What are the building blocks of a theory?
Very interesting presentation by John Holland. John provided a useful model for looking into the real world phenomena, using Complex Adaptive Systems (CAS). His example of building a facial outlook using building blocks well illustrates the combination of different features of human to come up with different human faces. He mentioned that language is a CAS and could be built using building blocks.
In Chinese characters as illustrated here in wikipedia, different characters could be built using basic building blocks (characters), based on sound, or shape, or resemblance of certain objects or directions etc.
