本文試圖瞭解台灣佛教團體為何有的放生？有的不放生？從行動 者的角度，解析宗教信念及其放生風險（即動物風險和生態風險）的評估，與佛教團體的放生／不放生以及如何放生的關連。本研究發現，宗教信念不僅提供放生的動機與目的，也是放生團體化解放生風險內在矛盾和弔詭的解藥。放生的本質在於宗教倫理的實踐，當放生與動物倫理或生命倫理衝突時，放生者必須從宗教信念（如動機論和慧命觀）合理化放生的弔詭，或者致力發展新的放生技術來降低動物風險。台灣佛教內部對放生有關的各種宗教信念，有著複雜的解讀與認知歧義，放生理由不限於一種動機或目的，而不放生者所抱持的理由亦不盡相同，其中包括肯定放生的初衷，但因顧慮放生風險而不放生的例子。放生者之間又因動機與目的，以及對放生的動物風險和生態風險的認知差異，衍生出不同的放生技術和方式。多數改進放生方式的團體，重視動物風險多於生態風險。有的放生團體認為生態風險是可控制的，有的認為生態風險是佛教的外部問題。放生作為一種宗教實踐與行動，無論是否成為教團發展與吸引信眾的一種策略，宗教信念的支持是正當化與合理化宗教行動的必要論述。

This paper attempts to clarify the reasons why certain Taiwanese Buddhist groups do animal release, whereas others do not. Based on the actors' viewpoints, this research tries to identify the religious ideas and to categorize the ways that the evaluation of animal risk and ecological risk in the events of animal release relate to the attitudes and behaviors of Taiwanese Buddhist groups. The results show that religious thoughts not only convey the ethics of animal release, but serve as antidotes to dissolve the paradox of animal release. The practices of animal release among Taiwanese Buddhist groups are also quite diversified. The reasons and ways of both doing and not doing animal release have various patterns that imply different religious assessments. Some releasersmodified the ways of animal releasing with better control of animal risk and/or ecological risk. Some releasers maintain that ecological risk is manageable; some releasers treat ecological risk as an irrelevant or external issue to Buddhism. Although animal release could be a strategy to mobilize followers, religious ideas and interpretations are critical to the rationalization and justification of animal release.
