Not the Sum of its Parts: One of the most obvious differences between complex adaptive systems and Newtonian mechanical systems is that the former is not the sum of its parts. A mechanical system like a car is the sum total of all its parts as put together to an “intelligent design”. In contrast, a city is more than the sum of all the buildings and a biological ecosystem is not just the sum of all the plants and animals. This is why complex adaptive systems cannot be described neatly from any one perspective. Thus, English language cannot be defined through even the most detailed description of its grammar. Similarly, the most detailed description of the Taj Mahal would not define the city of Agra. Yet, speakers of English -and the citizens of Agra have little difficultly identifying and using the language and city respectively. The same is true of Hindus – their seeming difficulty in defining Sanatan Dharma poses no problem in recognizing and practicing their religion.
