It’s possible to choose between being the captain or the co-pilot of your dreams. Lucid dreaming is a phenomenon that sees people taking control of the narrative of their dreams, often with thrilling results. Always wanted to fly? You can lift right off. Hungry for a giant cheeseburger? Dive right in.
Practitioners say that the technique requires discipline and patience to master. But there are also chemical shortcuts: supplements that seem to bring conscious control of the unconscious within reach for many. What’s more, the science behind these drugs says they likely work. However, unanswered questions about their safety and efficacy remain.

Help With Dreaming

Finding a drug that opens the door to lucid dreams is no new pursuit: In 1988, one researcher found a food supplement called DMAE might help, though evidence is slim. Currently, a few different compounds meant to treat dementia are in vogue amid the lucid dreaming community. For example, a drug called galantamine is used to treat people with Alzheimer’s disease. It can have side effects such as nausea and dizziness, although these are rare.

But lucid dreamers discovered that it can significantly increase dream recall and the odds of having lucid dreams. Galantamine can be purchased over-the-counter on Amazon, where some products even advertise lucid dreaming as a side effect.
Tests aimed specifically at exploring its effects on dreams seem to back these claims up. In 2018, galantamine was given to 121 patients in a double-blind, placebo-controlled trial, the only study of its kind. The patients were also given some instruction in lucid dreaming beforehand, so they didn’t come to the practice cold. But the results were still impressive. Some participants saw as much as a 42 percent increase in their ability to lucid dream, compared to self-reports from the past six months. Ten people experienced a lucid dream for the first time.
The results took researchers by surprise, according to Benjamin Baird, a postdoctoral research fellow at the Center for Sleep and Consciousness at the University of Wisconsin-Madison involved in the study. “It worked amazingly,” Baird says. “It was not at all clear that it would be this powerful of an effect.”
While the researchers aren’t sure yet why galantamine stimulates dream control, they have a clue. The drug blocks the breakdown of acetylcholine (ACh), an important neurotransmitter involved in learning, memory and REM sleep. The theory is that galantamine allows ACh to build up, leading to greater recollection and awareness during dreaming.
This is backed up by evidence that a few other dementia drugs that similarly block ACh breakdown also seem to increase vivid dreams. However, these other drugs haven’t been tested in clinical trials for this purpose, Baird says, so we don’t really know how well they work in comparison. For the moment, there’s really only the single trial with galantamine for scientists to go on.

Pills for Dreams

However, some companies aren’t waiting for clinical data on different blends of lucid dream stimulators. A prominent example is Dream Leaf, a Utah company that sells many herbs, including galantamine. Their namesake product, however, is two red and blue pills, in a not-so-subtle nod to The Matrix. The blue pill contains mugwort and valerian root, two herbs commonly used for insomnia. Dream Leaf says they augment REM sleep, a phase in the sleep cycle when most dreaming occurs.
The red pill contains three chemicals related to ACh: choline, and two dementia drugs called alpha-GPC and huperzine A. There’s no hard evidence that any of these substances help with lucid dreaming, alone or in combination, Baird says. Alpha-GPC, for example, has been tested for lucid dreaming specifically, but no difference was found against placebo. Huperzine A, however, does block ACh breakdown like galantamine, so it could work in a similar way.
“We need more research really,” Baird says. “A lot of these other substances really haven’t been tested properly.” In the meantime, he doesn’t recommend taking unnecessary supplements.

False Promises?

