Knowledge and Exploration Theme Icon

The Hitchhiker’s Guide to the Galaxy often focuses on the pursuit of knowledge. Although Adams advocates for an acceptance of meaninglessness in the face of lofty existential questions, he also makes it clear that the impulse to explore such questions—to seek out knowledge—is a natural and inevitable part of being alive. In fact, he even suggests that this process of exploration and discovery is often more enticing than the act of actually settling on an answer. For example, the “hyperintelligent beings” that come to earth as mice are unrelenting in their efforts to understand the meaning of life, such that the very process of inquiry overtakes their aspirations to find definitive answers. Their philosophers are so wrapped up in contemplating life’s questions that they try to stop their fellow beings from building a computer—Deep Thought—that will provide an answer to “Life, the Universe and Everything.” This is because they want to continue debating the answer, and they know that any conclusion will put an end to their otherwise endless deliberations. Fortunately for them, Deep Thought needs 7,500,000 years to find the answer to “Life, the Universe and Everything,” thereby giving them a chance to postulate their own theories. This delights them, as they rejoice at the opportunity to simply keep exploring the topic of life. In turn, Adams suggests that the pursuit of knowledge is an activity that people take part in for its own sake. Spotlighting the ways living beings engage in intellectual discourse, he ultimately emphasizes that the desire to explore new ideas is often greater than the desire to secure actual answers.

Just before the mice are about to ask Deep Thought to tell them the answer to “Life, the Universe and Everything,” Adams demonstrates that some people—especially those who have committed their lives to knowledge and exploration—don’t actually want to hear such answers. This is made clear when two philosophers named Majikthise and Vroomfondel burst into the room and try to stop Deep Thought before he responds. “You just let the machines get on with the adding up, and we’ll take care of the eternal verities, thank you very much,” Majikthise says to one of the mice who built Deep Thought. “You want to check your legal position, you do, mate. Under law the Quest for Ultimate Truth is quite clearly the inalienable prerogative of your working thinkers. Any bloody machine goes and actually finds it and we’re straight out of a job, aren’t we? I mean, what’s the use of our sitting up half the night arguing that there may or may not be a God if this machine only goes and gives you his bleeding phone number the next morning?” According to Majikthise, machines should be used to solve simple problems, like those that revolve around “adding up” various numbers. Because he has devoted his entire life to “sitting up half the night arguing” about grand unanswerable questions, he doesn’t want Deep Thought to arrive at definitive conclusions about, for instance, the existence of God. Echoing this sentiment, his colleague adds: “That’s right, we demand rigidly defined areas of doubt and uncertainty!” Of course, this is a rather humorous “demand,” since “doubt and uncertainty” are by their very definitions vague and thus not “rigidly defined.” But this is precisely what the philosophers want to preserve: the kind of vagueness that invites intellectual exploration.

The philosopher mice aren’t the only characters in The Hitchhiker’s Guide to the Galaxy who avoid definitive answers while still pursuing knowledge. Indeed, Zaphod embarks upon an entire mission of exploration and discovery without even knowing what, exactly, he wants to get out of the experience. This is because he has gone into his own brain and rewired his synaptic network so that he won’t know why he wants to become president of the galaxy, steal the Heart of Gold spaceship, and find Magrathea, an old planet nobody believes exists. “I freewheel a lot,” he tells Arthur, Ford, and Trillian. “I get an idea to do something, and, hey, why not, I do it. I reckon I’ll become President of the Galaxy, and it just happens, it’s easy. I decide to steal this ship. I decide to look for Magrathea, and it all just happens.” However, he doesn’t know why he gets the “idea to do something.” Wanting to get to the bottom of this, he eventually runs a battery of tests on himself and finds his own initials cauterized into his brain tissue, right where an alteration was made that essentially makes it impossible for him to determine why he wants to do the things he’s doing. Because government officials run tests on the brain of any incoming president, Zaphod guesses that he purposefully altered himself so that no one would detect his plans to find Magrathea. As a result, though, he doesn’t know why he wants to find Magrathea. And yet, he pushes onward, undeterred. As such, his quest to find the planet takes on its own significance, as he blindly follows his impulse toward investigation. Rather than seeing exploration as a means to an end, Zaphod allows the process of discovery to be an end in and of itself. In turn, Adams presents the process of exploration and discovery—and the pursuit of knowledge—as an experience that is worth indulging even when its underlying reasons aren’t readily apparent.

