基于特修斯悖论对历史建筑保护的同一性研究

Research on the Identity of Historic Building Conservation Based on Theseus Paradox

特修斯悖论及其衍生问题的实质是在探讨事物历经变化后能否继续保持“同一性”。通过思想实验、逻辑推理可知,功能不变、组成结构不变以及时空连续是事物保持“同一性”的三个必要条件。本文将同一性的概念应用于历史建筑保护,重新审视历史建筑保护中的原真性、完整性原则。历史建筑保持同一性是原真性、完整性成立的充分条件,也是历史建筑保护的核心工作和最高追求。

The essence of Theseus paradox and its derivatives is whether things could remain“identical”.Through thought experiments and logical reasoning,it is concluded that three necessary conditions are required to remain“identical”,namely unchanged functions,unchanged compositions and spatio-temporal continuity.This paper applies the concept of identity to historic building conservation,and re-examines the principles of originality and integrity.The identity of historic buildings is a sufficient condition for originality and integrity,and also the core as well as the ultimate goal of historic building conservation.
