Coleridge, Biographia Literaria, Ch. 8: But how any affection from without can metamorphose itself into perception or will; the materialist has hitherto left, not only as incomprehensible as he found it, but has aggravated it into an incomprehensible absurdity. For, grant that an object from without could act upon the conscious self, as on a consubstantial object; yet such an affection could only engender something homogeneous with itself. Motion could only propagate motion. Matter has no inward. We remove one surface, but to meet with another. We can but divide a particle into particles; each atom comprehends in itself the properties of the material universe. Let any reflecting mind make the experiment of explaining to itself the evidence of our sensuous intuitions, from the hypothesis that in any given perception there is a something which has been communicated to it by an impact or an impression ab extra. In the first place, by the impact on the percipient or ens representans not the object itself, but only its action or effect, will pass into the same. Not the iron tongue, but its vibrations, pass into the metal of the bell. Now in our immediate perception, it is not the mere power or act of the object, but the object itself, which is immediately present. We might indeed attempt to explain this result by a chain of deductions and conclusions; but that, first, the very faculty of deducing and concluding would equally demand an explanation; and secondly, that there exists in fact no such intermediation by logical notions, such as those of cause and effect. It is the object itself, not the product of a syllogism, whish is present in our consciousness. Or would we explain this supervention of the object to the sensation, by a productive faculty set in motion by an impulse; still the transition, into the percipient, of the object itself, from which the impulse proceeded, assumes a power that can permeate and possess the whole soul, As like a God by spiritual art, Be all in all, and all in every part. CROWLEY And how came the percipient here? And what is become of the wonder-promising matter, what was to perform all these marvels by force of mere figure, weight, and motion? The most consistent proceeding of the dogmatic materialist is to fall back into the common rank of soul-and-bodyists; to affect the mysterious, and declare the whole process a revelation given, and not to be understood, which it would profane to examine too closely. Datur non intelligitur. But a revelation unconfirmed by miracles, and a faith not commanded by the conscience, a philosopher may venture to pass by, without suspecting himself of any irreligious tendency. Thus as materialism has been generally taught, it is utterly unintelligible, and owes all its prodelytes to the propensity so common among men, to mistake distinct images for clear conceptions; and vice versa, to reject as inconceivable whatever from its own nature is unimaginable.
