“
The most competent physician of our world advises the patient to listen to an ignorant doctor who the patient thinks is very competent rather than to a competent doctor who the patient thinks is ignorant. He reason is that our imagination works for our good health, and as long as it is supplemented by remedies, it is capable of healing us. But the most powerful remedies are too weak when the imagination does not apply them.
