Oscillation is a core aspect of Metamodern thought and practice. It is the way people and ideas in the move back and forth between seemingly opposite attitudes or sensibilities, such as irony and sincerity, hope and doubt, or progress and nostalgia. Instead of settling in one extreme, oscillation embraces the tension between these poles, navigating uncertainty by engaging with both earnestness and skepticism. This "oscillation" is about flexibility, not indecision. It holds multiple perspectives, seeking meaning through a balance of openness, creativity, and self-awareness, as a practical and adaptive response to the complexities of contemporary life.
