The most beautiful and most profound emotion we can experience is the sensation of the mystical. It is the sower of all true science. He to whom this emotion is a stranger, who can no longer wonder and stand rapt in awe, is as good as dead. To know what is impenetrable to us really exists, manifesting itself, as the highest wisdom and the most radiatn beauty which our dull faculties can comprehend only in the most primitive form -- this knowledge, this feeling is at the centre of true religiousness.
the cosmic religious experience is the strongest and oldest mainspring of scientific research. My religion consists of a humble admiration of the illimitable superior spirit who reveals himself in the slight details we are able to perceive with our frail and feeble minds. That deeply emotional conviction of the presence of a superior reasoning power, which is revealed in the incomprehensible universe, forms my idea of God.
