ic and molecular movements required
for the thinking of a single man would be beyond the capacity of all the
gods of the supernaturalistic interpretations of religion together.
Some idea of the number of such motions which are taking place in every
human brain, will be derived from the conservative representations of
Hofmeister as exhibited in the following condensed form by McCabe in his
book, "The Evolution of Mind:"
We have reason to believe that there are in each molecule of
ordinary protoplasm at least 450 atoms of carbon, 720 atoms of
hydrogen, 116 of nitrogen, 6 of sulphur, and 140 of oxygen.
Nerve-plasm is still more complex.
Recent discoveries have only increased the wonder and potentiality
of the cortex. Each atom has proved to be a remarkable
constellation of electrons, a colossal reservoir of energy. The
atom of hydrogen contains about 1,000 electrons, the atom of carbon
12,000, the atom of nitrogen 14,000, the atom of oxygen 16,000, and
the atom of sulphur 32,000. These electrons circulate within the
infinitesimal space of the atom at a speed of from 10,000 to 90,000
miles a second. It would take 340,000 barrels of powder to impart
to a bullet the speed with which some of these particles dart out
of their groups. A gramme of hydrogen--a very tiny portion of the
simplest gas--contains energy enough to lift a million tons more
than a hundred yards.
Of these astounding arsenals of energy, the atoms, we have, on the
lowest computation, at least 600 million billion in the cortex of
the human brain.
Scientists, says Professor Olerich, in his book, "A Modern Look at
the Universe," estimate that the chemical atom is so
infinitesimally small that it requires a group of not less than a
billion to make the group barely visible under the most powerful
microscope, and a thousand such groups would have to be put
together in order to make it just visible to the naked eye as a
mere speck floating in the sunbeam.
The microscope reveals innumerable animalcules in the hundredth
part of a drop of water. They all eat, digest, move and from all
appearances of their frolics, they are endowed with sensation and
ability of enjoyment. What then shall we say of the minuteness of
the food they eat; of the blood that surges through their veins; of
their nervous syst