There are other supplements littering the internet with similar promises, often with a proprietary blend of ingredients like huperzine A or galantamine. There are anecdotal reports that they work, but it could also come down to the placebo effect, says Baird. “Expectation and anticipation play a strong role in lucid dreaming,” he says. “If you have a really strong expectation like that it could have an influence.”
Some over-the-counter pills make a lot of promises — weight loss, potent sexual energy, mental prowess — but dream control is a relatively new one. While exploring the lucid dreaming world is attractive to some people, taking dementia drugs purchased online comes with its own set of risks. Without more clinical trials, we won’t know how effective or how safe these drugs are.
Or, you could simply try achieving a lucid dream without any chemical crutches. One of the most common methods is called Mnemonic Induction of Lucid Dreams (MILD), developed by Stephen LaBerge, a psychophysiologist and lucid dreaming expert. It’s a memory training technique that can help with dream recall, such as remembering to look for a “dreamsign,” or indicator that you’re dreaming. (The most popular example of this is the spinning top in Inception.)
Teaching yourself the MILD technique can require some trial and error, but Baird says he experienced a lucid dream the first night he tried it. Before taking a pill from an online vendor, it might be worth experimenting with the chemicals already in your brain.

Allegory of the Cave

From Wikipedia, the free encyclopedia
Jump to navigationJump to search
Plato's Allegory of the Cave by Jan Saenredam, according to Cornelis van Haarlem, 1604, Albertina, Vienna
The Allegory of the Cave, or Plato's Cave, was presented by the Greek philosopher Plato in his work Republic (514a–520a) to compare "the effect of education (παιδεία) and the lack of it on our nature". It is written as a dialogue between Plato's brother Glaucon and his mentor Socrates, narrated by the latter. The allegory is presented after the analogy of the sun (508b–509c) and the analogy of the divided line (509d–511e). All three are characterized in relation to dialectic at the end of Books VII and VIII (531d–534e).
Plato has Socrates describe a group of people who have lived chained to the wall of a cave all of their lives, facing a blank wall. The people watch shadows projected on the wall from objects passing in front of a fire behind them, and give names to these shadows. The shadows are the prisoners' reality. Socrates explains how the philosopher is like a prisoner who is freed from the cave and comes to understand that the shadows on the wall are not reality at all, for he can perceive the true form of reality rather than the manufactured reality that is the shadows seen by the prisoners. The inmates of this place do not even desire to leave their prison, for they know no better life. The prisoners manage to break their bonds one day, and discover that their reality was not what they thought it was. They discovered the sun, which Plato uses as an analogy for the fire that man cannot see behind. Like the fire that cast light on the walls of the cave, the human condition is forever bound to the impressions that are received through the senses. Even if these interpretations (or, in Kantian terminology, intuitions) are an absurd misrepresentation of reality, we cannot somehow break free from the bonds of our human condition—we cannot free ourselves from phenomenal state just as the prisoners could not free themselves from their chains. If, however, we were to miraculously escape our bondage, we would find a world that we could not understand—the sun is incomprehensible for someone who has never seen it. In other words, we would encounter another "realm", a place incomprehensible because, theoretically, it is the source of a higher reality than the one we have always known; it is the realm of pure Form, pure fact.[1]
Socrates remarks that this allegory can be paired with previous writings, namely the analogy of the sun and the analogy of the divided line.

Terminology[edit]

The allegory of the cave is also called the analogy of the cave, myth of the cave, metaphor of the cave, parable of the cave, and Plato's Cave.[2]

Summary[edit]

Allegory of the Cave. Left (From top to bottom): The Sun; natural things; reflections of natural things; fire; artificial objects; shadows of artificial objects; Allegory level.
Right (From top to bottom): "Good" idea, Ideas, Mathematical objects, Light, Creatures and Objects, Image, Analogy of the Sun, and the Analogy of the Divided Line.

Imprisonment in the cave[edit]

