A LAW OF ACCELERATION (1904)
IMAGES are not arguments, rarely
even lead to proof, but the mind craves them, and,
of late more than ever, the keenest experimenters
find twenty images better than one, especially if
contradictory; since the human mind has already learned
to deal in contradictions.
The image needed here is that of
a new centre, or preponderating mass, artificially
introduced on earth in the midst of a system of attractive
forces that previously made their own equilibrium,
and constantly induced to accelerate its motion till
it shall establish a new equilibrium. A dynamic
theory would begin by assuming that all history, terrestrial
or cosmic, mechanical or intellectual, would be reducible
to this formula if we knew the facts.
For convenience, the most familiar
image should come first; and this is probably that
of the comet, or meteoric streams, like the Leonids
and Perseids; a complex of minute mechanical agencies,
reacting within and without, and guided by the sum
of forces attracting or deflecting it. Nothing
forbids one to assume that the man-meteorite might
grow, as an acorn does, absorbing light, heat, electricity
— or thought; for, in recent times, such
transference of energy has become a familiar idea;
but the simplest figure, at first, is that of a perfect
comet — say that of 1843 — which
drops from space, in a straight line, at the regular
acceleration of speed, directly into the sun, and after
wheeling sharply about it, in heat that ought to dissipate
any known substance, turns back unharmed, in defiance
of law, by the path on which it came. The mind,
by analogy, may figure as such a comet, the better
because it also defies law.
Motion is the ultimate object of
science, and measures of motion are many; but with
thought as with matter, the true measure is mass in
its astronomic sense — the sum or difference
of attractive forces. Science has quite enough
trouble in measuring its material motions without
volunteering help to the historian, but the historian
needs not much help to measure some kinds of social
movement; and especially in the nineteenth century,
society by common accord agreed in measuring its progress
by the coal-output. The ratio of increase in the
volume of coal-power may serve as dynamometer.
The coal-output of the world, speaking
roughly, doubled every ten years between 1840 and
1900, in the form of utilized power, for the ton of
coal yielded three or four times as much power in
1900 as in 1840. Rapid as this rate of acceleration
in volume seems, it may be tested in a thousand ways
without greatly reducing it. Perhaps the ocean
steamer is nearest unity and easiest to measure, for
any one might hire, in 1905, for a small sum of money,
the use of 30,000 steam-horse-power to cross the ocean,
and by halving this figure every ten years, he got
back to 234 horse-power for 1835, which was accuracy
enough for his purposes. In truth, his chief
trouble came not from the ratio in volume of heat,
but from the intensity, since he could get no basis
for a ratio there. All ages of history have known
high intensities, like the iron-furnace, the burning-glass,
the blow-pipe; but no society has ever used high intensities
on any large scale till now, nor can a mere bystander
decide what range of temperature is now in common
use. Loosely guessing that science controls habitually
the whole range from absolute zero to 3000 degrees
Centigrade, one might assume, for convenience, that
the ten-year ratio for volume could be used temporarily
for intensity; and still there remained a ratio to
be guessed for other forces than heat. Since
1800 scores of new forces had been discovered; old
forces had been raised to higher powers, as could
be measured in the navy-gun; great regions of chemistry
had been opened up, and connected with other regions
of physics. Within ten years a new universe of
force had been revealed in radiation. Complexity
had extended itself on immense horizons, and arithmetical
ratios were useless for any attempt at accuracy.
The force evolved seemed more like explosion than
gravitation, and followed closely the curve of steam;
but, at all events, the ten-year ratio seemed carefully
conservative. Unless the calculator was prepared
to be instantly overwhelmed by physical force and
mental complexity, he must stop there.
Thus, taking the year 1900 as the
starting point for carrying back the series, nothing
was easier than to assume a ten-year period of retardation
as far back as 1820, but beyond that point the statistician
failed, and only the mathematician could help.
Laplace would have found it child’s-play to fix
a ratio of progression in mathematical science between
Descartes, Leibnitz, Newton, and himself. Watt
could have given in pounds the increase of power between
Newcomen’s engines and his own. Volta and
Benjamin Franklin would have stated their progress
as absolute creation of power. Dalton could have
measured minutely his advance on Boerhaave. Napoleon
I must have had a distinct notion of his own numerical
relation to Louis XIV. No one in 1789 doubted
the progress of force, least of all those who were
to lose their heads by it.
