Paranoia is defined as "an excessive axiety or fear".

http://en.wikipedia.org/wiki/Paranoia

However, the mind must be willing to reason through it and only then does it seem tangible, as reasoning gives way to abstract tangibility to thought itself. Concepts are subconscious analogies and models made tangible by reason and presented to the conscious. It would only make sense. Why do we experience fear and anxiety, or better yet, why do we allow and rationalize it? (rationalization is the enemy of reason).

(Hey so I thought I'd get a few more posts in. So what?)

What?! What are you saying to me? How can you say that I'm so angry, I don't know how you've been able to follow me all this time, I am gonna find you I swear it! OMG someones watching me, help, help... stop watching me... no! :( Nooooooooooo

Strange that you opened the post with a definition of paranoia, the EXCESSIVE fear, then went on to talk about plain, regular, ol', normal fear. The two ain't even close to being in the same ballpark, much less to discuss in a forum such as this.

Fear is a natural, human emotion that helps us to remain alive and well and functioning in various enviroments of life. I.e, you don't go walking around in the worse parts of town with $100 bills hanging out of your pockets.

Now, as to the paranoia, that's excessive, unreasoned, irrational fear. See? Those are two entirely different things.
