    ‘Pure experience’ is the name I gave to the immediate flux of life which furnishes the material to our later reflection with its conceptual categories.

    the race is not to the swift, nor the battle to the strong, neither
    yet bread to the wise, nor yet riches to men of understanding, nor yet
    favour to men of skill; but time and chance happeneth to them all.
    Bible: Hebrew Ecclesiastes (l. IX, 11)

    Poor John Field!—I trust he does not read this, unless he will improve by it,—thinking to live by some derivative old-country mode in this primitive new country.... With his horizon all his own, yet he a poor man, born to be poor, with his inherited Irish poverty or poor life, his Adam’s grandmother and boggy ways, not to rise in this world, he nor his posterity, till their wading webbed bog-trotting feet get talaria to their heels.
    Henry David Thoreau (1817–1862)
