The Aims of Education (1929)
Culture is activity of thought, and receptiveness to beauty and
humane feeling. Scraps of information have nothing to do with it. A
merely well-informed man is the most useless bore on God's earth. What
we should aim at producing is men who possess both culture and expert
knowledge in some special direction. Their expert knowledge will give
them the ground to start from, and their culture will lead them as deep
as philosophy and as high as art. We have to remember that the valuable
intellectual development is self development, and that it mostly takes
place between the ages of sixteen and thirty. As to training, the most
important part is given by mothers before the age of twelve. A saying
due to Archbishop Temple illustrates my meaning. Surprise was expressed
at the success in after-life of a man, who as a boy at Rugby had been
somewhat undistinguished. He answered, "It is not what they are at
eighteen, it is what they become afterwards that matters."
In training a child to activity of thought, above all things we
must beware of what I will call "inert ideas" -- that is to say, ideas
that are merely received into the mind without being utilised, or
tested, or thrown into fresh combinations.
In the history of education, the most striking phenomenon is that
schools of learning, which at one epoch are alive with a ferment of
genius, in a succeeding generation exhibit merely pedantry and routine.
The reason is, that they are overladen with inert ideas. Education with
inert ideas is not only useless: it is, above all things, harmful --
Corruptio optimi, pessima. Except at rare intervals of intellectual
ferment, education in the past has been radically infected with inert
ideas. That is the reason why uneducated clever women, who have seen
much of the world, are in middle life so much the most cultured part of
the community. They have been saved from this horrible burden of inert
ideas. Every intellectual revolution which has ever stirred humanity
into greatness has been a passionate protest against inert ideas. Then,
alas, with pathetic ignorance of human psychology, it has proceeded by
some educational scheme to bind humanity afresh with inert ideas of its
own fashioning.
Let us now ask how in our system of education we are to guard
against this mental dryrot. We enunciate two educational commandments,
"Do not teach too many subjects," and again, "What you teach, teach
thoroughly."
The result of teaching small parts of a large number of subjects
is the passive reception of disconnected ideas, not illumined with any
spark of vitality. Let the main ideas which are introduced into a
child's education be few and important, and let them be thrown into
every combination possible. The child should make them his own, and
should understand their application here and now in the circumstances
of his actual life. From the very beginning of his education, the child
should experience the joy of discovery. The discovery which he has to
make, is that general ideas give an understanding of that stream of
events which pours through his life, which is his life. By
understanding I mean more than a mere logical analysis, though that is
included. I mean "understanding' in the sense in which it is used in
the French proverb, "To understand all, is to forgive all." Pedants
sneer at an education which is useful. But if education is not useful,
what is it? Is it a talent, to be hidden away in a napkin? Of course,
education should be useful, whatever your aim in life. It was useful to
Saint Augustine and it was useful to Napoleon. It is useful, because
understanding is useful.
I pass lightly over that understanding which should be given by
the literary side of education. Nor do I wish to be supposed to
pronounce on the relative merits of a classical or a modern curriculum.
I would only remark that the understanding which we want is an
understanding of an insistent present. The only use of a knowledge of
the past is to equip us for the present. No more deadly harm can be
done to young minds than by depreciation of the present. The present
contains all that there is. It is holy ground; for it is the past, and
it is the future. At the same time it must be observed that an age is
no less past if it existed two hundred years ago than if it existed two
thousand years ago. Do not be deceived by the pedantry of dates. The
ages of Shakespeare and of Moliere are no less past than are the ages
of Sophocles and of Virgil. The communion of saints is a great and
inspiring assemblage, but it has only one possible hall of meeting, and
that is, the present, and the mere lapse of time through which any
particular group of saints must travel to reach that meeting-place,
makes very little difference.
Passing now to the scientific and logical side of education, we
remember that here also ideas which are not utilised are positively
harmful. By utilising an idea, I mean relating it to that stream,
compounded of sense perceptions, feelings, hopes, desires, and of
mental activities adjusting thought to thought, which forms our life. I
can imagine a set of beings which might fortify their souls by
passively reviewing disconnected ideas. Humanity is not built that way
except perhaps some editors of newspapers.
