本文通过区分模型背后的时间概念，回顾了对现实进行建模的各种方法。简要描述和分析了物理理论中预设的时间基本概念，包括考虑的描述级别、观察者与世界其他部分之间假设的界面切割、由此产生的观察者视角以及这些概念基于时间自然约束的程度。物理理论中的时间概念是次要的概念，源自我们对时间的主要经验。因此，我们必须将我们的理论视为以人类为中心的——源自我们的具体认知所产生的抽象和隐喻。基于分形时间和分形时空概念的理论是概括或替代描述，允许对现实进行更加差异化的建模。由此产生的时间观察者视角可以进一步区分。分形时间的概念在逻辑上先于分形时空的概念，因为它基于时间的主要经验：连续性、同时性、持续时间和扩展的现在。在此背景下，观察者的内部分化及其有意识和无意识情境化的程度成为我们现实生成游戏的重要组成部分。我充分意识到，这里提出的概念选择既不完整也不公正，并且受到我自己的时间观察者视角的影响。
This paper reviews various approaches to modelling reality by differentiating notions of time which underly those models. Basic notions of time presupposed in physical theories are briefly described and analyzed in terms of the levels of description taken into account, the interfacial cut assumed between the observer and the rest of the world, the resulting observer perspectives and the extent to which these notions are based on temporal natural constraints. Notions of time in physical theories are secondary constructs, derived from our primary experiences of time. Therefore, we must regard our theories as anthropocentric - derived from abstractions and metaphors resulting from our embodied cognition. Theories based on the notion of fractal time and fractal space-time are generalizations or alternative descriptions which allow for a more differentiated modelling of reality. The resulting temporal observer perspectives allow for further differentiation. The notion of fractal time logically precedes those of fractal space-time, as it is based on the primary experiences of time: succession, simultaneity, duration and an extended Now. Against this background, the internal differentiation of the observer and his degree of both conscious and unconscious contextualization turn out to be vital ingredients in our reality generation game. I am fully aware of the fact that the selection of concepts presented here is neither complete nor unbiased and is coloured by my own temporal observer perspective.
