Staring into Shadows

Allegory of the Cave

While the focus up to this point was mostly on stars and ionized gas, it is also possible to look at dust in a new, more complete way. We use the resolving power of MUSE to measure the optical attenuation with a spectral resolution of 6.

Several sharp features are superimposed: No correlation was observed between sodium line strength and reddening by dust on spatially resolved scales. Additionally, the continuum attenuation was found to be independent from the Balmer decrement tracing ionized gas attenuation. We model and interpret the variations in the attenuation curves of each spatial resolution element of NGC We find that the amount and distribution of dust along the line of sight is highly degenerate with any variation in the intrinsic extinction law.

Our analysis shows that the interstellar matter in NGC resides in a regular and well-settled disc. Our results preach caution in the application of simple recipes to de-redden global galaxy spectra and underlines the need for more realistic dust geometries when constructing such correction formulas.

MUSE stares into the shadows: 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. Socrates remarks that this allegory can be paired with previous writings, namely the analogy of the sun and the analogy of the divided line.

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. Plato begins by having Socrates ask Glaucon to imagine a cave where people have been imprisoned 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 a—b. 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 c. 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 ba.

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. 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 a. 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; "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 c.

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 e.

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 a. The allegory contains many forms of symbolism used to describe the illusions of the world. The cave represents the superficial world for the prisoners. The chains that prevent the prisoners from leaving the cave represent ignorance, meaning the chains are stopping them from learning the truth.

The shadows that cast on the walls of the cave represent the superficial truth, which is an illusion that the prisoners see in the cave. The freed prisoner represents those in society who see the physical world for the illusion that it is. The sun that is glaring the eyes of the prisoners represents the real truth of the actual world.

Staring at the shadows on the wall

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".

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 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.

The epistemological view and the political view, fathered by Richard Lewis Nettleship and A.

Ferguson respectively, tend to be discussed most frequently. 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: On Plato's Cave Allegory and Theaetetus.
