A creative, never heard before choice, I always think of is The Matrix, I know, This theory every single time never fails to remind me of the cinematic masterpiece that is The Matrix. A classic for sure, but I think this movie completely embodies this theory almost, I would argue, in its entirety. Now while the two quotes I have chosen to pull are quite close together in placement they are some of the most stand out scenes of the movie and most people even without watching the film in its entirety know these references or remember these pieces.
"This is your last chance. After this, there is no turning back. You take the blue pill - the story ends, you wake up in your bed and believe whatever you want to believe. You take the red pill - you stay in Wonderland and I show you how deep the rabbit hole goes." - Morpheus
After Morpheus saves Neo from the slime pod he is being held captive in, he tells Neo that is is in a completely undetectable mind prison, and that he has the option to choose a red pill, one of knowledge and which will allow him to see the worlds harsh truths, or the blue pill, the other that allows Neo to return to his comfortable ignorance and slavery.
This application of theory is to suggest that in this instance Morpheus acts as the cave entrance, but not something that person from the cave necessarily sought out, almost as if a line of fate was cast and after being prompted and knowing what the options are (without detail) he can choose. I like how it is something Neo knows up front, that he can choose something mind opening and new, and the alternative of not wanting to find out.
"The second quote to pull is "You have to let it all go, Neo - fear, doubt, and disbelief. Free your mind!" - Morpheus
Another Morpheus Quote but this is the after math choice of Neo choosing the [red] pill. When Morpheus is explaining to Neo that despite his perception, and within his allowance to want to be outside of "the cave" he is now to leap from one skyscraper from another without falling to his death. A seemingly impossible feat, however, this is a learning exercise. Neo is a free mind slave, no longer in control of the Matrix though there is still a long way ahead of him before he can now manipulate what he knows and how to use the Matrix to his own will. A test he will surely fail, but one that falls back to the cave piece. Here is is exemplified that is is not simply enough to agree to see that outside. But to be pushed, be made to understand, and to test things out. Much like Plato's theory, you cannot just leave the cave and that be the defining moment. You must learn, and change, and grow, to be challenged. Not a simple, and easy task but something to be challenged with, and being aware of these options, a luxury that the people of the theory do not have. Everyone I have ever known to hear and discuss this theory always agrees that they would be the one to leave. However, that would be a perfect world where in that example not a single person would be in the cave to begin with, and this is not a perfect world, so I really appreciate this scene and application of the theory, almost even more than the initial one.