In scientific training, the first thing to do with an idea is to
prove it. But allow me for one moment to extend the meaning of "prove";
I mean -- to prove its worth. Now an idea is not worth much unless the
propositions in which it is embodied are true. Accordingly an essential
part of the proof of an idea is the proof, either by experiment or by
logic, of the truth of the propositions. But it is not essential that
this proof of the truth should constitute the first introduction to the
idea. After all, its assertion by the authority of respectable teachers
is sufficient evidence to begin with. In our first contact with a set
of propositions, we commence by appreciating their importance. That is
what we all do in after-life. We do not attempt, in the strict sense,
to prove or to disprove anything, unless its importance makes it worthy
of that honour. These two processes of proof, in the narrow sense, and
of appreciation, do not require a rigid separation in time. Both can be
proceeded with nearly concurrently. But in so far as either process
must have the priority, it should be that of appreciation by use.
Furthermore, we should not endeavour to use propositions in
isolation. Emphatically I do not mean, a neat little set of experiments
to illustrate Proposition I and then the proof of Proposition I, a neat
little set of experiments to illustrate Proposition II and then the
proof of Proposition II, and so on to the end of the book. Nothing
could be more boring. Interrelated truths are utilised en bloc, and the
various propositions are employed in any order, and with any
reiteration. Choose some important applications of your theoretical
subject; and study them concurrently with the systematic theoretical
exposition. Keep the theoretical exposition short and simple, but let
it be strict and rigid so far as it goes. It should not be too long for
it to be easily known with thoroughness and accuracy. The consequences
of a plethora of half-digested theoretical knowledge are deplorable.
Also the theory should not be muddled up with the practice. The child
should have no doubt when it is proving and when it is utilising. My
point is that what is proved should be utilised, and that what is
utilised should -- so far, as is practicable -- be proved. I am far
from asserting that proof and utilisation are the same thing.
At this point of my discourse, I can most directly carry forward
my argument in the outward form of a digression. We are only just
realising that the art and science of education require a genius and a
study of their own; and that this genius and this science are more than
a bare knowledge of some branch of science or of literature. This truth
was partially perceived in the past generation; and headmasters,
somewhat crudely, were apt to supersede learning in their colleagues by
requiring left-hand bowling and a taste for football. But culture is
more than cricket, and more than football, and more than extent of
knowledge.
Education is the acquisition of
the art of the utilisation of
knowledge. This is an art very difficult to impart. Whenever a
textbook
is written of real educational worth, you may be quite certain that
some reviewer will say that it will be difficult to teach from it. Of
course it will be difficult to teach from it. If it were easy, the book
ought to be burned; for it cannot be educational. In education, as
elsewhere, the broad primrose path leads to a nasty place. This evil
path is represented by a book or a set of lectures which will
practically enable the student to learn by heart all the questions
likely to be asked at the next external examination. And I may say in
passing that no educational system is possible unless every question
directly asked of a pupil at any examination is either framed or
modified by the actual teacher of that pupil in that subject. The
external assessor may report on the curriculum or on the performance of
the pupils, but never should be allowed to ask the pupil a question
which has not been strictly supervised by the actual teacher, or at
least inspired by a long conference with him. There are a few
exceptions to this rule, but they are exceptions, and could easily be
allowed for under the general rule.
We now return to my previous point, that theoretical ideas should
always find important applications within the pupil's curriculum. This
is not an easy doctrine to apply, but a very hard one. It contains
within itself the problem of keeping knowledge alive, of preventing it
from becoming inert, which is the central problem of all education.
The best procedure will depend on several factors, none of which
can be neglected, namely, the genius of the teacher, the intellectual
type of the pupils, their prospects in life, the opportunities offered
by the immediate surroundings of the school and allied factors of this
sort. It is for this reason that the uniform external examination is so
deadly. We do not denounce it because we are cranks, and like
denouncing established things. We are not so childish. Also, of course,
such examinations have their use in testing slackness. Our reason of
dislike is very definite and very practical. It kills the best part of
culture. When you analyse in the light of experience the central task
of education, you find that its successful accomplishment depends on a
delicate adjustment of many variable factors. The reason is that we are
dealing with human minds, and not with dead matter. The evocation of
curiosity, of judgment, of the power of mastering a complicated tangle
of circumstances, the use of theory in giving foresight in special
cases all these powers are not to be imparted by a set rule embodied in
one schedule of examination subjects.
