Abstract This paper studies unawareness in terms of the lack of knowledge in a model that generalizes both a non-partitional standard-state-space model and a stationary generalized-state-space model. The resulting model may not necessarily satisfy AU Introspection: an agent, who is unaware of an event, is unaware of being unaware of it. Yet, the paper shows that such agent does not know whether she is unaware of it, i.e., she is ignorant of being unaware of it. First, the paper asks when and how the generalized model (in particular, a standard-state-space model) has a non-trivial form of unawareness and sensible properties of unawareness. Second, the paper studies the implications of the violation of AU Introspection. An agent, when facing infinitely many objects of knowledge, may know that there is an event of which she is unaware. Treating new information only at face value can cause an agent to become unaware of some event.

没有 AU 内省的无意识

摘要 本文研究了在泛化非分区标准状态空间模型和平稳广义状态空间模型的模型中缺乏知识方面的无意识。结果模型可能不一定满足 AU 自省：不知道事件的代理，不知道自己不知道它。然而，论文表明，这样的代理人不知道她是否不知道，即她不知道自己不知道。首先，论文询问了广义模型（特别是标准状态空间模型）何时以及如何具有非意识的非平凡形式和非意识的合理属性。其次，本文研究了违反 AU Introspection 的影响。一个智能体在面对无限多的知识对象时，可能知道存在她不知道的事件。
