卡斯塔涅达阐述了一种独特的视角，将哲学从根本上描述为一种非哲学活动。通过断言元哲学层次中综合相对于分析的至高无上的地位，他的论述为哲学多元主义提供了纯粹的理论辩护，没有任何相对主义倾向。尽管卡斯塔涅达对本体论、逻辑学和语言哲学领域正在进行的讨论具有持久的影响和深远的影响，但他的元哲学见解在很大程度上被忽视了。在当今哲学格局日益多样化的背景下，本文认为卡斯塔涅达的多元元哲学保留了实质性的理论相关性。