Knowledge and Exploration Quotes in The Hitchhiker’s Guide to the Galaxy

Below you will find the important quotes in The Hitchhiker’s Guide to the Galaxy related to the theme of Knowledge and Exploration.
Preface Quotes

Far out in the uncharted backwaters of the unfashionable end of the Western Spiral arm of the Galaxy lies a small unregarded yellow sun. Orbiting this at a distance of roughly ninety-eight million miles is an utterly insignificant little blue-green planet whose ape-descended life forms are so amazingly primitive that they still think digital watches are a pretty neat idea.

This planet has—or rather had—a problem, which was this: most of the people living on it were unhappy for pretty much of the time. Many solutions were suggested for this problem, but most of these were largely concerned with the movements of small green pieces of paper, which is odd because on the whole it wasn’t the small green pieces of paper that were unhappy.

Chapter 1 Quotes

The word bulldozer wandered through his mind for a moment in search of something to connect with.

The bulldozer outside the kitchen window was quite a big one.

He stared at it.

“Yellow,” he thought, and stomped off back to his bedroom to get dressed.

Passing the bathroom he stopped to drink a large glass of water, and another. He began to suspect that he was hung over. Why was he hung over? Had he been drinking the night before? He supposed that he must have been. He caught a glint in the shaving mirror. “Yellow,” he thought, and stomped on to the bedroom.

Explanation and Analysis:

“But Mr. Dent, the plans have been available in the local planning office for the last nine months.”

“Oh yes, well, as soon as I heard I went straight round to see them, yesterday afternoon. You hadn’t exactly gone out of your way to call attention to them, had you? I mean, like actually telling anybody or anything.”

“But the plans were on display…”

“On display? I eventually had to go down to the cellar to find them.”

“That’s the display department.”

“With a flashlight.”

“Ah, well, the lights had probably gone.”

“So had the stairs.”

“But look, you found the notice, didn’t you?”

“Yes,” said Arthur, “yes I did. It was on display in the bottom of a locked filing cabinet stuck in a disused lavatory with a sign on the door saying ‘Beware of the Leopard.’”

Chapter 3 Quotes

Ford was very kind—he gave the barman another five-pound note and told him to keep the change. The barman looked at it and then looked at Ford. He suddenly shivered: he experienced a momentary sensation that he didn’t understand because no one on Earth had ever experienced it before. In moments of great stress, every life form that exists gives out a tiny subliminal signal. This signal simply communicates an exact and almost pathetic sense of how far that being is from the place of his birth. On Earth it is never possible to be farther than sixteen thousand miles from your birthplace, which really isn’t very far, so such signals are too minute to be noticed. Ford Prefect was at this moment under great stress, and he was born six hundred light-years away in the near vicinity of Betelgeuse.

The barman reeled for a moment, hit by a shocking, incomprehensible sense of distance. He didn’t know what it meant, but he looked at Ford Prefect with a new sense of respect, almost awe.

Explanation and Analysis:

This is Prostetnic Vogon Jeltz of the Galactic Hyperspace Planning Council,” the voice continued. “As you will no doubt be aware, the plans for development of the outlying regions of the Galaxy require the building of a hyperstpatial express route through your star system, and regrettably your planet is one of those scheduled for demolition. The process will take slightly less than two of your Earth minutes. Thank you.

The PA died away.

Uncomprehending terror settled on the watching people of Earth. […]

There’s no point in acting all surprised about it. All the planning charts and demolition orders have been on display in your local planning department in Alpha Centauri for fifty of your Earth years, so you’ve had plenty of time to lodge any formal complaint and it’s far too late to start making a fuss about it now.

