Argumentative Essay On Time Travel

Good Essays

Time travel has been debated for years by philosophers and non-philosophers alike. While the possibility of time travel is intriguing and alluring, I do not believe its portrayal in today’s media is plausible. In this paper, I will argue that time travel, particularly back in time, is not possible in our current world and universe. For the sake of clarity, I would like to specify that I will not be arguing from a physics-based standpoint, but rather from a logically-derived argument. Additionally, I will not venture into the possibility of time travel if parallel timelines existed. Let us define time travel as David Lewis does in his work, “The Paradoxes of Time Travel”:
What is time travel? Inevitably, it involves a discrepancy between time and time. Any traveler departs and then arrives at his destination; the time elapsed from departure to arrival (positive, or perhaps zero) is the duration of the journey. But if he is a time traveler, the separation in time between departure and arrival does not equal the duration of his journey. He departs; he travels for an hour, let us say; then he arrives. The time he reaches is not the time one hour after his departure. It is later, if he has traveled toward the future; earlier, if he has traveled toward the past. If he has traveled far toward the past, it is earlier even than his departure (p. 145). First, I invite the reader to consider their own life. Every event in the reader’s life has led them to where they are at this very moment, reading this essay. Even the slightest change in their past could have influenced them to not read this essay, but in just so happened that every moment contributed to a series of moments that resulted in reading these words. If a time traveler, be it the reader themselves or somebody else, went back in time to a time before this essay was read, they would not be able to change the sequence of events that lead to our current present. Lewis illustrates this point with the story of Tim and his grandfather. He maintains that Tim cannot kill his grandfather, even if he has all the necessary skills and attributes, because it would contradict the past he lived through (p. 149). He provides an example in which Tim may be able to kill his
