在认知科学、逻辑学和语言哲学领域，模糊性一直是一个非常重要的概念。连锁悖论是由模糊性导致的主要问题之一。随着对模糊性与连锁悖论的不断探索，用以处理连锁悖论的不同方案也陆续被提出。这些方案在发展的过程中大多都遇到了一个相同的问题-高阶模糊性。目前对高阶模糊性相关问题还存在很多分歧，高阶模糊性的存在性问题、是否存在无穷阶模糊性的问题、引入确定性算子是否可以解决高阶模糊性的问题、高阶模糊性的引入是否可以消解连锁悖论的问题都存在争论。通过了解分析不同的立场与观点以及相关的描述与形式化，可以发现不同观点各自的优势及问题，同时也可以以全局性的视角对高阶模糊性相关问题进行整体梳理与总结。当前许多对高阶模糊性的刻画都专注于对容忍原则的讨论，以及用形式化的语言进行描述，试图找到对高阶模糊性的确定的某一种刻画形式，无一例外的都遇到了一些困难。实际上高阶模糊性的问题并不单单是由容忍原则导致的，而是要结合边界情形来进行说明。语境主义进路以一种独特的视角对高阶模糊性相关问题进行了阐释与刻画。容忍原则和边界情形作为两个被区别开来的概念在语境主义进路中被分别进行阐释。这二者虽然有一定联系，但并不一定是同时发生的。高阶模糊性其实主要是由边界情形导致的，当边界情形被引入作为一个分类时，高阶模糊性才会出现。在这个概念基础上，高阶模糊性的相关问题也都会有更加合理的解释。

In the fields of cognitive science, logic, and language philosophy, vagueness has always been a critically important concept. Sorites paradox is one of the main problems caused by vagueness. As research into vagueness and Sorites paradox continues, various approaches to addressing this paradox have been proposed. Most of these approaches encounter a common issue during their development - higher-order vagueness. Currently, there are many disagreements regarding issues related to higher-order vagueness, such as the existence of higher-order vagueness, the question of whether infinite degrees of vagueness exist, whether introducing determinacy operators can resolve issues of higher-order vagueness, and whether the introduction of higher-order vagueness can resolve Sorites paradoxes. By understanding and analyzing different stances, viewpoints, and related descriptions and formalizations, one can identify the strengths and problems of each viewpoint and also undertake a comprehensive overview and summary of issues related to higher-order vagueness from a global perspective.

Currently, many characterizations of higher-order vagueness focus on discussions of the tolerance principle and use formalized language for descriptions, attempting to find a definitive characterization of higher-order vagueness, invariably encountering various difficulties. In fact, the issues of higher-order vagueness are not solely caused by the tolerance principle，but needs to be explained in conjunction with borderline case. The contextualism approach offers a unique perspective on issues related to higher-order vagueness and provides interpretations and characterizations accordingly. The tolerance principle and boundary cases are two distinct concepts in the contextualism approach that are explained separately. Although they are related, they do not necessarily occur simultaneously. Higher-order vagueness is primarily caused by boundary cases, and it is only when boundary cases are introduced as a classification that higher-order vagueness appears. On this conceptual basis, issues related to higher-order vagueness can be more reasonably explained.
