Thomas Szasz
If you talk to God, you are praying. If God talks to you, you have schizophrenia.
Formerly, when religion was strong and science weak, men mistook magic for medicine; now, when science is strong and religion weak, men mistake medicine for magic.
Happiness is an imaginary condition, formerly attributed by the living to the dead, now usually attributed by adults to children, and by children to adults.
If you talk to God, you are praying; if God talks to you, you have schizophrenia.