Pending agreement between these
authorities, theory may assume what it likes —
say a fifty, or even a five-and-twenty-year period
of reduplication for the eighteenth century, for the
period matters little until the acceleration itself
is admitted. The subject is even more amusing
in the seventeenth than in the eighteenth century,
because Galileo and Kepler, Descartes, Huygens, and
Isaac Newton took vast pains to fix the laws of acceleration
for moving bodies, while Lord Bacon and William Harvey
were content with showing experimentally the fact of
acceleration in knowledge; but from their combined
results a historian might be tempted to maintain a
similar rate of movement back to 1600, subject to
correction from the historians of mathematics.
The mathematicians might carry their
calculations back as far as the fourteenth century
when algebra seems to have become for the first time
the standard measure of mechanical progress in western
Europe; for not only Copernicus and Tycho Brahe, but
even artists like Leonardo, Michael Angelo, and Albert
Durer worked by mathematical processes, and their
testimony would probably give results more exact than
that of Montaigne or Shakespeare; but, to save trouble,
one might tentatively carry back the same ratio of
acceleration, or retardation, to the year 1400, with
the help of Columbus and Gutenberg, so taking a uniform
rate during the whole four centuries (1400-1800),
and leaving to statisticians the task of correcting
it.
Or better, one might, for convenience,
use the formula of squares to serve for a law of mind.
Any other formula would do as well, either of chemical
explosion, or electrolysis, or vegetable growth, or
of expansion or contraction in innumerable forms; but
this happens to be simple and convenient. Its
force increases in the direct ratio of its squares.
As the human meteoroid approached the sun or centre
of attractive force, the attraction of one century
squared itself to give the measure of attraction in
the next.
Behind the year 1400, the process
certainly went on, but the progress became so slight
as to be hardly measurable. What was gained in
the east or elsewhere, cannot be known; but forces,
called loosely Greek fire and gunpowder, came into
use in the west in the thirteenth century, as well
as instruments like the compass, the blow-pipe, clocks
and spectacles, and materials like paper; Arabic notation
and algebra were introduced, while metaphysics and
theology acted as violent stimulants to mind.
An architect might detect a sequence between the Church
of St. Peter’s at Rome, the Amiens Cathedral,
the Duomo at Pisa, San Marco at Venice, Sancta Sofia
at Constantinople and the churches at Ravenna.
All the historian dares affirm is that a sequence is
manifestly there, and he has a right to carry back
his ratio, to represent the fact, without assuming
its numerical correctness. On the human mind
as a moving body, the break in acceleration in the
Middle Ages is only apparent; the attraction worked
through shifting forms of force, as the sun works
by light or heat, electricity, gravitation, or what
not, on different organs with different sensibilities,
but with invariable law.
The science of prehistoric man has
no value except to prove that the law went back into
indefinite antiquity. A stone arrowhead is as
convincing as a steam-engine. The values were
as clear a hundred thousand years ago as now, and
extended equally over the whole world. The motion
at last became infinitely slight, but cannot be proved
to have stopped. The motion of Newton’s
comet at aphelion may be equally slight. To evolutionists
may be left the processes of evolution; to historians
the single interest is the law of reaction between
force and force — between mind and nature
— the law of progress.
The great division of history into
phases by Turgot and Comte first affirmed this law
in its outlines by asserting the unity of progress,
for a mere phase interrupts no growth, and nature shows
innumerable such phases. The development of coal-power
in the nineteenth century furnished the first means
of assigning closer values to the elements; and the
appearance of supersensual forces towards 1900 made
this calculation a pressing necessity; since the next
step became infinitely serious.
A law of acceleration, definite
and constant as any law of mechanics, cannot be supposed
to relax its energy to suit the convenience of man.
No one is likely to suggest a theory that man’s
convenience had been consulted by Nature at any time,
or that Nature has consulted the convenience of any
of her creations, except perhaps the Terebratula.
