But the most common derivation of the present from a previous life is that which explains the descent as a punishment for sin. In that earlier and loftier state, souls abused their freedom, and were doomed to expiate their offences by a banished, imprisoned, and burdensome life on the earth. "The soul," Plutarch writes, "has removed, not from Athens to Sardis, or from Corinth to Lemnos, but from heaven to earth; and here, ill at ease, and troubled in this new and strange place, she hangs her head like a decaying plant." Hundreds of passages to the same purport might easily be cited from as many ancient writers. Sometimes this fall of souls from their original estate was represented as a simultaneous event: a part of the heavenly army, under an apostate leader, having rebelled, were defeated, and sentenced to a chained bodily life. Our whole race were transported at once from their native shores in the sky to the convict land of this world. Sometimes the descent was attributed to the fresh fault of each individual, and was thought to be constantly happening. A soul tainted with impure desire, drawn downwards by corrupt material gravitation, hovering over the fumes of matter, inhaling the effluvia of vice, grew infected with carnal longings and contagions, became fouled and clogged with gross vapors and steams, and finally fell into a body and pursued the life fitted to it below. A clear human child is a shining seraph from heaven sunk thus low. Men are degraded cherubim. "Our birth is but a sleep and a forgetting: The soul that rises with us, our life's star, Hath had elsewhere its setting, And cometh from afar."