I appeal to you, as practical teachers. With good discipline, it
is always possible to pump into the minds of a class a certain quantity
of inert knowledge. You take a text-book and make them learn it. So
far, so good. The child then knows how to solve a quadratic equation.
But what is the point of teaching a child to solve a quadratic
equation? There is a traditional answer to this question. It runs thus:
The mind is an instrument, you first sharpen it, and then use it; the
acquisition of the power of solving a quadratic equation is part of the
process of sharpening the mind. Now there is just enough truth in this
answer to have made it live through the ages. But for all its
halftruth, it embodies a radical error which bids fair to stifle the
genius
of the modern world. I do not know who was first responsible for this
analogy of the mind to a dead instrument. For aught I know, it may have
been one of the seven wise men of Greece, or a committee of the whole
lot of them. Whoever was the originator, there can be no doubt of the
authority which it has acquired by the continuous approval bestowed
upon it by eminent persons. But whatever its weight of authority,
whatever the high approval which it can quote, I have no hesitation in
denouncing it as one of the most fatal, erroneous, and dangerous
conceptions ever introduced into the theory of education. The mind is
never passive; it is a perpetual activity, delicate, receptive,
responsive to stimulus. You cannot postpone its life until you have
sharpened it. Whatever interest attaches to your subject-matter must be
evoked here and now; whatever powers you are strengthening in the
pupil, must be exercised here and now; whatever possibilities of mental
life your teaching should impart, must be exhibited here and now. That
is the golden rule of education, and a very difficult rule to follow.
The difficulty is just this: the apprehension of general ideas,
intellectual habits of mind, and pleasurable interest in mental
achievement can be evoked by no form of words, however accurately
adjusted. All practical teachers know that education is a patient
process of the mastery of details, minute by minute, hour by hour, day
by day. There is no royal road to learning through an airy path of
brilliant generalizations. There is a proverb about the difficulty of
seeing the wood because of the trees. That difficulty is exactly the
point which I am enforcing. The problem of education is to make the
pupil see the wood by means of the trees.
The solution which I am urging,
is to eradicate the fatal
disconnection of subjects which kills the vitality of our modern
curriculum. There is only one subject-matter for education, and
that is
Life in all its manifestations. Instead of this single unity, we offer
children -- Algebra, from which nothing follows; Geometry, from which
nothing follows; Science, from which nothing follows; History, from
which nothing follows; a Couple of Languages, never mastered; and
lastly, most dreary of all, Literature, represented by plays of
Shakespeare, with philological notes and short analyses of plot and
character to be in substance committed to memory. Can such a list be
said to represent Life, as it is known in the midst of the living of
it?
The best that can be said of it is, that it is a rapid table of
contents which a deity might run over in his mind while he was thinking
of creating a world, and has not yet determined how to put it together.
Let us now return to quadratic equations. We still have on hand
the unanswered question. Why should children be taught their solution?
Unless quadratic equations fit into a connected curriculum, of course
there is no reason to teach anything about them. Furthermore, extensive
as should be the place of mathematics in a complete culture, I am a
little doubtful whether for many types of boys algebraic solutions of
quadratic equations do not lie on the specialist side of mathematics. I
may here remind you that as yet I have not said anything of the
psychology or the content of the specialism, which is so necessary a
part of an ideal education. But all that is an evasion of our real
question, and I merely state it in order to avoid being misunderstood
in my answer.
Quadratic equations are part of algebra, and algebra is the
intellectual instrument which has been created for rendering clear the
quantitative aspects of the world. There is no getting out of it.
Through and through the world is infected with quantity. To talk sense,
is to talk in quantities. It is no use saying that the nation is large,
-- How large? It is no use saying that radium is scarce, -- How scarce?
You cannot evade quantity. You may fly to poetry and to music, and
quantity and number will face you in your rhythms and your octaves.
