"Philosophy and The Hitchhiker’s Guide to the Galaxy" is a collection that philosophizes _via_ the wonderful _Hitchhiker_ books by Douglas Adams. The goal isn't to assume you're already a philosophy buff, so please, Don't Panic!. However, it does expect you to have a bit of curiosity about philosophical matters. And really, if you love _Hitchhiker’s_, the authors reckon you're likely already interested in philosophy anyway, because, let's face it, Adams's work is brimming with it. The book itself is described as a "marvellous vehicle for popular philosophy". This isn't meant to be dry, academic stuff that requires a degree to understand. It aims to introduce philosophy in a way that's accessible and intriguing, doing justice to the philosophical aspects of _Hitchhiker’s_ without becoming overly academic or, at the other extreme, just "pop philosophy" that lacks real substance. It's a careful balance, trying to be popular and accessible while still genuinely engaging with philosophical ideas. Why use _Hitchhiker’s_, you might ask? Because Adams's biographer noted that he "loved philosophical ideas, and had a natural grasp of them". And indeed, _Hitchhiker’s_ isn't just sprinkled with philosophical concepts; it's absolutely "stuffed full of philosophical ideas and of philosophical questions". The most famous one is, of course, the 'Ultimate Question' of 'Life, the Universe and Everything'. But there are so many others lurking in the pages (and radio waves, and TV screens...). Think about some of these philosophical questions that pop up in _Hitchhiker’s_ and are explored in the book: - Can machines genuinely think? And can they have emotions? The characters of Colin the Happy Robot and Marvin the very unhappy robot offer quite a contrast to chew on here. - What makes a person, well, _that_ person? The question of personal identity comes up when we consider the two versions of Tricia McMillan/Trillian. Even the poor whale unexpectedly brought into existence by the Infinite Improbability Drive asks, "What do I mean by who am I?". - Is it okay to eat animals? And how important is consent in ethical decisions? This is famously highlighted by the animal that presents itself in _Restaurant at the End of the Universe_, eager to be eaten. - Does God exist? And if so, is God subject to the rules of logic? The notion of God vanishing in a "puff of logic" in the first book certainly raises eyebrows. - Who should hold political power or authority? The Galactic Presidency and, even more intriguingly, The Man Who Rules the Universe, make you think about this. - What makes work valuable? Characters like the Golgafrinchams, the Vogon guard complaining about his minutes being lousy, and Arthur's stint as a sandwich maker all touch upon this. There's also a recurring satirical jab at insurance, marketing, and advertising. - What is the nature and value of art and beauty? The Vogons, with their terrible poetry and disdain for beautiful things, provide a unique perspective. - How do we know what we know, and what are the grounds for that knowledge? The Man Who Rules the Universe's skeptical view on knowing others' experiences challenges our assumptions about knowledge. - What does it mean to feel 'at home'? Arthur Dent, constantly displaced, and even Douglas Adams himself, who reportedly felt somewhat out of place, embody this question. So, what makes these questions philosophical? It's a tough question even for philosophers. But generally, philosophical questions are those that seem to have better or worse answers, meaning they aren't just nonsense, but we don't have obvious ways to tackle them like experiments or surveys. To grapple with them, we rely on clear thinking, a deep desire to understand, and looking at how these problems have been approached in the past. As the philosopher Ludwig Wittgenstein put it, "a philosophical problem has the form: 'I don’t know my way about'". They are, in essence, peculiarly baffling issues. Some philosophical questions, especially in metaphysics, try to tie everything together into a comprehensive understanding of how things "hang together". Sometimes, philosophers even question if a seemingly philosophical problem is genuinely baffling or if another discipline could handle it. The book doesn't just point out that _Hitchhiker’s_ _contains_ philosophical ideas; it also considers whether the work itself might make philosophical _claims_. Douglas Adams apparently didn't read much philosophy and even tried to discourage a thesis on the philosophical themes in his work. However, the book suggests that _Hitchhiker’s_ itself might have philosophical ideas embedded implicitly, perhaps even ideas Adams wasn't fully aware of or didn't want to acknowledge. Adams's enthusiasm for natural science, particularly the life sciences (note his initials, DNA!), is reflected in his work, with jokes about evolution, the Infinite Improbability Drive, parallel worlds, and quantum physics. This love of science might even suggest a leaning towards "scientism," the idea that many philosophical problems could eventually be solved by science. _Hitchhiker’s_ characters like Vroomfondel and Majikthise, portrayed as self-interested philosophical buffoons, and Adams's admiration for Richard Dawkins (who critiqued those "educationally over-endowed with the tools of philosophy") might support this idea of a scientistic or anti-philosophical stance. However, the book argues that regardless of Adams's personal views or explicit intentions, _Hitchhiker’s_ is likely to contain some philosophical substance, even if it's presented in a scientistic or implicitly anti-philosophical way. The book's project is, broadly, to philosophize _via_ the _Hitchhiker_ books. It does this in two main ways: 1. **Philosophising with Hitchhiker’s:** This involves engaging directly with what the authors see as philosophical views expressed within the _Hitchhiker_ books. 2. **Philosophising from Hitchhiker’s:** This uses material from the series as a jumping-off point or stimulus for exploring philosophical topics more generally. Often, a single chapter might blend both approaches. The ultimate point is to make philosophy accessible while still being genuinely philosophical, suitable for readers interested in the intersection of Adams's stories and deep thinking. So, how does the book tackle all this? It's organized into four main parts: **Part I: Ethics** This section dives into moral questions raised by _Hitchhiker’s_. For instance, one chapter, "'Eat Me': Vegetarianism and Consenting Animals," explores the ethics of eating animals, focusing on the bizarre scene in _Restaurant at the End of the Universe_ where an animal wants to be eaten. It looks at arguments for vegetarianism and the complex idea of consent, especially when that consent might be influenced by power dynamics (like animals bred specifically to want to be eaten). The chapter even suggests that breeding an animal to want to be eaten might be wrong, giving Arthur a reason to stick to salad even in that strange situation. Another chapter in this part considers the ethics of entertainment, prompted by passages in _Hitchhiker’s_, like the one about Random and the Lamuellans. It asks whether certain forms of violent entertainment are acceptable or if they are harmful or objectionable. _Ideas to explore further:_ Could consent ever truly justify eating an animal bred for that purpose? What are the real-world parallels to power dynamics influencing seemingly free choices? Does fictional violence make us more or less empathetic in reality? **Part II: The Meaning of Life** This part tackles the big questions about existence. One chapter, "Life, the Universe and Everything," suggests that _Hitchhiker’s_ can be seen as a long reflection on the absurdity of human existence. It links this to the feeling many of us have of being insignificant in the vast cosmos, much like the whale pondering its existence as it falls towards a planet. The chapter explores philosophical responses to this absurdity, comparing Adams's perspective (which might be similar to philosopher Albert Camus's idea of embracing absurdity). Camus saw turning to religion as an evasion, a kind of philosophical suicide, and _Hitchhiker’s_ seems to echo this skepticism about finding solace in a higher being. The idea that our lives might have a purpose just because a higher being designed them doesn't seem to escape absurdity in _Hitchhiker’s_, especially if that being isn't necessarily benevolent or sane. Absurdity, in this context, can arise from the clash between our human desire for clarity and meaning and the universe's fundamental unintelligibility. Or, as philosopher Thomas Nagel suggests (differing slightly from Camus), it might come from the conflict between our serious internal perspective on our lives and the detached, external perspective we can also take, which highlights our insignificance. The book proposes that Adams's approach, much like philosopher David Hume's response to skepticism, is to not necessarily solve or defuse the problem of absurdity intellectually, but rather to engage with life and its activities so fully that the worries fade away. Finding projects, even simple ones like learning bird language or mapping stars, can help push worries of absurdity aside. The chapter concludes that a good attitude towards absurdity might be "benign neglect". Another chapter in this section considers eternal life, prompted by the character Wowbagger the Infinitely Prolonged. It addresses philosopher Bernard Williams's argument that unending life would become intolerably