This study aims to address the problems that occur when experts gain a significant amount of authority and power in every aspect of society. It also examines the sociological meaning of changes by non-experts, the amateurs, in modern society. This focus on amateurs started with the age of post-authoritarianism, from trusting in the power of common people in democratic society, where various concerns and values are freely expressed. Unlike the creativity of experts, the creativity of amateurs is creating a new culture by allowing anyone to create, enjoy, and share creative work. Common people respond to life crises by spontaneously solving problems within the various limitations that surround them. Furthermore, these people learn new ways and behaviors to live with different people, and they experiment with new methods of creation while appropriating the framework and objects made by experts. During this process, amateurs show us a new way of life that differs from existing creativity, knowledge, politics, and labor. The conclusion of this study explores the possibilities of sociology of amateur on a preliminary level. The Sociology of amateur is not limited to sociology “about” or “for” amateurs; rather this study aims to examine whether sociology “by” amateurs will be possible, since this is related to the issue of how we should respond to the crisis that sociology, which has pursued expertise as the highest value in our changed society, is currently facing.
