    “The atoms of Democritus
    And Newton’s particles of light
    Are sands upon the Red Sea shore,
    Where Israel’s tents do shine so bright.”
    —William Blake (1757–1827)

    “Shy and proud men ... are more liable than any others to fall into the hands of parasites and creatures of low character. For in the intimacies which are formed by shy men, they do not choose, but are chosen.”