Elegant intellects which despise the theory of quantity, are but half
developed. They are more to be pitied than blamed, The scraps of
gibberish, which in their school-days were taught to them in the name
of algebra, deserve some contempt. This question of the degeneration of
algebra into gibberish, both in word and in fact, affords a pathetic
instance of the uselessness of reforming educational schedules without
a clear conception of the attributes which you wish to evoke in the
living minds of the children. A few years ago there was an outcry that
school algebra, was in need of reform, but there was a general
agreement that graphs would put everything right. So all sorts of
things were extruded, and graphs were introduced. So far as I can see,
with no sort of idea behind them, but just graphs. Now every
examination paper has one or two questions on graphs. Personally I am
an enthusiastic adherent of graphs. But I wonder whether as yet we have
gained very much. You cannot put life into any schedule of general
education unless you succeed in exhibiting its relation to some
essential characteristic of all intelligent or emotional perception. lt
is a hard saying, but it is true; and I do not see how to make it any
easier. In making these little formal alterations you are beaten by the
very nature of things. You are pitted against too skilful an adversary,
who will see to it that the pea is always under the other thimble.
Reformation must begin at the other end. First, you must make up
your mind as to those quantitative aspects of the world which are
simple enough to be introduced into general education; then a schedule
of algebra should be framed which will about find its exemplification
in these applications. We need not fear for our pet graphs, they will
be there in plenty when we once begin to treat algebra as a serious
means of studying the world. Some of the simplest applications will be
found in the quantities which occur in the simplest study of society.
The curves of history are more vivid and more informing than the dry
catalogues of names and dates which comprise the greater part of that
arid school study. What purpose is effected by a catalogue of
undistinguished kings and queens? Tom, Dick, or Harry, they are all
dead. General resurrections are failures, and are better postponed. The
quantitative flux of the forces of modern society is capable of very
simple exhihition. Meanwhile, the idea of the variable, of the
function, of rate of change, of equations and their solution, of
elimination, are being studied as an abstract science for their own
sake. Not, of course, in the pompous phrases with which I am alluding
to them here, but with that iteration of simple special cases proper to
teaching.
If this course be followed. the route from Chaucer to the Black
Death, from the Black Death to modern Labour troubles, will connect the
tales of the mediaeval pilgrims with the abstract science of algebra,
both yielding diverse aspects of that single theme, Life. I know what
most of you are thinking at this point. It is that the exact course
which I have sketched out is not the particular one which you would
have chosen, or even see how to work. I quite agree. I am not claiming
that I could do it myself. But your objection is the precise reason why
a common external examination system is fatal to education. The process
of exhibiting the applications of knowledge must, for its success,
essentially depend on the character of the pupils and the genius of the
teacher. Of course I have left out the easiest applications with which
most of us are more at home. I mean the quantitative sides of sciences,
such as mechanics and physics.
Again, in the same connection we plot the statistics of social
phenomena against the time. We then eliminate the time between suitable
pairs. We can speculate how far we have exhibited a real causal
connection, or how far a mere temporal coincidence. We notice that we
might have plotted against the time one set of statistics for one
country and another set for another country, and thus, with suitable
choice of subjects, have obtained graphs which certainly exhibited mere
coincidence. Also other graphs exhibit obvious causal connections. We
wonder how to discriminate. And so are drawn on as far as we will.
But in considering this description, I must beg you to remember
what I have been insisting on above. In the first place, one train of
thought will not suit all groups of children. For example, I should
expect that artisan children will want something more concrete and, in
a sense, swifter than I have set down here. Perhaps I am wrong, but
that is what I should guess. In the second place, I am not
contemplating one beautiful lecture stimulating, once and for all, an
admiring class. That is not the way in which education proceeds. No;
all the time the pupils are hard at work solving examples drawing
graphs, and making experiments, until they have a thorough hold on the
whole subject. I am describing the interspersed explanations, the
directions which should be given to their thoughts. The pupils have got
to be made to feel that they are studying something, and are not merely
executing intellectual minuets.
Finally, if you are teaching pupils for some general examination,
the problem of sound teaching is greatly complicated. Have you ever
noticed the zig-zag moulding round a Norman arch? The ancient work is
beautiful, the modern work is hideous. The reason is, that the modern
work is done to exact measure, the ancient work is varied according to
the idiosyncrasy of the workman. Here it is crowded, and there it is
expanded. Now the essence of getting pupils through examinations is to
give equal weight to all parts of the schedule. But mankind is
naturally specialist. One man sees a whole subject, where another can
find only a few detached examples. I know that it seems contradictory
to allow for specialism in a curriculum especially designed for a broad
culture. Without contradictions the world would be simpler, and perhaps
duller. But I am certain that in education wherever you exclude
specialism you destroy life.