Plato begins by having Socrates ask Glaucon to imagine a cave where people have been imprisoned from childhood (important to note that they were (based on text) imprisoned from childhood not from birth). These prisoners are chained so that their legs and necks are fixed, forcing them to gaze at the wall in front of them and not look around at the cave, each other, or themselves (514a–b).[3] Behind the prisoners is a fire, and between the fire and the prisoners is a raised walkway with a low wall, behind which people walk carrying objects or puppets "of men and other living things" (514b).[3] The people walk behind the wall so their bodies do not cast shadows for the prisoners to see, but the objects they carry do ("just as puppet showmen have screens in front of them at which they work their puppets" (514a)[3]). The prisoners cannot see any of what is happening behind them, they are only able to see the shadows cast upon the cave wall in front of them. The sounds of the people talking echo off the walls, and the prisoners believe these sounds come from the shadows (514c).[3]
Socrates suggests that the shadows are reality for the prisoners because they have never seen anything else; they do not realize that what they see are shadows of objects in front of a fire, much less that these objects are inspired by real things outside the cave which they do not see (514b-515a).[3]
The fire, or human made light, and the puppets, used to make shadows, are done by the artists. This can be compared to how illusions are made with light and sound today, with electronics, videos, movies, and 3D visuals. Plato, however, indicates that the fire is also the political doctrine that is taught in a nation state. The artists use light and shadows to teach the dominant doctrines of a time and place.
Also, few humans will ever escape the cave. This is not some easy task, and only a true philosopher, with decades of preparation, would be able to leave the cave, up the steep incline. Most humans will live at the bottom of the cave, and a small few will be the major artists that project the shadows with the use of human made light.

Departure from the cave[edit]

Plato then supposes that one prisoner is freed. This prisoner would look around and see the fire. The light would hurt his eyes and make it difficult for him to see the objects casting the shadows. If he were told that what he is seeing is real instead of the other version of reality he sees on the wall, he would not believe it. In his pain, Plato continues, the freed prisoner would turn away and run back to what he is accustomed to (that is, the shadows of the carried objects). He writes "... it would hurt his eyes, and he would escape by turning away to the things which he was able to look at, and these he would believe to be clearer than what was being shown to him."[3]
Plato continues: "Suppose... that someone should drag him... by force, up the rough ascent, the steep way up, and never stop until he could drag him out into the light of the sun."[3] The prisoner would be angry and in pain, and this would only worsen when the radiant light of the sun overwhelms his eyes and blinds him.[3]
"Slowly, his eyes adjust to the light of the sun. First he can only see shadows. Gradually he can see the reflections of people and things in water and then later see the people and things themselves. Eventually, he is able to look at the stars and moon at night until finally he can look upon the sun itself (516a)."[3] Only after he can look straight at the sun "is he able to reason about it" and what it is (516b).[3] (See also Plato's Analogy of the Sun, which occurs near the end of The Republic, Book VI.[4][5])

Return to the cave[edit]

Plato continues, saying that the freed prisoner would think that the world outside the cave was superior to the world he experienced in the cave and attempt to share this with the prisoners remaining in the cave attempting to bring them onto the journey he had just endured; "he would bless himself for the change, and pity [the other prisoners]" and would want to bring his fellow cave dwellers out of the cave and into the sunlight (516c).[3]
The returning prisoner, whose eyes have become accustomed to the sunlight, would be blind when he re-enters the cave, just as he was when he was first exposed to the sun (516e).[3] The prisoners, according to Plato, would infer from the returning man's blindness that the journey out of the cave had harmed him and that they should not undertake a similar journey. Plato concludes that the prisoners, if they were able, would therefore reach out and kill anyone who attempted to drag them out of the cave (517a).[3]

Symbolism[edit]

The allegory contains many forms of symbolism used to instruct the reader in the nature of perception. The cave represents superficial physical reality. It also represents ignorance, as those in the cave live accepting what they see at face value. Ignorance is further represented by the darkness that engulfs them because they cannot know the true objects that form the shadows, leading them to believe the shadows are the true forms of the objects. The chains that prevent the prisoners from leaving the cave represent that they are trapped in ignorance, as the chains are stopping them from learning the truth. The shadows cast on the walls of the cave represent the superficial truth, which is the illusion that the prisoners see in the cave. The freed prisoner represents those who understand that the physical world is only a shadow of the truth, and the sun that is glaring the eyes of the prisoners represents the higher truth of ideas. The light further represents wisdom, as even the paltry light that makes it into the cave allows the prisoners to know shapes.

