現代社會的病態現象主要源自自我的囿限與封閉。於本文中，筆者首先介紹社會建構論式的心理治療方法，並透過Kenneth Gergen的關係存有學，闡明當代諮商輔導與心理治療理論轉向關係存有學的發展趨勢。其次，筆者將引入沈清松的建構實在論的觀點，探究外推作為一種意義重構與關係修復的建構療法之可行性。最後，筆者主張，外推不僅能夠作為復全之道的策略，以及作為修復關係的建構療法之實踐步驟，也為天主教社會哲學的研究開啟新的向度。

The pathological phenomenon of modern society mainly comes from the self-limitation and self-closure. In this paper, I will first introduce the social constructionist method of psychotherapy, and clarifies the development trend of contemporary consultation counseling and psychotherapy theory through the relational ontology of Kenneth Gergen. Secondly, I will introduce Vincent Shen’s constructive realistic perspective, and explore the feasibility of strangification as an approach of meaning reconstruction and relationship repair. Finally, I will advocate that strangification not only serve as a strategy of restoration, and as a practical step of social constructionist therapy to repair relationships, but also open up a new orientation for the study of Catholic social philosophy.