In every age man has bitterly and justly complained
that Nature hurried and hustled him, for inertia almost
invariably has ended in tragedy. Resistance is
its law, and resistance to superior mass is futile
and fatal.
Fifty years ago, science took for
granted that the rate of acceleration could not last.
The world forgets quickly, but even today the habit
remains of founding statistics on the faith that consumption
will continue nearly stationary. Two generations,
with John Stuart Mill, talked of this stationary period,
which was to follow the explosion of new power.
All the men who were elderly in the forties died in
this faith, and other men grew old nursing the same
conviction, and happy in it; while science, for fifty
years, permitted, or encouraged, society to think that
force would prove to be limited in supply. This
mental inertia of science lasted through the eighties
before showing signs of breaking up; and nothing short
of radium fairly wakened men to the fact, long since
evident, that force was inexhaustible. Even then
the scientific authorities vehemently resisted.
Nothing so revolutionary had happened
since the year 300. Thought had more than once
been upset, but never caught and whirled about in
the vortex of infinite forces. Power leaped from
every atom, and enough of it to supply the stellar
universe showed itself running to waste at every pore
of matter. Man could no longer hold it off.
Forces grasped his wrists and flung him about as though
he had hold of a live wire or a runaway automobile;
which was very nearly the exact truth for the purposes
of an elderly and timid single gentleman in Paris,
who never drove down the Champs Elysees without expecting
an accident, and commonly witnessing one; or found
himself in the neighborhood of an official without
calculating the chances of a bomb. So long as
the rates of progress held good, these bombs would
double in force and number every ten years.
Impossibilities no longer stood
in the way. One’s life had fattened on
impossibilities. Before the boy was six years
old, he had seen four impossibilities made actual
— the ocean-steamer, the railway, the electric
telegraph, and the Daguerreotype; nor could he ever
learn which of the four had most hurried others to
come. He had seen the coal-output of the United
States grow from nothing to three hundred million
tons or more. What was far more serious, he had
seen the number of minds, engaged in pursuing force
— the truest measure of its attraction —
increase from a few scores or hundreds, in 1838, to
many thousands in 1905, trained to sharpness never
before reached, and armed with instruments amounting
to new senses of indefinite power and accuracy, while
they chased force into hiding-places where Nature
herself had never known it to be, making analyses that
contradicted being, and syntheses that endangered the
elements. No one could say that the social mind
now failed to respond to new force, even when the
new force annoyed it horribly. Every day Nature
violently revolted, causing so-called accidents with
enormous destruction of property and life, while plainly
laughing at man, who helplessly groaned and shrieked
and shuddered, but never for a single instant could
stop. The railways alone approached the carnage
of war; automobiles and fire-arms ravaged society,
until an earthquake became almost a nervous relaxation.
An immense volume of force had detached itself from
the unknown universe of energy, while still vaster
reservoirs, supposed to be infinite, steadily revealed
themselves, attracting mankind with more compulsive
course than all the Pontic Seas or Gods or Gold that
ever existed, and feeling still less of retiring ebb.
In 1850, science would have smiled
at such a romance as this, but, in 1900, as far as
history could learn, few men of science thought it
a laughing matter. If a perplexed but laborious
follower could venture to guess their drift, it seemed
in their minds a toss-up between anarchy and order.
Unless they should be more honest with themselves
in the future than ever they were in the past, they
would be more astonished than their followers when
they reached the end. If Karl Pearson’s
notions of the universe were sound, men like Galileo,
Descartes, Leibnitz, and Newton should have stopped
the progress of science before 1700, supposing them
to have been honest in the religious convictions they
expressed. In 1900 they were plainly forced back;
on faith in a unity unproved and an order they had
themselves disproved. They had reduced their
universe to a series of relations to themselves.
They had reduced themselves to motion in a universe
of motions, with an acceleration, in their own case
of vertiginous violence. With the correctness
of their science, history had no right to meddle,
since their science now lay in a plane where scarcely
one or two hundred minds in the world could follow
its mathematical processes; but bombs educate vigorously,
and even wireless telegraphy or airships might require
the reconstruction of society. If any analogy
whatever existed between the human mind, on one side,
and the laws of motion, on the other, the mind had
already entered a field of attraction so violent that
it must immediately pass beyond, into new equilibrium,
like the Comet of Newton, to suffer dissipation altogether,
like meteoroids in the earth’s atmosphere.
