After 63 Years & 16 Regenerations, This Is Still The Best Line In Doctor Who History

With its scientific jargon, quantum maneuvering, and ethical dilemmas, one common thread that has followed Doctor Who throughout its entire history is the ability to say something meaningful. That has been true from the First Doctor's encounter with Stone Age tribes to the Fifteenth Doctor's victory over the Ranis. Naturally, then, Doctor Who has offered up many pearls of wisdom over its long lifetime. Each incarnation of The Doctor has their own small handbook of intelligent musings and inspirational monologs, and even if the storylines and lore became more convoluted in Doctor Who's modern episodes, both eras of the show were equally adept at sounding clever. The honor of uttering the greatest line in Doctor Who must, however, go to Tom Baker's Fourth Doctor. The Doctor's definitive regeneration during the show's most fruitful period, it comes as little surprise that Baker also delivered Doctor Who's most important quote. From "Genesis of the Daleks," the line itself is simply, "Do I have the right?" This comes from a larger exchange with Sarah Jane Smith that goes as follows: DOCTOR: Just touch these two strands together and the Daleks are finished. Have I that right? SARAH: To destroy the Daleks? You can't doubt it. DOCTOR: Well, I do. You see, some things could be better with the Daleks. Many future worlds will become allies just because of their fear of the Daleks. SARAH: But it isn't like that. DOCTOR: But the final responsibility is mine, and mine alone. Listen, if someone who knew the future pointed out a child to you and told you that that child would grow up totally evil, to be a ruthless dictator who would destroy millions of lives, could you then kill that child? SARAH: We're talking about the Daleks, the most evil creatures ever invented. You must destroy them. You must complete your mission for the Time Lords. DOCTOR: Do I have the right? Simply touch one wire against the other and that's it. The Daleks cease to exist. Hundreds of millions of people, thousands of generations can live without fear, in peace, and never even know the word Dalek. SARAH: Then why wait? If it was a disease or some sort of bacteria you were destroying, you wouldn't hesitate. DOCTOR: But I kill, wipe out a whole intelligent lifeform, then I become like them. I'd be no better than the Daleks. Why Doctor Who's "Do I Have The Right?" Line Still Hasn't Been Topped Doctor Who had found itself in philosophical moods before "Genesis of the Daleks," but not quite to the same extent. The Fourth Doctor's speech on Skaro incorporated themes of genocide, utilitarianism, godhood, and sentience. This wasn't just a single-topic issue, but a whole TARDIS full of difficult questions. When does an organism become a living being? What rights should all living beings have (even the bad ones)? Does a higher yield of good outweigh an act of evil? And since when did Sarah Jane get so violent? Even in its deeper moments, Doctor Who traditionally took a black-and-white view on morality, but "Genesis of the Daleks" went against the grain and avoided easy answers. The Doctor's dilemma was ended due to an interruption, and while he eventually did decide to detonate the Dalek incubation room, the decision was taken out of his hands when an unwitting Dalek accidentally triggered the blast without The Doctor's involvement. Doctor Who never did answer the "Do I have the right?" question, and that ambiguity only made the line more powerful. The Impact Of "Do I Have The Right?" Is Still Felt In Modern Doctor Who "Do I have the right?" stands head and shoulders above other iconic Doctor Who quotes in large part because it involves The Doctor questioning themselves for once. Whenever the show delves into ethical hang-wringing, The Doctor usually assumes the moral high ground, effectively saying, "You're wrong, I'm right, and here's why" in a verbose and inspirational way. That's as true in the modern era as it was for the classic years. Very rarely do matters of ethics and philosophy force The Doctor into actually doubting themselves, so when the Fourth Doctor begins asking that question in "Genesis of the Daleks," the moment feels severe and shocking. It's a thread Doctor Who has occasionally picked up in the years since, most memorably with the Tenth Doctor's Time Lord Victorious arc, as Tennant's character declared himself master over time and placed himself above all rules of the universe. Ten's ego was eventually brought crashing down to reality, leaving The Doctor bouncing between hubris and humility ever since. And it all began with Tom Baker holding two bits of wire and asking, "Do I have the right?" Perhaps this is what makes Doctor Who's "Genesis of the Daleks" quote extra-special. The line doesn't just speak to the show's themes, or the wider struggle between good and evil in sci-fi as a whole. Those five words provide a glimpse into The Doctor's very soul. The pit of self-doubt and the repressed god complex that are core to The Doctor's persona briefly rose to the surface during that argument with Sarah Jane. It could be said that no other scene in Doctor Who history captures the character so perfectly.
