"Some Native people suggest that one should test how cold the hands are by touching the thumb to the little finger of the same hand. As soon as you cannot carry out this exercise you are reaching a dangerous state of incapacity and you should immediately take steps to warm up."

The sick individual finds himself at home with all other similarly sick individuals. The whole culture is geared to this kind of pathology. The result is that the average individual does not experience the separateness and isolation the fully schizophrenic person feels. He feels at ease among those who suffer from the same deformation; in fact, it is the fully sane person who feels isolated in the insane society - and he may suffer so much from the incapacity to communicate that it is he who may become psychotic.
