Some of our most prominent metaphysicians have argued for a notion of naturalness that combines the roles of joint-carving, fundamentality, and perfect similarity. This paper argues that it is a mistake to think that there are select properties fulfilling all these roles. Toward this end, epistemologically tractable diagnostic markers for naturalness are presented. From these it follows that there can be perfect naturalness and similarity at nonfundamental levels; and the fundamental need not be perfectly natural or yield perfect similarities. Metaphysicians of naturalness are encouraged to attend to insights from metaphysical property theory and the interdisciplinary study of patterns and complexity, both of which support these conclusions. Distinct metaphysical projects are distinguished.

自然的、基本的和完全相似的：解开形而上学的辫子

我们的一些最杰出的形而上学家主张一种自然性的概念，它结合了共同雕刻、基本性和完美相似性的作用。本文认为，认为有选择的属性可以满足所有这些角色是错误的。为此，提出了认识论上易于处理的自然性诊断标记。从这些可以得出，在非基本层面上可以存在完美的自然性和相似性；基本原则不必是完全自然的或产生完全相似的。鼓励自然的形而上学家关注形而上学属性理论的见解以及模式和复杂性的跨学科研究，这两者都支持这些结论。不同的形而上学项目是有区别的。
