于本文，筆者主要以沈清松教授的天主教社會哲學為例，證成當代中華新士林哲學具有關係存有學的轉向。首先，筆者將沈清松的哲學區分為對比哲學、慷慨外推與宗教交談三個發展階段。其次，筆者將透過沈清松的天主教社會哲學的思想，證成當代中華新士林哲學已經對關係存有學的轉向有所關注。最後，在筆者看來，沈清松立基於天主愛德的關係存有學基礎之上，成功地將「慷慨外推、邁向多元他者」轉譯為可理解的跨文化語言與主題對象，並具體發展成為具有可普遍化與可實踐性的現代規範性的行動準則，使其能在我們的真實生活世界中，發揮指引行動的有效性與實踐性的力量。

In this paper, I mainly take Professor Vincent Shen’s catholic social philosophy as an example to prove that the contemporary Chinese Neo-Scholasticism has shown a trend towards relational ontological turn. First of all, I will divide Vincent Shen’s philosophical thinking into three stages of development: contrastive philosophy, generous strangification, and interreligious dialogue. Secondly, I will justify through the thought of Vincent Shen’s catholic social philosophy that the contemporary Chinese Neo-Scholasticism has been a focus on relational ontological turn. Finally, in my personal opinion, Vincent Shen’s catholic social philosophical foundation is based on the relational ontology of God’s love and charity. He successfully translated the “generous strangification, toward many others” into an understandable cross-cultural language and subject, and it can develop into a modern standard with universalizability and practicability, so that this ethical norm can produce the effective and practical power of guiding activities in our real world of life.