We now come to the other great branch of a general mathematical
education, namely Geometry. The same principles apply. The theoretical
part should be clear-cut, rigid, short, and important. Every
proposition not absolutely necessary to exhibit the main connection of
ideas should be cut out, but the great fundamental ideas should be all
there. No omission of concepts, such as those of Similarity and
Proportion. We must remember that, owing to the aid rendered by the
visual presence of a figure, Geometry is a field of unequalled
excellence for the exercise of the deductive faculties of reasoning.
Then, of course, there follows Geometrical Drawing, with its training
for the hand and eye.
But, like Algebra, Geometry and Geometrical Drawing must be
extended beyond the mere circle of geometrical ideas. In an industrial
neighbourhood, machinery and workshop practice form the appropriate
extension. For example, in the London Polytechnics this has been
achieved with conspicuous success. For many secondary schools I suggest
that surveying and maps are the natural applications. In particular,
plane-table surveying should lead pupils to a vivid apprehension of the
immediate application of geometric truths. Simple drawing apparatus, a
surveyor's chain, and a surveyor's compass, should enable the pupils to
rise from the survey and mensuration of a field to the construction of
the map of a small district. The best education is to be found in
gaining the utmost information from the simplest apparatus. The
provision of elaborate instruments is greatly to be deprecated. To have
constructed the map of a small district, to have considered its roads,
its contours, its geology, its climate, its relation to other
districts, the effects on the status of its inhabitants, will teach
more history and geography than any knowledge of Perkin Warbeck or of
Behren's Straits. I mean not a nebulous lecture on the subject, but a
serious investigation in which the real facts are definitely
ascertained by the aid of accurate theoretical knowledge. A typical
mathematical problem should be: Survey such and such a field, draw a
plan of it to such and such a scale, and find the area. It would be
quite a good procedure to impart the necessary geometrical propositions
without their proofs. Then, concurrently in the same term, the proofs
of the propositions would be learnt while the survey was being made.
Fortunately, the specialist side of education presents an easier
problem than does the provision of a general culture. For this there
are many reasons. One is that many of the principles of procedure to be
observed are the same in both cases, and it is unnecessary to
recapitulate. Another reason is that specialist training takes place --
or should take place -- at a more advanced stage of the pupil's course,
and thus there is easier material to work upon. But undoubtedly the
chief reason is that the specialist study is normally a study of
peculiar interest to the student. He is studying it because, for some
reason, he wants to know it. This makes all the difference. The general
culture is designed to foster an activity of mind; the specialist
course utilises this activity. But it does not do to lay too much
stress on these neat antitheses. As we have already seen, in the
general course foci of special interest will arise; and similarly in
the special study, the external connections of the subject drag thought
outwards.
Again, there is not one course of study which merely gives general
cultures and another which gives special knowledge. The subjects
pursued for the sake of a general education are special subjects
specially studied; and, on the other hand, one of the ways of
encouraging general mental activity is to foster a special devotion.
You may not divide the seamless coat of learning. What education has to
impart is an intimate sense for the power of ideas, for the beauty of
ideas, and for the structure of ideas, together with a particular body
of knowledge which has peculiar reference to the life of the being
possessing it.
The appreciation of the structure of ideas is that side of a
cultured mind which can only grow under the influence of a special
study. I mean that eye for the whole chess-board, for the bearing of
one set of ideas on another. Nothing but a special study can give any
appreciation for the exact formulation of general ideas, for their
relations when formulated, for their service in the comprehension of
life. A mind so disciplined should be both more abstract and more
concrete. It has been trained in the comprehension of abstract thought
and in the analysis of facts.
Finally, there should grow the most austere of all mental
qualities; I mean the sense for style. It is an aesthetic sense, based
on admiration for the direct attainment of a foreseen end, simply and
without waste. Style in art, style in literature, style in science,
style in logic, style in practical execution have fundamentally the
same aesthetic qualities, namely, attainment and restraint. The love of
a subject in itself and for itself, where it is not the sleepy pleasure
of pacing a mental quarter-deck, is the love of style as manifested in
that study.
