Do you know how many people come here looking for analyses of Synecdoche, New York?
LOTS, is how many.
This one is for you folks. Jordan Siron points us to his "Exploring Charlie Kaufman’s “Synecdoche, New York”: A Philosophical Analysis." It's a meaty read.
Synecdoche, New York is a film that concerns itself with examining solipsism, and in disposing of the harmful concept of “The Other”. Solipsism is the belief that only one’s own mind is certain to exist; that one’s perception of reality and events is the only certainty, the only truth. As a philosophy, it is akin to Objectivism — the belief that the pursuit of one’s own self interest is the only moral obligation to which any human is bound.
Solipsism is a gross philosophy. It does not leave room for the understanding or concern of others. It is diametrically opposed to Altruism, which — while impractical to some extent — at least gives us something worthy to strive for. While one can argue against the practicality of Altruism, it’s hard to rationalize Objectivism and Solipsism as being inherently healthy life philosophies. While they may serve the individual, they do not foster the wellbeing of the human community writ large.
Now, all of that isn’t to say that individuals who prescribe to philosophies that place themselves at the center of their own universe are inherently bad. One can argue that such philosophies drive individuals towards great personal success, and through that success said individuals can turn around and provide aid of which they might not have otherwise been capable. There is a certain benefit to being concerned with one’s own self, but this dissection is not concerned with those few individuals who put their own universes in check before extending their helping hand. So it follows that Synecdoche, New York does not concern itself with such.
The film examines solipsism at its worst, demonstrating the dangers of such a philosophy through its chosen vehicle: Caden Cotard. (Source)
