William Tenn's "Of All Possible Worlds" is a mid-20th-century science fiction novella that delves into the profound ethical and existential dilemmas of time travel. The narrative follows Max Alben, a desperate time traveler from a future ravaged by a catastrophic epidemic known as the Blight, tasked with a singular mission: to avert its origin in 1976 by deflecting a guided missile. As Alben navigates the past, he confronts not only the technical challenges of his mission but also the moral complexities of altering history, discovering a competing timeline and the grim reality that intervention may lead to unforeseen, equally dire outcomes. The story masterfully explores themes of human survival, the nature of fate, and the heavy burden of responsibility in a dystopian context, forcing both protagonist and reader to question the true meaning of 'the greater good.'

“"We thought we were saving the world, but perhaps we were merely choosing which hell to inhabit."”

Key themes

Time Travel Paradoxes and Consequences
The central theme exploring the intricate and often disastrous implications of altering historical events. The novella delves into the 'butterfly effect,' demonstrating how a single change in the past can ripple through time, creating entirely new and unforeseen futures that may be no better, or even worse, than the one initially sought to be prevented.
Human Responsibility and Intervention
This theme examines the moral obligation and the profound burden placed upon individuals and societies when faced with the power to alter destiny. It questions whether humanity has the wisdom to wield such power, and what constitutes a 'responsible' intervention when the outcomes are uncertain and potentially catastrophic.
Fate vs. Free Will
The novella deeply explores the tension between predetermined destiny and the capacity for individual choice. Max Alben's efforts to change the past raise questions about whether certain events are inevitable, or if conscious actions can truly alter the fundamental trajectory of history, regardless of the specific details.