boring, suggesting that an endless life _could_ be meaningful, and that the reasons why offer insights into what makes _any_ life meaningful. Wowbagger's chosen purpose – insulting everyone in the universe – is presented as a perverse way of coping with infinite tedium. _Ideas to explore further:_ How does engaging in projects or finding personal purpose truly address cosmic absurdity, or does it just distract us? Is "benign neglect" a philosophical position or just avoiding the issue? What could make an eternal life meaningful, and how does that relate to meaning in a finite life? **Part III: Metaphysics and Artificial Intelligence** This part delves into big questions about reality and consciousness. A chapter by Jerry Goodenough, "'I Think You Ought to Know I’m Feeling Very Depressed': Marvin and Artificial Intelligence," argues that Marvin the Paranoid Android is interesting because he defies typical science fiction portrayals of intelligent robots. Usually, sci-fi robots are either emotionless or mindlessly cheerful. Marvin, however, is distinctly and deeply unhappy. This difference is presented as philosophically informative, suggesting that for artificial intelligence to be truly intelligent, it might need the capacity for real feelings, which could include severe unhappiness. Thinking about why Marvin is the way he is can help us understand human minds too. Another chapter, "From Deep Thought to Digital Metaphysics," starts with the outlandish _Hitchhiker’s_ idea that Earth was a giant computer built by hyperintelligent beings (manifesting as mice) to find the Ultimate Question. This premise serves as a springboard to explore mind-bending scenarios. Could our Earth really be a computer?. Could our entire universe be a computer, with reality being fundamentally computational?. If so, a perfect computer simulation would be just as real as the original. This possibility leads to the idea of universes nested within universes, possibly run by aliens or even future humans. We might, in effect, be characters in a sophisticated computer game. Even if reality isn't computational at its core, the sources suggest there are reasons to think we might likely be living in a machine-generated virtual reality. This connects to real-world ideas like digital physics, which proposes that information is the basic ingredient of the physical world, more fundamental than matter or energy. Some digital physicists argue that if the universe is digital, it must be discrete (not infinitely divisible like continuous space and time in traditional physics), which could align with ideas in string theory and loop quantum gravity, theories trying to reconcile quantum mechanics and general relativity. The chapter also touches on the idea, shared by physicist Edward Fredkin and Adams, that our universe might have been set up by some higher agency to find the answer to a question. Adams also played with the idea of "electronically synthesised universes" within the Guide itself, raising questions about virtual worlds and whether they are physically real or just appear to be. _Ideas to explore further:_ What are the implications if genuine artificial intelligence requires emotions? If we are living in a simulation, does anything we do truly matter? What would it mean for reality to be fundamentally computational? **Part IV: Logic, Method and Satire** This final part explores how _Hitchhiker’s_ engages with logic, philosophical methods, and functions as satire. One chapter, "'God . . . Promptly Vanishes in a Puff of Logic'," dissects the "Babel Fish argument" against God's existence found in _Hitchhiker’s_. The argument suggests that the incredibly improbable existence of the Babel fish (which instantly translates any language) is such strong _proof_ of God's existence that, according to God's own logic ("proof denies faith, and without faith I am nothing"), God must therefore not exist. The chapter examines this argument using logical tools, distinguishing descriptive claims from evaluative judgments, noting that subjective elements like 'oddest' or 'mindbogglingly useful' can be weaknesses in an argument. It also touches on the Argument from Design (which the Babel Fish argument incorporates) and the philosophical tradition where God's existence requires a "leap of faith" rather than rational proof. The chapter delights in the idea of God being subject to logic, suggesting that mastery of logic gives us a kind of power of thought, placing us on a level with or even beyond God. However, it also cautions against logical fallacies like the _ad hominem_ fallacy, reminding us not to dismiss an argument just because the person making it (like theologians or philosophers with vested interests) might be biased. Next, Andrew Aberdein's chapter, "The Judo Principle, Philosophical