Beauty is eternity gazing at itself in a mirror.
Whereas the beautiful is limited, the sublime is limitless, so that the mind in the presence of the sublime, attempting to imagine what it cannot, has pain in the failure but pleasure in contemplating the immensity of the attempt.
When you do something noble and beautiful and nobody noticed, do not be sad. For the sun every morning is a beautiful spectacle and yet most of the audience still sleeps.
