In fact, he believes that religious beliefs and experiences have the capacity to be authoritarian and to control people's lives completely, making individuals live, completely for that. Many people see this as something evil and that must be combated, but it is not true. For James, if a person lives well and happily, within that authoritarian system of religious belief, that person must be left alone and must continue to live in the way that pleases him.
