As physical things have mathematical properties we in this paper let mental things have biological properties. The work is based on recent metaphysical findings that shows that there could be interfaces between separate ontological domains. According to this view there could be mathematical objects, physical objects, and also mental objects. The aim of this study is to establish a view of the biological object that allows it to possibly generate the experiencing subject. Based on the notion that energy per se is related to the ability of a system to do some work, biological energy is defined as a biological object’s ability to recover from the load it is exposed to. Introducing the concept of the experiencing subject, the experiencing subject would be the agent experiencing the biological object’s need of recovery from the load it is exposed to. Once established, the experiencing subject may develop non-biological needs. On this basis experiencing subjects have biological properties without being biological in exactly the same manner as physical things have mathematical properties without being mathematical (would that be the case).

由于物理事物具有数学特性，因此我们在本文中让精神事物具有生物学特性。这项工作基于最近的形而上学发现，这些发现表明不同的本体域之间可能存在接口。根据这种观点，可能存在数学对象、物理对象和心理对象。这项研究的目的是建立一种生物对象的观点，使其可能产生体验主体。基于能量本身与系统做功的能力相关的概念，生物能量被定义为生物对象从其所承受的负载中恢复的能力。介绍体验主题的理念，体验主题将是代理经历生物对象的需要从它所承受的负载中恢复。一旦建立，体验对象可能会发展出非生物需求。在此基础上，体验主体具有生物学特性而不是生物学特性，这与物理事物具有数学特性而不是数学特性完全相同（如果是这样的话）。
