"The most beautiful experience we can have is the mysterious. It is the
fundamental emotion which stands at the cradle of true art and true science.
Whoever does not know it and can no longer wonder, no longer marvel, is as
good as dead, and his eyes are dimmed. It was the experience of mystery--
even if mixed with fear -- that engendered religion. A knowledge of the
existence of something we cannot penetrate, our perceptions of the profoundest
reason and the most radiant beauty, which only in their most primitive forms
are accessible to our minds -- it is this knowledge and this emotion that
constitute true religiosity; in this sense, and in this alone, I am a
deeply religious man."
[Albert Einstein,_The World as I See It_]
