On the Dialectic Nature of Human Mind: The Dynamic Tension Between Sameness and non-Sameness.

Abstract

Although our environments and ourselves are usually thought about as relatively stable over time, there is always a tension between sameness and non-sameness in our lives. Because any development is considered as emerging non-sameness, I report that the inquiry into the development of human mind must regard this tension as essential. In this paper, first I show that this tension is a highly relational and dynamic phenomenon that cannot be fixed or measured in numerical terms. Non-sameness is not only a result of development but also a ground that leads to further development in the future. After illustrating the function and regulation of the {same <> non-same} tension in development by analyzing an excerpt from a mother-child conversation, I explain that this tension, or more generally the dialectic nature, is within the core of psychological phenomena, in terms that were introduced to psychology by James Mark Baldwin a century ago. These discussions imply the importance of inquiring into the process of development that emerges from the dialectic tension and fluctuations of our movements and that is observable in various relationships, including the relationship between researchers and study participants.
