Is Scientology Scientific?

The following is a quote from "Dianetics: the Modern Science of Mental Health"
    "Clinical tests prove these statements to be scientific facts:

    1.  The mind records on some level continuously during the entire  
        life of the organism.
    2.  All recordings of the lifetime are available
    3.  "Unconsciousness," in which the mind is oblivious of its       
        surroundings, is possible only in death and does not exist as  
        total amnesia in life.
    4.  All mental and physical derangements of a psychic nature come  
        about from moments of "unconsciousness."
    5.  Such moments can be reached and drained of charge(harmful      
       energy or force accumulated and stored in the reactive mind,    
       resulting from the conflicts and unpleasant experiences that a  
       person had) with the result of returning the mind to optimum    
       operating condition.

If you are in a discussion with a scientologist, you might like to ask which clinical tests prove the above statements, who did them and where they were published. In the experience of many critics, scientologists are unable or unwilling to give this essential information.

Jeff Jacobsen has written several articles on the scientific status of L Ron Hubbard's teachings. Science and Dianetics challenges assertions like the above. The origins of Dianetics are looked at in Dianetics: From Out of the Blue?
