As a salute to a preeminent social scholar of our times, Immanuel M. Wallerstein (1930-2019), this paper briefly highlights his biography, education, and academic career; however, it is mainly concerned with his scholarly concepts and theories. The author attempts to follow the development process of one of his main contributions to social sciences, the world-systems approach, as well as to analyze various important aspects of it, including its historic and philosophic significance. All efforts have been made to keep the paper informative yet also accessible and transparent, deferring, when appropriate, to Immanuel Wallerstein himself to expound his ideas to the reader.
