young person would have an excuse for not studying, by stating,
as is most frequently done, that the only pursuits followed at
Cambridge, classics and mathematics, are not adapted either to
his taste, or to the wants of his after life. His friends and
relatives would then reasonably expect every student to have
acquired distinction in SOME pursuit. If it should be feared
that this plan would lead to too great a diversity of pursuits in
the same individual, a limitation might be placed upon the number
of examinations into which the same person might be permitted to
enter. It might also be desirable not to restrict the whole of
these examinations to the third year, but to allow the student to
enter on some portion of them in the first or second year, if he
should prefer it.
By such an arrangement, which would scarcely interfere seriously
with our other examinations, we should, I think, be enabled
effectually to keep pace with the wants of society, and retaining
fully our power and our right to direct the studies of those who
are intended for the church, as well as of those who aspire to
the various offices connected with our academical institutions;
we should, at the same time, open a field of honourable ambition
to multitudes, who, from the exclusive nature of our present
studies, leave us with but a very limited addition to their stock
of knowledge.
Much more might be said on a subject so important to the
interests of the country, as well as of our university, but my
wish is merely to open it for our own consideration and
discussion. We have already done so much for the improvement of
our system of instruction, that public opinion will not reproach
us for any unwillingness to alter. It is our first duty to be
well satisfied that we can improve: such alterations ought only
to be the result of a most mature consideration, and of a free
interchange of sentiments on the subject, in order that we may
condense upon the question the accumulated judgment of many
minds.
It is in some measure to be attributed to the defects of our
system of education, that scientific knowledge scarcely exists
amongst the higher classes of society. The discussions in the
Houses of Lords or of Commons, which arise on the occurrence of
any subjects connected with science, sufficiently prove this
fact, which, if I had consulted the extremely limited nature of
my personal experience, I should, perhaps, have doubted.
CHAPTER II.
OF THE INDUCEMENTS TO INDIVIDUALS TO CULTIVATE SCIENCE.
Interest or inclination form the primary and ruling motives in
this matter: and both these exert greater or less proportionate
influence in each of the respective cases to be examined.
SECTION 1.
PROFESSIONAL IMPULSES.
A large portion of those who are impelled by ambition or
necessity to advance themselves in the world, make choice of some
profession in which they imagine their talents likely to be
rewarded with success; and there are peculiar advantages
resulting to each from this classification of society into
professions. The ESPRIT DE CORPS frequently overpowers the
jealousy which exists between individuals, and pushes on to
advantageous situations some of the more fortunate of the
profession; whilst, on the other hand, any injury or insult
offered to the weakest, is redressed or resented by the whole
body. There are other advantages which are perhaps of more
importance to the public. The numbers which compose the learned
professions in England are so considerable, that a kind of public
opinion is generated amongst them, which powerfully tends to
repress conduct that is injurious either to the profession or to
the public. Again, the mutual jealousy and rivalry excited
amongst the whole body is so considerable, that although the rank
and estimation which an individual holds in the profession may be
most unfairly appreciated, by taking the opinion of his rival;
yet few estimations will be found generally more correct than the
opinion of a whole profession on the merits of any one of its
body. This test is of great value to the public, and becomes the
more so, in proportion to the difficulty of the study to which
the profession is devoted. It is by availing themselves of it
that men of sense and judgment, who have occasion for the
services of professional persons, are, in a great measure, guided
in their choice.
The pursuit of science does not, in England, constitute a
distinct profession, as it does in many other countries. It is
therefore, on that ground alone, deprived of many of the
advantages which attach to professions. One of its greatest
misfortunes arises from this circumstance; for the subjects on
which it is conversant are so difficult, and require such
unremitted devotion of time, that few who have not spent years in
their study can judge of the relative knowledge of those who
pursue them. It follows, therefore, that the public, and even
that men of sound sense and discernment, can scarcely find means
to distinguish between the possessors of knowledge, in the
present day, merely elementary, and those whose acquirements are
of the highest order. This remark applies with peculiar force to
all the more difficult applications of mathematics; and the fact
is calculated to check the energies of those who only look to
reputation in England.
As there exists with us no peculiar class professedly devoted to
science, it frequently happens that when a situation, requiring
for the proper fulfilment of its duties considerable scientific
attainments, is vacant, it becomes necessary to select from among
amateurs, or rather from among persons whose chief attention has
been bestowed on other subjects, and to whom science has been
only an occasional pursuit. A certain quantity of scientific
knowledge is of course possessed by individuals in many
professions; and when added to the professional acquirements of
the army, the navy, or to the knowledge of the merchant, is
highly meritorious: but it is obvious that this may become, when
separated from the profession, quite insignificant as the basis
of a scientific reputation.
