This paper summarizes the historical and contemporary importance of mental action in philosophy. Not every piece of mental activity is a mental action. A mental action is something you do mentally, and something for which you as a whole person are responsible. It can be something you do as a means to doing something else, in the case of complex (i.e. non-basic) mental actions. The fact that you can perform complex mental actions implies that some thoughts have several contents under the several descriptions under which they are intentional. The nature of mental action helps to explain how you have special self-knowledge of your own mental states. It also helps to explain how certain kinds of norms, including epistemic norms, gain application to thought.

心理活动

本文总结了精神活动在哲学中的历史和当代重要性。并非每一个心理活动都是心理活动。精神行为是您在精神上所做的事情，并且您作为一个完整的人对此负责。在复杂的（即非基本的）心理行为的情况下，它可以是你做的事情作为做其他事情的一种手段。您可以执行复杂的心理行为这一事实意味着某些想法在它们有意的几种描述下具有多种内容。心理行为的性质有助于解释您如何对自己的心理状态有特殊的自我认识。它还有助于解释某些类型的规范，包括认知规范，如何应用于思想。