Themes in the allegory appearing elsewhere in Plato's work[edit]

The allegory is probably related to Plato's theory of Forms, according to which the "Forms" (or "Ideas"), and not the material world known to us through sensation, possess the highest and most fundamental kind of reality. Only knowledge of the Forms constitutes real knowledge or what Socrates considers "the good".[6] Socrates informs Glaucon that the most excellent people must follow the highest of all studies, which is to behold the Good. Those who have ascended to this highest level, however, must not remain there but must return to the cave and dwell with the prisoners, sharing in their labors and honors.
Plato's Phaedo contains similar imagery to that of the allegory of the Cave; a philosopher recognizes that before philosophy, his soul was "a veritable prisoner fast bound within his body... and that instead of investigating reality of itself and in itself is compelled to peer through the bars of a prison."[7]

Scholarly discussion[edit]

Scholars debate the possible interpretations of the allegory of the Cave, either looking at it from an epistemological standpoint – one based on the study of how Plato believes we come to know things – or through a political (Politeia) lens.[6] Much of the scholarship on the allegory falls between these two perspectives, with some completely independent of either. The epistemological view and the political view, fathered by Richard Lewis Nettleship and A.S. Ferguson respectively, tend to be discussed most frequently.[6] Nettleship interprets the allegory of the cave as representative of our innate intellectual incapacity, in order to contrast our lesser understanding with that of the philosopher, as well as an allegory about people who are unable or unwilling to seek truth and wisdom.[8] Ferguson, on the other hand, bases his interpretation of the allegory on the claim that the cave is an allegory of human nature and that it symbolizes the opposition between the philosopher and the corruption of the prevailing political condition.[7][8]
Cleavages have emerged within these respective camps of thought, however. Much of the modern scholarly debate surrounding the allegory has emerged from Martin Heidegger's exploration of the allegory, and philosophy as a whole, through the lens of human freedom in his book The Essence of Human Freedom: An Introduction to Philosophy and The Essence of Truth: On Plato's Cave Allegory and Theaetetus.[9] In response, Hannah Arendt, an advocate of the political interpretation of the allegory, suggests that through the allegory, Plato "wanted to apply his own theory of ideas to politics".[10] Conversely, Heidegger argues that the essence of truth is a way of being and not an object.[11] Arendt criticised Heidegger's interpretation of the allegory, writing that "Heidegger…is off base in using the cave simile to interpret and 'criticize' Plato's theory of ideas".[10]

Various Scholars also debate the possibility of a connection between the work in the allegory and the cave and the work done by Plato considering the Analogy of the divided line and the Analogy of the Sun. The Divided Line is a theory presented to us in Plato's work the Republic. This is displayed through a dialogue given between Socrates and Glaucon. In which they explore the possibility of a visible and intelligible world. with the visible world consisting of items such as shadows and reflections (displayed as AB) then elevating to the physical item itself (displayed as BC) while the intelligible world consists of mathematical reasoning (displayed by CD) and philosophical understanding (displayed by DE).[12] Many seeing this as an explanation to the way in which the prisoner in the Allegory of the cave goes through the journey. First in the visible word with shadows such as those on the wall. Socrates suggests that the shadows are reality for the prisoners because they have never seen anything else; they do not realize that what they see are shadows of objects in front of a fire, much less that these objects are inspired by real things outside the cave which they do not see [12] then the realization of the physical with the understanding of concepts such as the tree being separate from its shadow. It enters the intelligible world as the prisoner looks at the sun. Leading to the Analogy of the Sun.[13]
The Divided Line – (AC) is generally taken as representing the visible world and (CE) as representing the intelligible world.[14]
The Analogy of the Sun refers to the moment in book six in which Socrates after being urged by Glaucon to define goodness purposes instead, an analogy through a "child of goodness". Socrates reveals this "child of goodness" to be the sun, proposing that just as the sun illuminates, bestowing the ability to see and be seen by the eye,[15]:169 with its light so the idea of goodness illumines the intelligible with truth. Leading some scholars to believe this forms a connection of the sun and the intelligible world within the realm of the allegory of the cave.
