It is out of such a splendid balance of utter humility and noble self-reliance that the philosopher gets his wisdom and strength. He is always kneeling metaphorically before the Divine in self-surrendering renunciation and often actually in self-abasing prayer. Yet side by side with this, he is always seeking to develop and apply his own intellect and intuition, his own will and experience in life. And because they are derived from such a balanced combination, this wisdom and strength are beyond any that religion alone, or metaphysics alone, could give.
