For example, «If I recite a, b, c, d, e, f, g, at the moment of uttering d, neither a, b, c, nor e, f, g, are
out of my consciousness altogether, but both, after their respective fashions, «mix their dim lights» with the stronger one of d...» (PP1 257).
But in the production
of consciousness by the brain, the terms are heterogeneous natures
altogether; and as far as our understanding goes, it is as great a miracle as if we said, Thought is «spontaneously generated,» or «created
out of nothing.»
