Explanatory metaphysics aspires to explain the less fundamental in terms of the more fundamental. But we should recognize two importantly different approaches to this task. According to the generation approach, more basic features of reality generate (or give rise to) less basic features. According to the reduction approach, less perspicuous ways of representing reality reduce to (or collapse into) more perspicuous ways of representing reality. The main goals of this paper are to present the core differences between the two approaches (§2), to demonstrate the distinction's significance (§3), to provide some resources for adjudicating between the approaches (§4), and to argue that the project of explanatory metaphysics needs both (§5).

形而上学解释的两种方法

解释性形而上学渴望用更基本的东西来解释不太基本的东西。但我们应该认识到完成这项任务的两种重要的不同方法。根据生成方法，现实的更多基本特征会生成（或引起）不太基本的特征。根据简化方法，不太明显的表示现实的方式减少为（或崩溃为）更明显的表示现实的方式。本文的主要目标是呈现两种方法之间的核心差异（§2），论证差异的重要性（§3），为裁决两种方法提供一些资源（§4），并论证解释形而上学的项目需要两者（§5）。
