Last time, I alluded, in a footnote, to an “elsewhere” wherein William Blake clarifies his mind/body dualism position.  I have since been cadged by the masses into both clarifying myself and citing my sources.  This quote comes from The Marriage of Heaven and Hell, plate IV (which I linked to in my previous post, before getting into the guts of the interpretation):

All Bibles or sacred codes have been the causes of the following Errors.

1. That Man has two real existing principles Viz: a Body & a Soul.

2. That Energy, call’d Evil, is alone from the Body, & that Reason, call’d Good, is alone from the Soul.

3. That God will torment Man in Eternity for following his Energies.

But the following Contraries to these are True

1. Man has no Body distinct from his Soul for that call’d Body is a portion of Soul discern’d by the five Senses, the chief inlets of Soul in this age.

2. Energy is the only life and is from the Body and Reason is the bound or outward circumference of Energy.

3. Energy is Eternal Delight.

You can find the full text of the work here.  I think Blake’s position here augments my previous discussion without much need for further explanation and analysis
