Consider once more the basic concepts of Evolution. They are two in number, 1. Potentially, the feather of the blue-bird was in the speck of original protoplasm, potentially the flights of Dante's and Goethe's genius were in the primordial cell. All that has occurred in history has developed out of antecedents. Furthermore: 2. All that exists has developed according to natural laws.
However, it is a curious fact that life is connected with a cellular structure called protoplasm, or in English, "first stuck together;" whence, conceivably through deuteroplasms, or second stickings, and tritoplasms, or third stickings,* we reach the highest plastic phase in the human pottery, which differs from common chinaware, primarily, by a measurable degree of heat, developed in breathing, which it borrows from the rest of the universe while it lives, and which it as certainly returns to the rest of the universe, when it dies.
Without their spirit life might never have moved out of protoplasm. More and more do I refuse to draw my income and sneer at those who guarantee it. There are times when it seems to me " "And to me, and to all women. So one kissed Paul." "That's brutal," said Margaret. "Mine is an absolutely different case. I've thought things out." "It makes no difference thinking things out.
In the lowest organism all parts are competent to perform all functions, and one and the same portion of protoplasm may successfully take on the function of feeding, moving, or reproducing apparatus.
The soft slimy plasson of the body of the moneron is generally called "protoplasm," and identified with the cellular matter of the ordinary plant and animal cells. But we must, to be accurate, distinguish between the plasson of the cytodes and the protoplasm of the cells. This distinction is of the utmost importance for the purposes of evolution.
We must turn now to the problem connected with protoplasm and the living cell, since here, if anywhere, can we find the life substance reduced to its lowest terms. ==Vital Properties.== We have seen that the general activities of the body are intelligible according to chemical and mechanical laws, provided we can assume as their foundation the simple vital properties of living phenomena.
This we think was a very natural, if not an unavoidable mistake, on the part of the public. For in that Essay, he says that Protoplasm, or the physical basis of life, "is a kind of matter common to all living beings, that the powers or faculties of all kinds of living matter, diverse as they may be in degree, are substantially of the same kind."
He poured out his knowledge to me in the most unreserved manner, yet was strangely jealous on some points. I called on him two or three times before the voyage of the "Beagle", and on one occasion he asked me to look through a microscope and describe what I saw. This I did, and believe now that it was the marvellous currents of protoplasm in some vegetable cell.
The chasm between unconscious life and thought is deep and impassable, and no transitional phenomena are to be found by which, as by a bridge, we can span it over. There can be life or function without consciousness or thought; therefore, even if we go so far as to admit that life is only a property of protoplasm, there can be no ground for saying that thought is only a property of protoplasm.
The germ cell as has been established by the microscope is the tiny cell which in the lowest living organisms as well as in man himself, forms the unit of physical development. Yet even this tiny cell is already a highly organized and perfected thing. It is composed of the most widely differing elements which, taken together, form the so-called protoplasm or cellular substance.
