In the last Michael Kors outlet extract, the professor evidently prefers, of the two alternatives he suggests, the one that asserts that "the matter of life [protoplasm] is composed of ordinary matter, is built up of ordinary matter, and resolved again into ordinary matter when its work is done." This the professor applies to man as well as to plants and animals. Hence, he cites the Roman poet,
"Debemur morti nos nostraque."
But we have conceded the Michael Kors Handbags professor more than he asks. We have conceded that all matter is, in a certain sense, plastic, and living, in the sense of being active, not passive. But the professor does not ask so much. We inferred from some things in the beginning of his discourse that he intended to maintain that his protoplasm is itself elemental, and pervading all nature. But this is not thecase; he merely holds it to be a chemical compound formed by the peculiar chemical Michael Kors Watches combination of lifeless components. Thus he says:
"But it will be observed that the existence of the matter of life depends on the pre-existence of certain compounds, namely, carbonic acid, water, and ammonia. Withdraw any one of these three from the world, and all vital phenomena come to an end. They are related to the protoplasm of theplant, as the protoplasm of the plant is to that of the animal. Carbon, hydrogen, Michael Kors Shoes oxygen, and nitrogen are all lifeless bodies. Of these, carbon and oxygen unite in certain proportions and under certain conditions, to give rise to carbonic acid; hydrogen and oxygen produce water ; nitrogen and hydrogen give rise to ammonia. These new compounds, like the elementary bodies of which they are composed, are lifeless. But when they are brought together, under certain conditions they give rise to the still more complex body, protoplasm, and this protoplasm exhibits the phenomena of life. I see no break in this series of steps in my secular complication, and I am unable to understand why the language which is applicable to any one term of the series may not be used to any of the others."
But here is a break or a bold leap from a lifeless to a living compound. No matter how different Michael Kors are the several chemical compounds known from the simple components, the new compound is always, as far as known, as lifeless as were the several components themselves. Hydrogen and oxygen compounded give rise to water, but water is lifeless. Hydrogen and nitrogen, brought together in certain proportions, give rise to ammonia, still a lifeless compound. No chemist has yet, by any combination of the minerals, carbon, hydrogen, oxygen, and nitrogen, the constituents of protoplasm, been able to produce a juciy couture uk living plant or a living organism of any sort. How then conclude that their combination produces the matter of life, or gives rise to the living ,organism? There seems to us to be a great gulf between the premises and ithe conclusion. Certain combina•JRODS of carbon, hydrogen, oxygen, and nitrogen produce certain lifeless •compounds different from themselves, therefore a certain other combination of these same elements produces the living organism, plant, or animal, or originates the matter, and forms the physical basis of life. If the professor had in his school days reasoned
in this way, his logic-master, we suspect, would have set a black mark against his name, or, more likely, have rapped him over the knuckles, if not over his head, and told him that an argument that has no middle term, is no juciy couture tracksuits argument at all, and that" Transitio a genere ad genus," as from the lifeless to the living, is a sophism.