Here we are brought back to the position from which we started,
the utility of education. Style, in its finest sense, is the last
acquirement of the educated mind; it is also the most useful. It
pervades the whole being. The administrator with a sense for style
hates waste; the engineer with a sense for style economises his
material; the artisan with a sense for style prefers good work. Style
is the ultimate morality of mind.
But above style, and above knowledge, there is something, a vague
shape like fate above the Greek gods. That something is Power. Style is
the fashioning of power, the restraining of power. But, after all, the
power of attainment of the desired end is fundamental. The first thing
is to get there. Do not bother about your style, but solve your
problem, justify the ways of God to man, administer your province, or
do whatever else is set before you.
Where, then, does style help? In this, with style the end is
attained without side issues, without raising undesirable
inflammations. With style you attain your end and nothing but your end.
With style the effect of your activity is calculable, and foresight is
the last gift of gods to men. With style your power is increased, for
your mind is not distracted with irrelevancies, and you are more likely
to attain your object. Now style is the exclusive privilege of the
expert. Whoever heard of the style of an amateur painter, of the style
of an amateur poet? Style is always the product of specialist study,
the peculiar contribution of specialism to culture.
English education in its present phase suffers from a lack of
definite aim, and from an external machinery which kills its vitality.
Hitherto in this address I have been considering the aims which should
govern education. In this respect England halts between two opinions.
It has not decided whether to produce amateurs or experts. The profound
change in the world which the nineteenth century has produced is that
the growth of knowledge has given foresight. The amateur is essentially
a man with appreciation and with immense versatility in mastering a
given routine. But he lacks the foresight which comes from special
knowledge. The object of this address is to suggest how to produce the
expert without loss of the essential virtues of the amateur. The
machinery of our secondary education is rigid where it should be
yielding, and lax where it should be rigid. Every school is bound on
pain of extinction to train its boys for a small set of definite
examinations. No headmaster has a free hand to develop his general
education or his specialist studies in accordance with the
opportunities of his school, which are created by its staff, its
environment, its class of boys, and its endowments. I suggest that no
system of external tests which aims primarily at examining individual
scholars can result in anything but educational waste.
Primarily it is the schools and not the scholars which should be
inspected. Each school should grant its own leaving certificates, based
on its own curriculum. The standards of these schools should be sampled
and corrected. But the first requisite for educational reform is the
school as a unit, with its approved curriculum based on its own needs,
and evolved by its own staff. If we fail to secure that, we simply fall
from one formalism into another, from one dung hill of inert ideas into
another.
In stating that the school is the
true educational unit in any
national system for the safeguarding of efficiency, I have conceived
the alternative system as being the external examination of the
individual scholar. But every Scylla is faced by its Charybdis
-- or,
in more homely language, there is a ditch on both sides of the road. It
will be equally fatal to education if we fall into the hands of a
supervising department which is under the impression that it can divide
all schools into two or three rigid categories, each type being forced
to adopt a rigid curriculum. When I say that the school is the
educational unit, I mean exactly what I say, no larger unit, no smaller
unit. Each school must have the claim to be considered in relation to
its special circumstances. The classifying of schools for some purposes
is necessary. But no absolutely rigid curriculum, not modified by its
own staff, should be permissible. Exactly the same principles apply,
with the proper modifications, to universities and to technical
colleges. When one considers in its length and in its breadth the
importance of this question of the education of a nation's young, the
broken lives, the defeated hopes, the national failures, which result
from the frivolous inertia with which it is treated, it is difficult to
restrain within oneself a savage rage. In the conditions of modern life
the rule is absolute, the race which does not value trained
intelligence is doomed. Not all your heroism, not all your social
charm, not all your wit, not all your victories on land or at sea, can
move back the finger of fate. To-day we maintain ourselves. To-morrow
science will have moved forward yet one more step, and there will be no
appeal from the judgment which will then be pronounced on the
uneducated.
We can be content with no less than the old summary of educational
ideal which has been current at any time from the dawn of our
civilization. The essence of education is that it be religious.
Pray, what is religious education?
A religious education is an education which inculcates duty and
reverence. Duty arises from our potential control over the course of
events. Where attainable knowledge could have changed the issue,
ignorance has the guilt of vice. And the foundation of reverence is
this perception, that the present holds within itself the complete sum
of existence, backwards and forwards, that whole amplitude of time,
which is eternity.
