opinions exert their influence on those who cultivate the
sciences, as well as on the rest of the community. They
facilitate the natural impulse of the mind to the highest regions
of thought, and they naturally prepare it to conceive a sublime -
nay, almost a divine - love of truth. Men of science at such
periods are consequently carried away by theory; and it even
happens that they frequently conceive an inconsiderate contempt
for the practical part of learning. "Archimedes," says Plutarch,
"was of so lofty a spirit, that he never condescended to write
any treatise on the manner of constructing all these engines of
offence and defence. And as he held this science of inventing
and putting together engines, and all arts generally speaking
which tended to any usetul end in practice, to be vile, low, and
mercenary, he spent his talents and his studious hours in writing
of those things only whose beauty and subtilty had in them no
admixture of necessity." Such is the aristocratic aim of science;
in democratic nations it cannot be the same.
The greater part of the men who constitute these nations are
extremely eager in the pursuit of actual and physical
gratification. As they are always dissatisfied with the position
which they occupy, and are always free to leave it, they think of
nothing but the means of changing their fortune, or of increasing
it. To minds thus predisposed, every new method which leads by a
shorter road to wealth, every machine which spares labor, every
instrument which diminishes the cost of production, every
discovery which facilitates pleasures or augments them, seems to
be the grandest effort of the human intellect. It is chiefly
from these motives that a democratic people addicts itself to
scientific pursuits - that it understands, and that it respects
them. In aristocratic ages, science is more particularly called
upon to furnish gratification to the mind; in democracies, to the
body. You may be sure that the more a nation is democratic,
enlightened, and free, the greater will be the number of these
interested promoters of scientific genius, and the more will
discoveries immediately applicable to productive industry confer
gain, fame, and even power on their authors. For in democracies
the working class takes a part in public affairs; and public
honors, as well as pecuniary remuneration, may be awarded to
those who deserve them. In a community thus organized it may
easily be conceived that the human mind may be led insensibly to
the neglect of theory; and that it is urged, on the contrary,
with unparalleled vehemence to the applications of science, or at
least to that portion of theoretical science which is necessary
to those who make such applications. In vain will some innate
propensity raise the mind towards the loftier spheres of the
intellect; interest draws it down to the middle zone. There it
may develop all its energy and restless activity, there it may
engender all its wonders. These very Americans, who have not
discovered one of the general laws of mechanics, have introduced
into navigation an engine which changes the aspect of the world.
Assuredly I do not content that the democratic nations of
our time are destined to witness the extinction of the
transcendent luminaries of man's intelligence, nor even that no
new lights will ever start into existence. At the age at which
the world has now arrived, and amongst so many cultivated
nations, perpetually excited by the fever of productive industry,
the bonds which connect the different parts of science together
cannot fail to strike the observation; and the taste for
practical science itself, if it be enlightened, ought to lead men
not to neglect theory. In the midst of such numberless attempted
applications of so many experiments, repeated every day, it is
almost impossible that general laws should not frequently be
brought to light; so that great discoveries would be frequent,
though great inventors be rare. I believe, moreover, in the high
calling of scientific minds. If the democratic principle does
not, on the one hand, induce men to cultivate science for its own
sake, on the other it enormously increases the number of those
