论文摘要
在先前的工作中，我们认为时空功能主义提供了工具，以阐明与时空出现在某些量子重力方法中的概念上的困难。我们在本文中认为，量子重力中的时空功能主义与量子力学和一般相对性提出的其他功能主义方法根本不同：与后一种情况相反，它与纯粹的解释性替代方案相反，但与量子层次的物理理论相互交织。时空功能主义允许在量子重力的背景下表达连贯的现实主义观点，并将其与对一般相对性的直接现实主义理解相关联。
In prior work, we have argued that spacetime functionalism provides tools for clarifying the conceptual difficulties specifically linked to the emergence of spacetime in certain approaches to quantum gravity. We argue in this article that spacetime functionalism in quantum gravity is radically different from other functionalist approaches that have been suggested in quantum mechanics and general relativity: in contrast to these latter cases, it does not compete with purely interpretative alternatives, but is rather intertwined with the physical theorizing itself at the level of quantum gravity. Spacetime functionalism allows one to articulate a coherent realist perspective in the context of quantum gravity, and to relate it to a straightforward realist understanding of general relativity.
