Conceptual engineering is the method for assessing and improving our representational devices. On its ‘broad-spectrum’ version, it is expected to be appropriately applicable to any of our representation-involving cognitive activities, with major consequences for our whole cognitive life. This paper is about the theoretical foundations of conceptual engineering thus characterised. With a view to ensuring the actionability of conceptual engineering as a broad-spectrum method, it addresses the issue of how best to construe the subject matter of conceptual engineering and successively defends the theses that conceptual engineering should be: (i) About concepts, (ii) psychologically theorised, (iii) as multiply realised functional kinds. Thereby, I claim to theoretically secure and justify the maximum scope, flexibility, and impact for the method of conceptual engineering on our representational devices in our whole cognitive life—in other words, a broad-spectrum version of conceptual engineering.

广谱概念工程

概念工程是评估和改进我们的代表性设备的方法。在其“广谱”版本中，它有望适当地适用于我们任何涉及表征的认知活动，并对我们的整个认知生活产生重大影响。本文是关于由此表征的概念工程的理论基础。为了确保概念工程作为一种广谱方法的可操作性，它解决了如何最好地解释概念工程主题的问题，并相继捍卫了概念工程应该是：（i）关于概念，（ ii）心理理论化，（iii）作为多重实现的功能类型。因此，我声称在理论上确保并证明最大范围、灵活性、
