Information theory provides a quantitative conceptual framework for understanding the flow of information from the world into and through brains. It focuses our attention on the sets of possible messages a brain's anatomy and physiology enable it to receive. The meanings of the messages arise from the inferences licensed by the brain's processing of them. Different meanings arise at different levels because different representations of the input license different inferences.

信息理论提供了一个定量的概念框架，用于理解信息从世界流入和经过大脑的过程。它将我们的注意力集中在大脑的解剖结构和生理学使其能够接收的一系列可能的消息上。消息的含义来自大脑处理它们所许可的推理。在不同的层次上会出现不同的含义，因为输入的不同表示许可不同的推论。