To those who have chosen the profession of medicine, a knowledge
of chemistry, and of some branches of natural history, and,
indeed, of several other departments of science, affords useful
assistance. Some of the most valuable names which adorn the
history of English science have been connected with this
profession.
The causes which induce the selection of the clerical profession
are not often connected with science; and it is, perhaps, a
question of considerable doubt whether it is desirable to hold
out to its members hopes of advancement from such acquirements.
As a source of recreation, nothing can be more fit to occupy the
attention of a divine; and our church may boast, in the present
as in past times, that the domain of science has been extended by
some of its brightest ornaments.
In England, the profession of the law is that which seems to hold
out the strongest attraction to talent, from the circumstance,
that in it ability, coupled with exertion, even though unaided by
patronage, cannot fail of obtaining reward. It is frequently
chosen as an introduction to public life. It also presents great
advantages, from its being a qualification for many situations
more or less remotely connected with it, as well as from the
circumstance that several of the highest officers of the state
must necessarily have sprung from its ranks.
A powerful attraction exists, therefore, to the promotion of a
study and of duties of all others engrossing the time most
completely, and which is less benefited than most others by any
acquaintance with science. This is one amongst the causes why it
so very rarely happens that men in public situations are at all
conversant even with the commonest branches of scientific
knowledge, and why scarcely an instance can be cited of such
persons acquiring a reputation by any discoveries of their own.
But, however consistent other sciences may be with professional
avocations, there is one which, from its extreme difficulty, and
the overwhelming attention which it demands, can only be pursued
with success by those whose leisure is undisturbed by other
claims. To be well acquainted with the present state of
mathematics, is no easy task; but to add to the powers which that
science possesses, is likely to be the lot of but few English
philosophers.
SECTION 2.
OF NATIONAL ENCOURAGEMENT.
The little encouragement which at all previous periods has been
afforded by the English Government to the authors of useful
discoveries, or of new and valuable inventions, is justified on
the following grounds:
1. The public, who consume the new commodity or profit by the
new invention, are much better judges of its merit than the
government can be.
2. The reward which arises from the sale of the commodity is
usually much larger than that which government would be justified
in bestowing; and it is exactly proportioned to the consumption,
that is, to the want which the public feel for the new article.
It must be admitted that, as general principles, these are
correct: there are, however, exceptions which flow necessarily
from the very reasoning from which they were deduced. Without
entering minutely into these exceptions, it will be sufficient to
show that all abstract truth is entirely excluded from reward
under this system. It is only the application of principles to
common life which can be thus rewarded. A few instances may
perhaps render this position more evident. The principle of the
hydrostatic paradox was known as a speculative truth in the time
of Stevinus; [About the year 1600] and its application to raising
heavy weights has long been stated in elementary treatises on
natural philosophy, as well as constantly exhibited in lectures.
Yet, it may fairly be regarded as a mere abstract principle,
until the late Mr. Bramah, by substituting a pump instead of the
smaller column, converted it into a most valuable and powerful
engine.—The principle of the convertibility of the centres of
oscillation and suspension in the pendulum, discovered by Huygens
more than a century and a half ago, remained, until within these
few years, a sterile, though most elegant proposition; when,
after being hinted at by Prony, and distinctly pointed out by
Bonenberger, it was employed by Captain Kater as the foundation
of a most convenient practical method of determining the length
of the pendulum.—The interval which separated the discovery, by
Dr. Black, of latent heat, from the beautiful and successful
application of it to the steam engine, was comparatively short;
but it required the efforts of two minds; and both were of the
highest order.—The influence of electricity in producing
decompositions, although of inestimable value as an instrument of
discovery in chemical inquiries, can hardly be said to have been
applied to the practical purposes of life, until the same
powerful genius which detected the principle, applied it, by a
singular felicity of reasoning, to arrest the corrosion of the
copper-sheathing of vessels. That admirably connected chain of
reasoning, the truth of which is confirmed by its very failure as
a remedy, will probably at some future day supply, by its
successful application, a new proof of the position we are
endeavouring to establish.
[I am authorised in stating, that this was regarded by Laplace as
the greatest of Sir Humphry Davy’s discoveries. It did not fail
in producing the effect foreseen by Sir H. Davy,—the preventing
the corrosion of the copper; but it failed as a cure of the evil,
by producing one of an OPPOSITE character; either by preserving
too perfectly from decay the surface of the copper, or by
rendering it negative, it allowed marine animals and vegetables
to accumulate on its surface, and thus impede the progress
