What is a Clear?

So, what is Clear? Hubbard defines Clear in Dianetics: the Modern Science of Mental Health as a person who no longer has a Reactive Mind or has achieved the realization (or as Scientologist call it cog or cognition) that they mocked up their reactive mind. In the beginning Hubbard was more outspoken and outlandish with his claims stating that a Clear would be completely free of any psychosomatic illnesses, have a vastly increased intelligence, a near perfect memory, complete control over his or her bodily functions, have perfect eyesight, and would never catch a cold or become ill in any way.
