"The word that most needs definition is reality. After all what is more firm or grounded than the very thing which is constant, reality. The concept of a breaking reality or questioning all that makes reality is a shocking revelation. That is why it is so important to define, because if we do not then we risk culture shock when our reality is torn down.
The best place to start would be where does reality end. There is a very simple test to do in order to determine if something is real. To begin this test thing of one thing that is being questioned. Is the possibility of that thing occurring constant, if it is not then it is not reality, it is an ephemeral shadow designed to detract from reality. These are things like ghosts, which may exist; however, we can not define them under the same context of reality. War is reality, immortality is not.
Reality also encompasses the senses absolutely. There is no median between sense and reality they are rather two sides of the same truth. When one ends the other begins forever in an endless cycle. Reality is also an interpretation of what is real. There is not exact science to the art of perceiving there is only what we believe there to be. All things are constantly trying to deceive you, and not surprisingly they are doing a very good job of it. God's greatest joke on man by far was giving him consciousness to know what being happy was like, and then never giving the feeling depth to last. Reality is constantly forcing you to change homeostasis is impossible as long as reality bends the reins. Sure making X amount of money for Y amount of time is fine, until Y reaches a long standing state of homeostasis. Then the transition between perceived comfort and actual comfort is breached. Congratulations, perception just won out again.
Reality is often a big picture, it seldom sits beside and allows fantasy to play out against the common. It is so little that fantasy takes hold that some associate it with children or the insane. Good job reality, you've turned us against ourselves.
Reality is not so much an enemy, faceted ground on which you stand. Without it concepts seem disjointed, loose.
The two paragraphs above don't exist. Do they exist? Reality seems to say yes, but perhaps the answer is to extend reality to realize our reality is limited to what we believe it to be. The whole point of this," Desmond said to Sedaris, "is that maybe we're just some Deus Ex Machina thought of in some last minute blog assignment." Sedaris turned to face Desmond and spoke quietly, "This is not a sentence."