Method and the Logic of Jokes," looks at a creative problem-solving technique Adams used. Faced with the seemingly inescapable predicament of Arthur and Ford being thrown into space, Adams got the idea from judo to "use this problem to solve itself". The Infinite Improbability Drive works on this "Judo Principle," where the sheer improbability of something happening _causes_ it to happen. The chapter argues this principle is also significant in philosophical methodology. It's applied to various philosophical problems Adams touched on, such as defining infinity, the foundations of knowledge (like Descartes's _Cogito_ - "I think therefore I am," which Deep Thought replicates), artificial intelligence (like Alan Turing's test for machine intelligence, which focuses on indistinguishability), and parallel worlds (connecting Adams's ideas to the many-worlds interpretation of quantum mechanics). The chapter notes that applying the Judo Principle can take different forms, from simply "biting the bullet" and accepting a counter-intuitive conclusion (like David Lewis's view on modal realism and possible worlds) to the most sophisticated level, which involves the "logic of jokes". Adams's phrase "the logic of jokes" is taken seriously, suggesting that jokes, especially those using apparent nonsense, play a crucial role in human reasoning by highlighting malfunctions in common sense logic and using analogy and metaphor. The chapter argues that the logic of jokes isn't just something to tolerate in philosophy but a valuable problem-solving technique, echoing Ludwig Wittgenstein's idea that a serious philosophical work could consist entirely of jokes. Finally, Alexander Pawlak and Nicholas Joll discuss "The Funniest of All Improbable Worlds – Hitchhiker’s as Philosophical Satire". They argue that _Hitchhiker’s_ functions as philosophical satire. First, it satirizes science fiction itself, parodying common SF tropes like competent robots (Marvin is neurotic), grand explanations (Adams offers absurd ones like 42 or a message apologizing for inconvenience), and technological glorification (Adams highlights tech annoyances and flaws). Second, it functions as broader satire in the vein of Jonathan Swift's _Gulliver’s Travels_, using fantastical alien races (like the bureaucratic Vogons or feckless Golgafrinchams, identified as our ancestors) as distorted mirrors reflecting human follies and vices. It also satirizes bureaucracy, marketing, advertising, and even a gentle satire of Englishness through Arthur Dent. Third, and importantly, _Hitchhiker’s_ directly satirizes philosophy, portraying philosophers like Vroomfondel and Majikthise as self-serving buffoons more interested in gravy trains than eternal verities. However, the chapter argues it goes further than just making fun _of_ philosophy; it contains philosophy _as_ satire. This includes satirical jabs at simplistic or complacent philosophies that lose touch with reality. It also ventures into ethical and political satire through its depictions of societies and characters. A key way it operates as philosophy _as_ satire is through its extensive use of "perspective shifts". Like philosophers such as Hume, Kant, or Husserl who invite us to see things from unnatural or different viewpoints, Adams constantly shifts perspective to make things look ridiculous or doubtful, challenging deep assumptions about society, sanity, and reality itself. Finally, drawing parallels with Voltaire's satire _Candide_ (which lampooned Leibniz's optimistic idea that this is the "best of all possible worlds"), the chapter argues that _Hitchhiker’s_ satirizes the _quest for ultimate truth_, particularly the idea that life has some intrinsic or objective meaning waiting to be discovered. The absurdity of 42, the destruction of Earth before the Question is found, and the farcical nature of the universe all serve to mock the idea of intrinsic meaning. However, like Voltaire who, despite critiquing rigid optimism, still suggested cultivating one's garden as a response to a chaotic world, _Hitchhiker’s_ offers a more positive philosophical message: perhaps the lack of intrinsic purpose isn't a problem. Realizing there's no inherent meaning can be liberating, allowing us to create our own purposes or simply appreciate the "utter, inordinate, complexity and richness and strangeness" of the universe, finding reasons to hang around and make our lives worthwhile. _Ideas to explore further:_ Can satire be a valid philosophical method? How does challenging assumptions through perspective shifts help us understand philosophical problems? Is the satire of the quest for meaning in _Hitchhiker’s_ a form of pessimism or a call to find meaning ourselves? How does Adams's potential scientism interact with his satire of philosophy?
