The concept itself was introduced in the reimagined Battlestar Galactica series, which kicked off in 2004, and even this is rather significant. The 1978 series is largely the same on paper, but the tone and thematic focus of the 2004 reimagining shifted toward a darker, less optimistic look at the battles between good and evil, exploring moral ambiguity and humanity's cycles of destruction. That's where Battlestar Galactica's greatest quote comes in. "All of this has happened before. All of this will happen again" serves as the central prophecy of Battlestar Galactica (2004). It's initially spoken in season 1 by Cylon Leoben Conoy, but the words are repeated and applied to the plot and characters of each subsequent installment. The idea here is that any new moment of destruction and suffering has happened in just the same way in the past, and unless something deeply specific changes, it will all be repeated in the future. It's an infinite cycle, which is both a pessimistic and optimistic thought in Battlestar Galactica. Suffering is endless, but then, life will always endure, just as it has before. In Battlestar Galactica, the arc of each season further demonstrates to the characters that their experiences are the result of the endless cycle of humanity—a choice to create smart machines, oppress them, be betrayed, and suffer the consequences. By the end of Battlestar Galactica, a chance is presented to break the cycle, but the result is left ambiguous. The resonant question ultimately remains—will history repeat itself? "All Of This Has Happened Before. All Of This Will Happen Again" Is Even More Relevant Today Credits: MovieStillsDB Viewers can come to their own conclusion when they finish up Battlestar Galactica whether the cycle is truly broken. When it comes down to it, it simply depends on whether it's even possible for humanity to make different choices. It seems simple enough, and the evidence of history should demonstrate why humans shouldn't repeat the same catalyst that always begins the cycle. However, Battlestar Galactica essentially tells us that we never really learn our lesson. It's interesting that, just as this cycle repeats itself, Battlestar Galactica's central quote repeatedly becomes more relevant to society. When the reimagined series kicked off in the early 2000s, it immediately embraced a different tone than the 1978 show. Morality became ambiguous, and this time, humanity shared more responsibility. It's noteworthy that the new Battlestar Galactica hit the scene in the wake of the devastation of 9/11. It was a brand new terror experienced by the United States. Yet, the tragedy repeated what has infinitely happened before. It's now been two decades since Battlestar Galactica first embraced that quote, and the same amount of time since 9/11. Humanity has experienced several new horrors over those years, from wars and genocide to global pandemics. However, these are all things our species has faced time and time again for thousands of years. The cycle has yet to be broken, and Battlestar Galactica suggests that it might never be. Of course, the show also demonstrates that the cycle of survival will also repeat. One can't be true without the other. Battlestar Galactica's Most Famous Quote Comes From Peter Pan Interestingly, Battlestar Galactica isn't the first time that this exact quote has been used in media. Disney's 1953 Peter Pan movie opens with the narration (from Tom Conway) of "All this has happened before, and it will all happen again. But this time it happened in London. It happened on a quiet street in Bloomsbury." Here, the quote is different and yet the same. Peter Pan takes a more optimistic approach to the line, though it is bittersweet. This story emphasizes that the process of growing up is repeated infinitely, as long as humanity persists. Children's innocence fades away, and though they try to hold onto it, the time always comes to grow up. Peter Pan is the exception, but his immortal childlike wonder comes at a cost. Is it worth it? Whether we consider humanity's transition from peace to destruction a parallel to the children of Peter Pan growing up, or if the choice to maintain childlike wonder and "believe" even in adulthood represents the occasional breaking of the cycle, there's a lot to be gleaned here. Battlestar Galactica took a thoughtful concept and turned it dark, while also reminding us that there is a lighter side to the coin. Release Date 2004 - 2009-00-00 Network SyFy Showrunner Ronald D.
