MY THEORY: the trouble is in the mind, for the body is only the house for the mind to dwell in . . . If your mind has been deceived by some invisible enemy into a belief, you have put it into the form of a disease, with or without your knowledge. By my theory or truth I come in contact with your enemy and restore you to health and happiness.
Phineas QuimbyThe doctors take the bodily evidence as the disease. . . . disease is itself an impudent opinion. He throws off the feelings of the sick and imparts to them his own which are perfect health, and his explanation destroys their feelings or disease. . . . He is like a captain who knows his business and feels confident in a storm, and his confidence sustains the crew and ship when both would be lost if the captain should give way to his fears.
