The mystique of solidarity retains its allure. The power of solidarity defies imagination. Yet harnessing this power has proven to be a challenge. There is much about solidarity to be learned. This study seeks a deeper understanding of solidarity that is necessary to find a way of using the enormous creative potential of solidarity more effectively for human progress and liberation. The article shows that the dominant theory and practice of solidarity are incapable to realize this objective. The article argues that attraction to differences is the main source of solidarity’s power. Affirmation and empowerment of differences is the key to creating strong and enduring social bonds that can sustain solidarity. Yet the dominant conception of solidarity requires subjugation of differences to the central point of identification and their suppression. The article proposes a new approach toward solidarity. The distinct feature of this approach is its view of differences. In contrast to the traditional view that sees differences primarily as opposed to each other, the article outlines a new conception of solidarity that views differences as the most important resource for human advancement and liberation. The article examines the theoretical and practical implications of the new conception.
