“If,” says Professor Allman, “we were to admit that every living cell were a conscious and thinking thing, are we therefore justified in asserting that its consciousness with its irritability is a property of the matter of which it is composed? The sole argument on which this view is made to rest is analogy. It is argued that because the life phenomena, which are invariably found in the cell, must be regarded as a property of the cell, the phenomena of consciousness by which they are accompanied must also be so regarded. The weak point in the argument is the absence of all analogy between the things compared: and as the conclusion rests solely on the argument from analogy, the two must fall to the ground together.”
Try and assign to matter all the properties you can think of, its impenetrability, extension, weight, inertia, elasticity, and so forth, by no process of thought (as Mr. Justice Fry observes in an article in “The Contemporary Review [1]”) can you get out of them an adequate account of the phenomena of mind or spirit. We just now observed that consciousness, thought, and so forth, are never exhibited apart from the action of the brain; some change in the brain accompanies them all. We do not deny that. But it is obvious that thought being manifested in the presence of cerebral matter or something like it, is a very different thing from thought being a property of such matter, in the sense in which polarity is the property of a magnet, or irritability of living protoplasm.

To all this I have seen no answer. The way in which the opponents of Christian beliefs meet such considerations appears to be to ignore or minimize them, so as to pass over to what seems to them a satisfactory if not an easy series of transitions. If Life is after all only a “property” of matter, then given life, a brain may be produced; and as mind is always manifested in the presence of (and apparently indissolubly united with) brain structure, it is not a much greater leap to accept life as a property of matter than it is to take thought as a property of a certain specialized physical structure. It is true that the distance is great between the instinct of an animal and the abstract reasoning power of a Newton or a Herbert Spencer; but (as we are so often told) the difference is of degree not of kind, and as the brain structure develops, so does the power and degree of reason. As to the difference in man, that he is the only “religious” animal—the one creature that has the idea of God—that is a mere development of the emotions in connection with abstract reasoning as to the cause of things. No part of our mental nature is more common to the animal and the man than the emotional; and if in the one it is mere love and hatred, joy and grief, confidence and fear, in the other the emotions are developed into the poetic sense of beauty, or the awe felt for what is grand and noble; and this insensibly passes into worship, the root of the whole being fear of the unknown and the mysterious. That is the general line of argument taken up.
