In his eight volume (and one novella) series The Dark Tower Stephen King presents a reader with an image of a world similar to our own, or it could even be argued, an alternate version of its very own future tainted by germ warfare and a nuclear catastrophe of disastrous global consequences. Throughout the series, King draws upon various elements commonly present in futuristic and post-apocalyptic sci-fi novels (even though The Dark Tower does not fall, in its own right, solely under that single genre) one of them also being the possibility of travelling through time and traversing freely the boundaries between parallel universes. In the first book of the series King acquaints the reader with the character of Roland Deschain, the last gunslinger on an epic quest to reach the now collapsing Dark Tower which is believed to be the nexus of all existence containing within itself all that is space and time. Throughout the entire duration of Roland’s quest, the reader is confronted with many a philosophical issue stemming from the notion of the collapsing Tower causing time and space to change and distort. The grandfather paradox and the bootstrap paradox (both temporal paradoxes) are only two of many philosophical issues put forth by King in what can be considered his magnum opus. I will hereby try to accentuate the significance of time and various temporal paradoxes and demonstrate why the understanding of the aforementioned in the novels is crucial for successful and more comprehensible reading of the series.
