Key takeaways

  • A Scanner Darkly belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect A Scanner Darkly to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of A Scanner Darkly from memory before moving on to harder problems.

Reference excerpt

A Scanner Darkly is a science fiction novel by American writer Philip K. Dick, published in 1977. The semi-autobiographical story is set in a dystopian Orange County, California, in the then-future of June 1994, and includes an extensive portrayal of drug culture and drug use (both recreational and abusive). The novel is one of Dick's best-known works and served as the basis for a 2006 film of the same name, directed by Richard Linklater.

Plot summary The protagonist is Bob Arctor, member of a household of drug users, who is also living a double life as an undercover police agent assigned to spy on Arctor's household. Arctor shields his identity from those in the drug subculture and from the police. (The requirement that narcotics agents remain anonymous, to avoid collusion and other forms of corruption, becomes a critical plot point late in the book.) While posing as a drug user, Arctor becomes addicted to "Substance D" (also referred to as "Slow Death", "Death" or "D"), a powerful psychoactive drug. A conflict is Arctor's love for Donna, a drug dealer, through whom he intends to identify high-level dealers of Substance D. When performing his work as an undercover agent, Arctor goes by the name "Fred" and wears a "scramble suit" that conceals his identity from other officers. Then he is able to sit in a police facility and observe his housemates through "holo-scanners", audio-visual surveillance devices that are placed throughout the house. Arctor's use of the drug causes the two hemispheres of his brain to function independently or "compete". When Arctor sees himself in the videos saved by the scanners, he does not realize that it is him. Through a series of drug and psychological tests, Arctor's superiors at work discover that his addiction has made him incapable of performing his job as a narcotics agent. They do not know his identity because he wears the scramble suit, but when his police supervisor suggests to him that he might be Bob Arctor, he is confused and thinks it cannot be possible. Donna takes Arctor to "New-Path", a rehabilitation clinic, just as he begins to experience the symptoms of Substance D withdrawal. It is revealed that Donna has been a narcotics agent all along, working as part of a police operation to infiltrate New-Path and determine its funding source. Without his knowledge, Arctor has been selected to penetrate the organization. As part of the rehab program, Arctor is renamed "Bruce" and forced to participate in cruel group-dynamic games, intended to break the will of the patients. The story ends with Bruce working at a New-Path farming commune, where he is experiencing a serious neurocognitive deficit, after withdrawing from Substance D. Although considered by his handlers to be nothing more than a walking shell of a man, "Bruce" manages to spot rows of blue flowers growing hidden among rows of corn and realizes that the blue flowers are Mors ontologica, the source of Substance D. The book ends with Bruce hiding a flower in his shoe to give to his "friends"—undercover police agents posing as recovering addicts at the Santa Ana New-Path facility—on Thanksgiving.

Autobiographical nature A Scanner Darkly is a fictionalized account of real events, based on Dick's experiences in the 1970s drug culture. Dick said in an interview, "Everything in A Scanner Darkly I actually saw." Between mid-1970 (when his fourth wife Nancy left him) and mid-1972, Dick lived semi-communally with a rotating group of mostly teenage drug users at his home in Marin County, described in a letter as being located at 707 Hacienda Way, Santa Venetia. Dick explained, "[M]y wife Nancy left me in 1970. I got mixed up with a lot of street people, just to have somebody to fill the house. She left me with a four-bedroom, two-bathroom house and nobody living in it but me. So I just filled it with street people and I got mixed up with a lot of people who were into drugs." During this period, the author ceased writing completely and became fully dependent upon amphetamines, which he had been using intermittently for many years. "I did take amphetamines for years in order to be able to—I was able to produce 68 final pages of copy a day," Dick said. The character of Donna was inspired by an older teenager who became associated with Dick sometime in 1970; though they never became lovers, the woman was his principal female companion until early 1972, when Dick left for Canada to deliver a speech to a Vancouver science fiction convention. This speech, "The Android and the Human", served as the basis for many of the recurring themes and motifs in the ensuing novel. Another turning point in this timeframe for Dick is the alleged burglary of his home and theft of his papers. After delivering "The Android and the Human", Dick became a participant in X-Kalay (a Canadian Synanon-type recovery program), effortlessly convincing program caseworkers that he was nursing a heroin addiction to do so. Dick's recovery program participation was portrayed in the posthumously released book The Dark Haired Girl (a collection of letters and journals from this period, most of a romantic nature). It was at X-Kalay, while doing publicity for the facility, that he devised the notion of rehab centers being used to secretly harvest drugs (thus inspiring the book's New-Path clinics). In the afterword, Dick dedicates the book to those of his friends—he includes himself—who had experienced debilitation or death as a result of their drug use. Mirroring the epilogue are the involuntary goodbyes that occur throughout the story—the constant turnover and burn-out of young people that lived with Dick during those years. In the afterword, he states that the novel is about "some people who were punished entirely too much for what they did", and that "drug misuse is not a disease, it is a decision, like the decision to move out in front of a moving car".

Worked examples

Example 1 — a first encounter with A Scanner Darkly

Start with the simplest possible case. Write down what A Scanner Darkly claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to A Scanner Darkly before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about A Scanner Darkly ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of A Scanner Darkly

In research
A Scanner Darkly appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses A Scanner Darkly in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
A Scanner Darkly is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1977 American novels, 1977 English-language novels, 1977 science fiction novels, so understanding it makes those chapters shorter.
In everyday life
Look for A Scanner Darkly outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
