Every event which might claim to be a miracle is, in the last resort, something presented to our senses, something seen, heard, touched, smelled or tasted. And our senses are not infallible. If anything extraordinary seems to have happened, we can always say that we have been victims of an illusion. If we hold a philosophy which excludes the supernatural, this is what we shall say. What we learn from experience depends on the kind of philosophy we bring to experience. It is therefore useless to appeal to experience before we have settled, as well as we can, the philosophical question.