Chapter 5 Quotes

One of the things Ford Prefect had always found hardest to understand about humans was their habit of continually stating and repeating the very very obvious, as in It’s a nice day, or You’re very tall, or Oh dear you seem to have fallen down a thirty-foot well, are you all right? At first Ford had formed a theory to account for this strange behavior. If human beings don’t keep exercising their lips, he thought, their mouths probably seize up. After a few months’ consideration and observation he abandoned this theory in favor of a new one. If they don’t keep on exercising their lips, he thought, their brains start working. After a while he abandoned this one as well as being obstructively cynical and decided he quite liked human beings after all, but he always remained desperately worried abut [sic] the terrible number of things they didn’t know about.

Chapter 6 Quotes

“Now it is such a bizarrely improbable coincidence that anything so mind-bogglingly useful could have evolved purely by chance that some thinkers have chosen to see it as a final and clinching proof of the non-existence of God.

“The argument goes something like this: ‘I refuse to prove that I exist,’ says God, ‘for proof denies faith, and without faith I am nothing.’

“ ‘But,’ says Man, ‘the Babel fish is a dead give-away, isn’t it? It could not have evolved by chance. It proves you exist, and so therefore, by your own arguments, you don’t. [...]’

“ ‘Oh, dear,’ says God, ‘I hadn’t thought of that,’ and promptly vanishes in a puff of logic.

“ ‘Oh, that was easy,’ says Man, and for an encore goes on to prove that black is white and gets himself killed on the next pedestrian crossing.”

Chapter 7 Quotes

“Yes, do continue…” invited the Vogon.

“Oh…and, er…interesting rhythmic devices too,” continued Arthur, “which seemed to counterpoint the…er…er…” he floundered.

Ford leaped to his rescue, hazarding “…counterpoint the surrealism of the underlying metaphor of the…er…” He floundered too, but Arthur was ready again.

“…humanity of the…”

Vogonity,” Ford hissed at him.

“Ah yes, Vogonity—sorry—of the poet’s compassionate soul”—Arthur felt he was on a homestretch now—“which contrives through the medium of the verse structure to sublimate this, transcend that, and come to terms with the fundamental dichotomies of the other”—he was reaching a triumphant crescendo—“and one is left with a profound and vivid insight into…into…er…” (which suddenly gave out on him). Ford leaped in with the coup de grace:

“Into whatever it was the poem was about!” he yelled.

Chapter 10 Quotes

The principle of generating small amounts of finite improbability by simply hooking the logic circuits of a Bambleweeny 57 Sub-Meson Brain to an atomic vector plotter suspended in a strong Brownian Motion producer (say a nice hot cup of tea) were of course well understood […]. [One] thing [scientists] couldn’t stand was the perpetual failure they encountered in trying to construct a machine which could generate the infinite improbability field needed to flip a spaceship across the mind-paralyzing distances between the farthest stars, and in the end they grumpily announced that such a machine was virtually impossible.

Then, one day, a student […] found himself reasoning this way:

If, he thought to himself, such a machine is a virtual impossibility, then it must logically be a finite improbability. So all I have to do in order to make one is to work out exactly how improbable it is, feed that figure into the finite improbability generator, give it a fresh cup of really hot tea…and turn it on!

Chapter 11 Quotes

He tapped irritably at a control panel. Trillian quietly moved his hand before he tapped anything important. Whatever Zaphod’s qualities of mind might include—dash, bravado, conceit—he was mechanically inept and could easily blow the ship up with an extravagant gesture. Trillian had come to suspect that the main reason he had had such a wild and successful life was that he never really understood the significance of anything he did.

