If we admitted arbitrary claims at all, then we would be logically compelled to admit the possibility of alien mind control as well—and thus to abandon any knowledge of reality. Such claims would therefore violate our axiomatic understanding that "something exists" and "something is conscious of that existence" (p. 1.2:5). The arbitrary, in short, undercuts all knowledge and cannot be part of a fully integrated understanding of reality.

Because conceptual consciousness is naturally subject to error (p. 1.3:9), the notion that the arbitrary is "possible" may retain a superficial plausibility (despite the above refutation). In order fully to grasp the confusion underlying this notion, let us now explore the concepts of "truth" and "possibility" in further depth.

AGNOSTIC:	Yes. In fact, if I grant the possibility of your gremlins, I must grant the possibility of other unknown existents as well. Otherwise, I would be logically inconsistent. Logically, they all have just as much claim to the status of "possible existence."
MYSTIC B:	So do you know of any evidence one way or the other as to the existence of aliens who control your mind?
