“But who can believe that such a faculty, so divine, so godlike and spiritual, can be the mere result of organization? That any juxta-position of _material_ molecules, of whatsoever nature, from whatever source derived, in whatever order and forms arranged, and wherever placed, could generate thought, and reflection, and reasoning powers, could acquire and store up ideas and notions, as well concerning metaphysical as physical essences, may as safely be pronounced impossible, as that matter and spirit should be homogeneous. Though the intellectual part acts by the brain and nerves, yet the brain and nerves, however ample, however developed, are not the intellect, nor an intellectual substance, but only its instrument, fitted for the passage of the prime messenger of the soul, its nervous fluid or power to every motive organ. It is a substance calculated to convey instantaneously that subtile agent, by which spirit can act upon body, wherever the soul bids it to go and enables it to act. When death separates the intellectual and the spiritual from the material part, the introduction of a fluid, homogeneous with the nervous, or related to it by a galvanic battery, can put the nerves in action, lift the eyelids, move the limbs; but though the action of the intellectual part may thus be imitated, in newly deceased persons, still there are no signs of returning intelligence, there is no life, no voluntary action, not a trace of the spiritual agent that has been summoned from its dwelling. Whence it follows, that though the organization is that by which the intellectual and governing power manifests its presence and habitation, still it is evidently something distinct from and independent of it[13].”
