分析与抽象：
分析是将信息处理的输入进行限制，一次只处理一点信息；然后进行综合；
分析的对象是整体；是信息分割；
抽象是信息的过滤与压缩；是将大块的信息抽离出关注的部分，然后进行处理的过程；
抽象的对象是整体；（基础是比较）。是信息抽离；
Conceptual abstractions may be formed by filtering the information content of a concept or an observable phenomenon, selecting only the aspects which are relevant for a particular subjectively valued purpose. For example, abstracting a leather soccer ball to the more general idea of a ball selects only the information on general ball attributes and behavior, excluding, but not eliminating, the other phenomenal and cognitive characteristics of that particular ball.[1] In a type–token distinction, a type (e.g., a 'ball') is more abstract than its tokens (e.g., 'that leather soccer ball').
An abstraction can be seen as a compression process,[4] mapping multiple different pieces of constituent data to a single piece of abstract data;[5] based on similarities in the constituent data, for example, many different physical cats map to the abstraction "CAT". This conceptual scheme emphasizes the inherent equality of both constituent and abstract data, thus avoiding problems arising from the distinction between "abstract" and "concrete". In this sense the process of abstraction entails the identification of similarities between objects, and the process of associating these objects with an abstraction (which is itself an object).

------------------越是喧嚣的世界，越需要宁静的思考------------------ 合抱之木，生于毫末；九层之台，起于垒土；千里之行，始于足下。 积土成山，风雨兴焉；积水成渊，蛟龙生焉；积善成德，而神明自得，圣心备焉。故不积跬步，无以至千里；不积小流，无以成江海。骐骥一跃，不能十步；驽马十驾，功在不舍。锲而舍之，朽木不折；锲而不舍，金石可镂。蚓无爪牙之利，筋骨之强，上食埃土，下饮黄泉，用心一也。蟹六跪而二螯，非蛇鳝之穴无可寄托者，用心躁也。
