Design research involving practice (i.e., practice-based and practice-led research) can be seen to offer a unique approach to knowledge production grounded in imagination and transformation. Yet, in spite of this apparent uniqueness, the approach largely lacks a justificatory epistemological narrative—a way of describing and qualifying its underlying theory of knowledge. It takes the view that any attempt to frame such a narrative requires deep philosophic engagement. This article aims to cohere the perspectives of three key philosophers—Dewey, Wittgenstein, and Heidegger—drawing their voices together around the coupled themes of experience-being, language-meaning, and knowing-truth and representing the whole in design terms.

界定研究中设计实践的正当性叙述：杜威、维特根斯坦和海德格尔的一些认识论交叉点

涉及实践的设计研究（即基于实践和以实践为主导的研究）可以被视为提供了一种基于想象和转化的知识生产的独特方法。然而，尽管有这种明显的独特性，但该方法在很大程度上缺乏正当的认识论叙述——一种描述和限定其基础知识理论的方式。它认为，任何构建这种叙述的尝试都需要深入的哲学参与。本文旨在凝聚三位主要哲学家——杜威、维特根斯坦和海德格尔——的观点，围绕经验存在、语言意义和认识真相这三个耦合主题，并以设计术语代表整体。
