A City Guide To Zhuhai for The complexity of human language allows for the development of reason. Reason might be defined as the capacity to think logically, to deliberate coherently, and to infer consistently. Reason allows one to separate, contrast, and combine thoughts so as to establish sustained chains and patterns of ideas. Language, in combination with reason, vastly extends our mental reach. This intellectual extension, and the creative and analytical power it allows, accounts for the development of our technology.
