A young man wrote to me the other day lamenting his ignorance and requesting me to tell

him
what books to read and what to do in order to become learned and wise. I sent him a civil
answer
and such advice as occurred to me. But I confess that the more I thought of the matter the
less
assured I felt of my competence for the task. I ceased to be flattered by the implied tribute to
my
omniscience, and felt rather like a person who gives up a third-class ticket after he has
ridden in
a first-class carriage might feel. I surveyed my title to this reputation for learning, and was
shocked at the poverty of my estate.
As I contrasted the mountain of things I didn't know with the molehill of things I did know, my
self-esteem shrank to zero. Why, my dear young sir, thought I, I cannot pay twopence in the
pound. I am nothing but the possessor of a widespread ignorance. Why should you come to
me
for a loan?
I begin with myself—this body of me that is carried about on a pair of cunningly devised stilts
and waves a couple of branches with five flexible twigs at the end of each, and is
surmounted by
a large round knob with wonderful little orifices, and glittering jewels, and a sort of mat for a
covering, and which utters strange noises and speaks and sings and laughs and cries.
Bless me, said I, what do I know about it? I am a mere bundle of mysteries in coat and
breeches.
I couldn't tell you where my epiglottis is or what it does without looking in a dictionary. I have
been told, but I always forget. I am little better than the boy in the class. "Where is the
diaphragm?" asked the teacher. "Please, sir, in North Staffordshire," said the boy. I may
laugh at
the boy, but any young medical student would laugh just as much at me if I told him honestly
what I do not know about the diaphragm. And when it comes to the ultimate mysteries of this
aggregation of atoms which we call the human body the medical student and, indeed, the
whole
Medical Faculty would be found to be nearly as ignorant as the boy was about the
diaphragm.
From myself I pass to all the phenomena of life, and wherever I turn I find myself exploring
whatCarlyle calls the "great, deep sea of Nescience on which we float like exhalations that
are
and then are not." I see Orion striding across the southern heavens, and feel the wonder and
the
majesty of that stupendous spectacle, but if I ask myself what I know about it I have no
answer.
And even the knowledge of the most learned astronomer only touches the fringe of the
immensity. What is beyond—beyond—beyond? His mind is balked, as mine is, almost at the
threshold of the mighty paradox of a universe which we can conceive neither as finite nor as
infinite, which is unthinkable as having limits and unthinkable as having no limits. As the
flowers come on in summer I always learn their names, but I know that I shall have to learn
them
again next year. And as to the mystery of their being, by what miracle they grow and
transmute
the secretions of the earth and air into life and beauty—why, my dear young sir, I am no
more
communicative than the needy knife-grinder. "Story? God bless you, I have none to tell, sir."
I cannot put my hand to anything outside my little routine without finding myself meddling
with
things I don't understand. I was digging in the garden just now and came upon a patch of
ground
with roots deep down. Some villainous pest, said I, some enemy of my carrots and potatoes.
Have at them! I felt like a knight charging to the rescue of innocence. I plunged the fork
deeper
and deeper and tore at the roots, and grew breathless and perspiring. Even now I ache with
the
agonies of that titanic combat. And the more I fought the more infinite became the
ramifications
of those roots. And so I called for the expert advice of the young person who was giving
some
candy to her bees in the orchard. She came, took a glance into the depths, and said: "Yes,
you are
pulling up that tree." And she pointed to an ivy-grown tree in the hedge a dozen yards away.
Did
I feel foolish, young sir? Of course I felt foolish, but not more foolish than I have felt on a
thousand other occasions. And you ask me for advice.
I recall one among many of these occasions for my chastening. When I was young I was
being
driven one day through a woodland country by an old fellow who kept an inn and let out a
pony
and chaise for hire. As we went along I made some remark about a tree by the wayside and
he
spoke of it as a poplar. "Not a poplar," said I with the easy assurance of youth, and I
described to
him for his information the characters of what I conceived to be the poplar. "Ah," he said,
"you
are thinking of the Lombardy poplar. That tree is the Egyptian poplar." And then he went on
to
tell me of a score of other poplars—their appearance, their habits, and their origins—quite
kindly
and without any knowledge of the withering blight that had fallen upon my cocksure
ignorance. I
found that he had spent his life in tree culture and had been forester to a Scotch duke. And I
had
explained to him what a poplar was like! But I think he did me good, and I often recall him to
mind when I feel disposed to give other people information that they possibly do not need.
And the books I haven't read, and the sciences I don't know, and the languages I don't
speak, and
the things I can't do—young man, if you knew all this you would be amazed. But it does not
make me unhappy. On the contrary I find myself growing cheerful in the contemplation of
these
vast undeveloped estates. I feel like a fellow who has inherited a continent and, so far, has
only
had time to cultivate a tiny corner of the inheritance. The rest I just wander through like a boy
in
wonderland. Some day I will know about all these things. I will develop all these immensities.
I
will search out all these mysteries. In my heart I know I shall do nothing of the sort. I know
that
when the curtain rings down I shall be digging the same tiny plot. But it is pleasant to dream
of
future conquests that you won't make. And, after all, aren't we all allotment holders of the
mind, cultivating our own little patch and
surrounded by the wonderland of the unknown? Even the most learned of us is ignorant
when his
knowledge is measured by the infinite sum of things. And the riches of knowledge
themselves
are much more widely diffused than we are apt to think. There are few people who are not
better
informed about something than we are, who have not gathered their own peculiar sheaf of
wisdom or knowledge in this vast harvest field of experience. That is at once a comfortable
and a
humbling thought. It checks a too soaring vanity on the one hand and a too tragic abasement
on
the other. The fund of knowledge is a collective sum. No one has all the items, nor a fraction
of
the items, and there are few of us so poor as not to have some. If I were to walk out into the
street now I fancy I should not meet a soul, man or woman, who could not fill in some blank
of
my mind. And I think—for I must not let humility go too far—I think I could fill some blank in
theirs. Our carrying capacity varies infinitely, but we all carry something, and it differs from
the
store of any one else on earth. And, moreover, the mere knowledge of things is not
necessary to
their enjoyment, nor necessary even to wisdom. There are things that every ploughboy
knows
today which were hidden from Plato and Caesar and Dante, but the ploughboy is not wiser
than
they. Sir Thomas Browne, in his book on Vulgar Errors, declared that the idea that the earth
went
round the sun was too foolish to be controverted. I know better, but that doesn't make me a
wiser
man than Browne. Wisdom does not depend on these things. I suppose that, on the whole,
Lincoln was the wisest and most fundamentally sane man who ever took a great part in the
affairs of this planet. Yet compared with the average undergraduate he was utterly
unlearned.
Do not, my young friend, suppose I am decrying your eagerness to know. Learn all you can,
my
boy, about this wonderful caravan on which we make our annual tour round the sun, and on
which we quarrel and fight with such crazy ferocity as we go. But at the end of all your
learning
you will be astonished at how little you know, and will rejoice that the pleasure of living is in
healthy feeling rather than in the accumulation of facts. There was a good deal of truth in
that
saying of Savonarola that "a little old woman who kept the faith knew more than Plato or
Aristotle.”
