Reactive mind

The reactive mind is a concept in the Scientology religion formulated by L. Ron Hubbard, referring to that portion of the human mind that is unconscious and operates on stimulus-response, to which Hubbard attributed most mental, emotional, and psychosomatic ailments:

"What can it do? It can give a man arthritis, bursitis, asthma, allergies, sinusitis, coronary trouble, high blood pressure and so on, down the whole catalog of psychosomatic ills, adding a few more which were never specifically classified as psychosomatic, such as the common cold." - L. Ron Hubbard (, 1999 paperback edition, pg.69)