Chapter 12 Quotes

One of the major difficulties Trillian experienced in her relationship with Zaphod was learning to distinguish between him pretending to be stupid just to get people off their guard, pretending to be stupid because he couldn’t be bothered to think and wanted someone else to do it for him, pretending to be outrageously stupid to hide the fact that he actually didn’t understand what was going on, and really being genuinely stupid. He was renowned for being amazingly clever and quite clearly was so—but not all the time, which obviously worried him, hence the act. He preferred people to be puzzled rather than contemptuous. This above all appeared to Trillian to be genuinely stupid, but she could no longer be bothered to argue about it.

Explanation and Analysis:

“Can we work out,” said Zaphod, “from their point of view what the Improbability of their rescue was?”

“Yes, that’s a constant,” said Trillian, “two to the power of two hundred and seventy-six thousand, seven hundred and nine to one against.”

“That’s high. They’re two lucky lucky guys.”


“But relative to what we were doing when the ship picked them up…”

Trillian punched up the figures. They showed two-to-the-power-of-Infinity-minus-one to one against (an irrational number that only has a conventional meaning in Improbability Physics).

Chapter 15 Quotes

Many men of course became extremely rich, but this was perfectly natural and nothing to be ashamed of because no one was really poor—at least no one worth speaking of. And for all the richest and most successful merchants life inevitably became rather dull and niggly, and they began to imagine that this was therefore the fault of the worlds they’d settled on. None of them was entirely satisfactory: either the climate wasn’t quite right in the later part of the afternoon, or the day was half an hour too long, or the sea was exactly the wrong shade of pink.

And thus were created the conditions for a staggering new form of specialist industry: custom-made luxury planet building. The home of this industry was the planet Magrathea, where hyperspatial engineers sucked matter through white holes in space to form it into dream planets—gold planets, platinum planets, soft rubber planets with lots of earthquakes—all lovingly made to meet the exacting standards that the Galaxy’s richest men naturally came to expect.

This is a complete record of [the sperm whale’s] thought from the moment it began its life till the moment it ended it.

Ah…! What’s happening? it thought.

Er, excuse me, who am I?


Why am I here? What’s my purpose in life?

What do I mean by who am I?

Calm down, get a grip now…oh! this is an interesting sensation, what is it? It’s a sort of…yawning, tingling sensation in my…my…well, I suppose I’d better start finding names for things if I want to make any headway in what for the sake of what I shall call an argument I shall call the world, so let’s call it my stomach.

[…] What’s this thing? This…let’s call it a tail—yeah, tail. Hey! I can really thrash it about pretty good, can’t I? Wow! Wow! That feels great! Doesn’t seem to achieve very much but I’ll probably find out what it’s for later on. Now, have I built up any coherent picture of things yet?

Chapter 24 Quotes

The car shot forward straight into the circle of light, and suddenly Arthur had a fairly clear idea of what infinity looked like.

It wasn’t infinity in fact. Infinity itself looks flat and uninteresting. Looking up into the night sky is looking into infinity—distance is incomprehensible and therefore meaningless. The chamber into which the aircar emerged was anything but infinite, it was just very very very big, so big that it gave the impression of infinity far better than infinity itself.

“I think the problem, to be quite honest with you, is that you’ve never actually known what the question is.”

“But it was the Great Question! The Ultimate Question of Life, the Universe and Everything,” howled Loonquawl.

“Yes,” said Deep Thought with the air of one who suffers fools gladly, “but what actually is it?”

A slow stupefied silence crept over the men as they stared at the computer and then at each other.

“Well, you know, it’s just Everything…everything…” offered Pouchg weakly.

“Exactly!” said Deep Thought. “So once you do know what the question actually is, you’ll know what the answer means.”

“Well, I mean, yes idealism, yes the dignity of pure research, yes the pursuit of truth in all its forms, but there comes a point I’m afraid where you begin to suspect that if there’s any real truth, it’s that the entire multidimensional infinity of the Universe is almost certainly being run by a bunch of maniacs. And if it comes to a choice between spending yet another ten million years finding that out, and on the other hand just taking the money and running, then I for one could do with the exercise.”
