Philosophy would not be worthwhile if it did not take the view that for the practical purposes of life, it must turn around and adopt a non-metaphysical approach. Thus a twofold attitude is the only complete and therefore correct one which it may approve. We have the right and bear the duty to ask ourselves in what way is a teaching related to everyday living; in what way is it connected with the world we know? If both relation and connection are absent, it is fair to say that the teaching is inadequate and lacks the necessary balance of interests.
