the heart of a man

“Deep, deep, and still deep and deeper must we go, if we would find out the heart of a man; descending into which is as descending a spiral stair in a shaft, wthout any end, and where that endlessness is only concealed by the spiralness of the stair, and blackness of the shaft.”

—Herman Melville, Pierre: or, The Ambiguities, 1852.
