A thought experiment creates the intellectual conditions of playing out the consequences of a situation that need not be possible to construct in reality. In the case that the hypothetical situation is not possible to engineer, the conundrum is profoundly felt. There is no way to verify your stake, and any conclusions drawn are met with the caveat of fundamental uncertainty. The experiment develops only so far as the imagination is willing to play.

This holiday season, I have indulged in the secret pleasure of Stephen King. His new novel, 11/22/63, takes time travel as its premise and explores the effects of both intimate and large-scale alterations to the course of history. In the first case, you can try to imagine the grand discrepancies between your life having met your lover and your life had you not. In the latter case, you can try to imagine a world with atomic weapons and a world without. While I can easily entertain the idea that my life has been radically affected by certain people and events, it is harder to imagine a world markedly different than the one we’ve got because, at a social level, major transformations seem inevitable. Had Einstein not articulated that E=mc², then certainly some other brilliant mind would have, and still we’d be living with the sick threat of atomic warfare. It’s harder to imagine changing the course of the world than it is a single life if only because the zeitgeist of an era is dispersed, and though history attributes certain findings or events to individuals, I can easily imagine that the intellectual, political and cultural conditions of the time make these findings or events, in a certain way, inevitable.

But like all good thought experiments, I only get more wrapped up in the seeming contradictions of these questions the more I consider them. Surely some historical events are the product of a singular mind, and the awful, easy example to consider is the Holocaust. If it were possible to travel back in time and murder Hitler as a small child, it might be possible to avoid the Holocaust. But, if the Holocaust was as much a product of bureaucracy as it was a demented and hateful individual, would some other horrific genocide occur, an inevitable result of bureaucracy run amok? There’s no way to know these other worlds, only the weight of knowing that given what we’ve got, there is a moral obligation to reflect and act accordingly for the future. And yet, I wonder, do some lessons really need to be learnt? Could we not just avoid the whole mess altogether? And yet…
