(Finishing off in a second comment; this was too long for one!)
It is mainly the difference between the map and the territory, that marks the difference between objective and subjective reality.
That comma makes my teeth itch.
The map, or how we perceive the territory, does not necessarily reflect the territory (reality) itself.
OK, this is better. Maybe this is the unpacking I was looking for after all. Still feels like it could take more explanatory work. Maybe you could even put this part a lot nearer the start of the essay, because it's helping you get a bit closer to explaining what you might mean by "reality", too. You've been keeping that very quiet up to now.
One can have directions on a map that appear to lead to somewhere quite interesting, but when acted out within the territory, can be misleading.
I like the concept you're trying to get across here. I think this sentence could be improved a lot. "Somewhere quite interesting" is lame. Great opportunity to pick an awesome example! "Acted out" doesn't seem right. Directions are things that you follow. Instead of "can be misleading", pick an awful kind of place you could end up in by accident.
Changing a belief about something changes nothing but chemical firing patterns within the brain.
OK, this is the first we've really heard about the brain as opposed to the mind. Potentially a useful approach, but it comes out of left field a bit. Can you explain that you're about to start talking about neuroscience before doing so, maybe?
The goal should be to attempt to draw maps as close as possible to the actual territory, but to do so, human fallibility must be admitted, and an attitude of humility should be taken up.
Wait, now we're back with the maps analogy. The neuroscience bit went nowhere and didn't seem to further your maps point either. What was the deal with that...?
"The goal" depends on what we're trying to achieve. You haven't specified that.
"An attitude of humility should be taken up" is awkward. Chuck it out and rewrite, I think.
I hope some of that advice was useful! Even if you disagree with all my criticisms and don't like any of my suggestions, perhaps I've demonstrated something useful about fine-toothed-comb editing. It can really benefit your writing a lot. Just inspect each sentence closely in turn and find ways to improve it. There will almost always be ways! That's before you even get as far as examining your structure at the paragraph level...
Good luck with improving your writing.
PS. The fact that I've been critiquing your writing means my own will have been riddled with horrible errors in these comments. I just fixed one instance - I have no doubt there are others. Sorry about that.
I want to start out by saying that I'm an ultra-beginner when it comes to stuff like this, but I had to do a definition essay in English, and I chose to contrast objective and subjective reality. So, if any of this seems wrong to you, please let me know. I'm sort of stuck right now, because I'm not really sure what to write about next. I'm thinking maybe the history of how the terms came to be or something. Also, for citations, I'm struggling with MLA formatting, so I might not have something in quotations cited, let me know if you want the cites for something.
Regardless of whether or not one watches a phenomenon occur, it still, in fact, occurs. Or does it? This argument is known as objective versus subjective reality. While objective reality initially seems to be the more obvious and substantial answer, fairly recent discoveries in the world of quantum physics have caused new questions to spring up regarding this ancient belief. Whether or not reality occurs outside of the human mind or exists only inside of the consciousness is a question that, despite countless arguments, remains unresolved. Despite arguments that insist on promoting the idea that reality is entirely dependent on our fallible perceptions (subjective reality), the evidence remains in favor that there is indeed a real world that exists independent of our observations (objective reality).
Subjective reality is defined as “relating to or of the nature of an object as it is known in the mind as distinct from a thing in itself.” Proponents of this theory generally believe that reality is relative, and so if someone cannot see an object in front of them, it ceases to exist. Objective reality, in contrast, means “existing independent of thought or an observer as part of reality.” Objective reality usually implies that everything can be proven using rationality, science, and mathematics. Although people use their mind to interpret and to put into practice this information, it still exists outside of the mind to be observed.
If there existed a picture, in a room, two people could agree that the picture is objective, and occurs outside of their mind. However, one could find the picture to be quite lovely, and another could detest it with a passion. These two ideas are not necessarily wrong, but are subjective. Based on this thought, some would suggest that reality is merely whatever a person believes reality to be. However, “Reality is that which, when you stop believing in it, doesn’t go away” (Dick). Someone can choose to deny the existence of gravity, but when they step off of a building, the end result is fairly obvious. Simply thinking something to be true does not make it so, because “the map is not the territory” (Korzybski, par.1).

Note: This is all I have so far, I'm supposed to be about halfway done. Anything that is incorrect/needs fixing? :D Thanks guys!
