to keep bodily heat down when the outside temperature is 50 or even 80 degrees above that of the body?  Physiologists have not explained this, although assuredly an explanation is wanted.  But the true explanation, the correct explanation, would have demolished the doctrine that bodily heat is due to the food, and so it has not been given.  It is too simple to imagine that the bodily heat is, like the body itself and all its functions, the effect of the life-force that inhabits the body and builds up the body so that the body shall be a fit dwelling-place for itself—­this explanation is too simple and too idealistic for modern science, which is less and less disposed, we are told, to invoke the aid of a force of life to account for vital phenomena, although it assumes an attracting force to account for gravitating phenomena, and an electric and chemic force to account for electric and chemic phenomena.  Modern science (and ancient science, too, apparently) which sees well enough that an idealistic or a materialistic explanation would equally account for the nexus of the phenomena of the universe, deliberately and almost invariably prefers the materialistic explanation.  She is anxious that we should be kept free of superstition.  But the superstition that forces are the effects of things does not seem to distress her at all.  And so we are told that gravitation is a property of matter, and are forbidden to think that perhaps gravitation, a force, procreates matter, a thing, in order that the effects of the fore may be perceived by dull sense.  We are told that the function of the liver and the brain depends on the structure of the liver and the brain respectively and we are not allowed to think that perhaps the force of animal life, feeling the need of an instrument to secrete bile, on the one hand, and to secrete cerebral lymph to act as a vehicle for the conveyance of thought and emotion and higher things, on the other, introduces the liver with its elaborate structure and the brain with its still more complicated structure, in order that both the one function and the other may be well performed.  And so, although all forms of kinetic energy (and among them zoo-dynamic, or the force of animal life) manifest warmth and luminosity as qualities, science attributes animal heat to chemic force and refuses to consider that perhaps zoo-dynamic uses chemico-dynamic for its own purposes, even if these purposes are unconscious, because the higher force always dominates the lower.  Properly speaking, science is out of her sphere, though she does not seem to know it, in making these suggestions.  When she keeps herself to the investigation of facts, their exposition, their sequence and their laws, in her painstaking and accurate manner, we accept her revelations thankfully, and beg her to allow us to make our own philosophic and other explanations in attempting to account for the existence, sequences and relations of the facts of life.
