Here the great art lies, to discern in what the law is to be to restraint and punishment, and in what things persuasion only is to work.
John MiltonAristotle ... imputed this symphony of the heavens ... this music of the spheres to Pythagorus. ... But Pythagoras alone of mortals is said to have heard this harmony ... If our hearts were as pure, as chaste, as snowy as Pythagoras' was, our ears would resound and be filled with that supremely lovely music of the wheeling stars.
John Milton
