"Yes, and quite irrespective of the opinion of the one who takes it. His thinking it water will not check or change its action in the slightest degree."
"But how does it kill?" persisted Clarke. "What does it do?"
"If you mean why, at the last analysis, does one drug attack cells and the other nourish them, I answer, frankly, I don't know--nobody knows."
Clarke pursued his point. "Under the microscope, the germ of, say, tetanus is a minute bar with spore at the end like the head of a tadpole. Of what is this cell composed?"
"Probably of a jelly-like substance with excessively minute filaments, but we don't know. We are at the limit of the microscope. We trace certain processes, we even dissect certain cells, but elemental composition of plasm remains a mystery."
The preacher glowed with triumph. "Then you confess yourself baffled? The union of matter and spirit is beyond your microscope. What do you know about a drop of water? You say it is formed of hydrogen and oxygen in such and such proportions. What is hydrogen? Why do they unite?"
"I don't know," calmly replied Serviss. "We admit that any material substance remains inexplicable. The molecule lies far below the line of visibility. We only push the zone of the known a little farther into the realm of the unknown; but how does that serve your argument?"
"By demonstrating that the mind of a man is simply the mastering mystery in a world of mysteries, and that there is no known limit to what it may do. We say that at the point where life enters to differentiate the germ is beyond science--there of necessity faith is born."
"You say 'we'--are you an apostle of 'the new church'?" asked Serviss, abruptly.
The preacher visibly shrank. "I do not care to announce my growing conviction to my congregation, at present; but I find many things about the doctrine which appeal to me. Some form of spiritism is the coming religion--in my judgment. The old order changeth. The traditional theology--the very faith I preach--has become too gross, too materialistic, for this age; some sweeter and more mystic faith is to follow. Even science is prophesying new power for man, new realms for the spirit. You men of science pretend to lead, but you are laggards. You pore upon the culture of germs, but shut your eyes to the most vital of all truths. Is the life beyond the grave of less account than the habits of animalculæ?"
The young scientist listened to this query with outward courtesy, but inwardly his gorge rose. "I see one gain in your new position," he answered, lightly. "Matter is no longer the dead, inorganic, 'godless thing' which the old-time theologians declared it to be. Matter, so far from being some inert lump, is permeated with life--is life itself. So far as we now know, all the visible and tangible universe is resolvable into terms of force--that is to say, chemical process. There may be no line of demarcation between the organic and the inorganic."
