This article proposes a novel theory of the truth of doctrine. A signpost theory of the truth of doctrine is informed by practice-based philosophy of science. I argue that a theory of the truth of doctrine needs to explain the construction, use, and judgement of doctrine. So, I raise questions about the truth of doctrine in reference to the relation between a theory of the truth of doctrine and the role of doctrine in the religious practice of believers. I argue that a signpost theory of the truth of doctrine learns from an empirical understanding of measurement and modelling in scientific practice. The examples of entropy and time provide insights into the construction, use, and judgement of measurements and modelling in scientific practice. An empirical understanding of measurement in scientific practice provides resources for linking representations with reality without ignoring the contextual construction, use, and judgement of representations. I conclude with a brief articulation of how a signpost theory of the truth of doctrine learns from an empirical understanding of measurements and models in scientific practice by highlighting the similarities and differences between the construction, use, and judgement of doctrine and of scientific representations.

通过什么措施？教义真理的路标理论

本文提出了一种新颖的教义真理理论。学说真理的路标理论是基于基于实践的科学哲学的。我认为，教义真理理论需要解释教义的构造、使用和判断。因此，我就教义真理理论与教义在信徒宗教实践中的作用之间的关系提出了关于教义真理的问题。我认为，教义真理的路标理论是从对科学实践中测量和建模的经验理解中学习的。熵和时间的例子提供了对科学实践中测量和建模的构建、使用和判断的见解。对科学实践中测量的实证理解为将表征与现实联系起来提供了资源，同时又不忽视表征的语境构建、使用和判断。最后，我通过强调学说和科学表征的构建、使用和判断之间的异同，简要阐述了学说真理的路标理论如何从科学实践中对测量和模型的实证理解中学习。
