Mock On, Mock On

Mock on, mock on, Voltaire, Rousseau;
Mock on, mock on, ’Tis all in vain.
You throw the sand against the wind,
And the wind blows it back again.

And every sand becomes a Gem
Reflected in the beams divine;
Blown back, they blind the mocking
Eye,
But still in Israel’s paths they shine.

– William Blake