If it behaved like an explosive, it must rapidly recover
equilibrium; if it behaved like a vegetable, it must
reach its limits of growth; and even if it acted like
the earlier creations of energy — the saurians
and sharks — it must have nearly reached
the limits of its expansion. If science were
to go on doubling or quadrupling its complexities
every ten years, even mathematics would soon succumb.
An average mind had succumbed already in 1850; it
could no longer understand the problem in 1900.
Fortunately, a student of history
had no responsibility for the problem; he took it
as science gave it, and waited only to be taught.
With science or with society, he had no quarrel and
claimed no share of authority. He had never been
able to acquire knowledge, still less to impart it;
and if he had, at times, felt serious differences
with the American of the nineteenth century, he felt
none with the American of the twentieth. For this
new creation, born since 1900, a historian asked no
longer to be teacher or even friend; he asked only
to be a pupil, and promised to be docile, for once,
even though trodden under foot; for he could see that
the new American — the child of incalculable
coal-power, chemical power, electric power, and radiating
energy, as well as of new forces yet undetermined
— must be a sort of God compared with any
former creation of nature. At the rate of progress
since 1800, every American who lived into the year
2000 would know how to control unlimited power.
He would think in complexities unimaginable to an
earlier mind. He would deal with problems altogether
beyond the range of earlier society. To him the
nineteenth century would stand on the same plane with
the fourth — equally childlike —
and he would only wonder how both of them, knowing
so little, and so weak in force, should have done
so much. Perhaps even he might go back, in 1964,
to sit with Gibbon on the steps of Ara Coeli.
Meanwhile he was getting education.
With that, a teacher who had failed to educate even
the generation of 1870, dared not interfere.
The new forces would educate. History saw few
lessons in the past that would be useful in the future;
but one, at least, it did see. The attempt of
the American of 1800 to educate the American of 1900
had not often been surpassed for folly; and since
1800 the forces and their complications had increased
a thousand times or more. The attempt of the
American of 1900 to educate the American of 2000,
must be even blinder than that of the Congressman
of 1800, except so far as he had learned his ignorance.
During a million or two of years, every generation
in turn had toiled with endless agony to attain and
apply power, all the while betraying the deepest alarm
and horror at the power they created. The teacher
of 1900, if foolhardy, might stimulate; if foolish,
might resist; if intelligent, might balance, as wise
and foolish have often tried to do from the beginning;
but the forces would continue to educate, and the
mind would continue to react. All the teacher
could hope was to teach it reaction.
Even there his difficulty was extreme.
The most elementary books of science betrayed the
inadequacy of old implements of thought. Chapter
after chapter closed with phrases such as one never
met in older literature: “The cause of this
phenomenon is not understood”; “science
no longer ventures to explain causes”; “the
first step towards a causal explanation still remains
to be taken”; “opinions are very much
divided”; “in spite of the contradictions
involved”; “science gets on only by adopting
different theories, sometimes contradictory.”
Evidently the new American would need to think in
contradictions, and instead of Kant’s famous
four antinomies, the new universe would know no law
that could not be proved by its anti-law.
To educate — one’s
self to begin with — had been the effort
of one’s life for sixty years; and the difficulties
of education had gone on doubling with the coal-output,
until the prospect of waiting another ten years, in
order to face a seventh doubling of complexities,
allured one’s imagination but slightly.
The law of acceleration was definite, and did not
require ten years more study except to show whether
it held good. No scheme could be suggested to
the new American, and no fault needed to be found,
or complaint made; but the next great influx of new
forces seemed near at hand, and its style of education
promised to be violently coercive. The movement
from unity into multiplicity, between 1200 and 1900,
was unbroken in sequence, and rapid in acceleration.
Prolonged one generation longer, it would require a
new social mind. As though thought were common
salt in indefinite solution it must enter a new phase
subject to new laws. Thus far, since five or
ten thousand years, the mind had successfully reacted,
and nothing yet proved that it would fail to react
— but it would need to jump.
