The most beautiful emotion we can experience is the mystical. It is the power of all true art and 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 that what is impenetrable to us really exists, manifesting itself as the highest wisdom and the most radiant beauty, which our dull faculties can comprehend only in their most primitive forms - this knowledge, this feeling, is at the center of true religiousness. In this sense, and in this sense only, I belong to the rank of devoutly religious men.
Albert EinsteinPure logical thinking cannot yield us any knowledge of the empirical world. All knowledge of reality starts from experience and ends in it.
Albert EinsteinCompound interest is the eighth wonder of the world. He who understands it, earns it ... he who doesn't ... pays it.
