Possible roles of cognitive science: As the third class of science of paraphraser brain

Abstract

In his seminal paper Possible roles of psychology in the very distant future, Masanao Toda has given his perspective on the long-term development of our society, science, and technology. In his perspective, which I call the development-in-parallel hypothesis, human-social science was expected to develop in parallel to the development of natural science. In contrast to this hypothesis, I will propose the development-in-nested-structure hypothesis, which states that natural science on general things is needed to launch information science on computer as a special class of things, and information science on general computers is needed to launch cognitive science on brain as a special class of computers. I discuss the possible roles of cognitive science in the future: Cognitive science needs to play a central role in leading the third class of science.
