Given the idea that Life as we know it is nothing but a special form of a generically underlying dynamical structure within the physical Universe, we try to introduce a concept of Life that is not only derived from first principles of fundamental physics, but also metaphysically based on philosophical assumptions about the foundations of the world. After clarifying the terminology somewhat, especially with a view to differentiating reality from modality, we give an example for a mathematical representation of what the substance of reality (in the traditional sense of metaphysics) could actually mean today, discussing twistor theory as an example. We then concentrate on the points of structural emergence by discussing the emergence of dynamical systems and of Life as we know it, respectively. Some further consequences as they relate to meaning are discussed in the end.

重新审视天体生物学的哲学方面

考虑到我们所知道的生命只不过是物理宇宙中一般潜在动力学结构的一种特殊形式，我们试图引入一个生命概念，它不仅源自基础物理学的第一原理，而且还基于形而上学关于世界基础的哲学假设。在对术语进行了一些澄清之后，特别是为了区分现实与模态，我们举了一个例子来说明现实的实质（在传统的形而上学意义上）在今天实际上可能意味着什么，并以扭曲理论为例进行讨论。然后，我们分别讨论动力系统的出现和我们所知的生命的出现，从而专注于结构出现的要点。
