THE
IMMUTABILITY OF HUMAN NATURE
Dear Dr. Adler,
Realists or cynics often respond to plans to
establish world peace or social justice with
the remark, "You can't change human nature."
What are the views of various schools of thought
on whether human nature can be changed or
not? If human nature is unchangeable, does
that mean that social progress is
impossible?
M.P.R.
Dear M. P. R.,
Western thought gives three main answers to the
question about the constancy or immutability of
human nature.
The first is the traditional view that men are
essentially the same generation after generation.
According to this view, the set of physical and
mental characteristics which constitute the
specific nature of man have not changed and will
not vary as long as man is man and not another kind
of creature. The reason human behavior always runs
true to form is that it is determined by unchanging
properties of human nature -- the same mental
faculties, the same emotional makeup. The
individual may modify his inherited equipment in
the course of his lifetime, but each individual
starts out with the same basic equipment.
The second view follows from the evolutionary
hypothesis which has dominated Western thought
since the nineteenth century. According to this
view, human nature has undergone an evolutionary
development during the last eighty thousand years.
The genetic constitution of man has been altered,
and this has resulted in perceptible changes in
man's body and probably also in his mind. Some
exponents of this view believe that certain of
these changes have taken place in the relatively
short period of recorded human history and are
still going on.
The third view is the historical or sociological
view that what man is varies with the culture and
society in which he lives. Some protagonists of
this view believe that man's nature is formed by
his social environment, and that man, in different
epochs, is "the product of his times." Others
believe that he can fashion his society and himself
according to his will -- "man makes himself."
Contemporary existentialist philosophy, with its
emphasis on man's power to create himself, has an
obvious affinity with this school of thought.
Such views usually proclaim that man has no
antecedent or independent nature, fixed for all
time. Man has only a history and a constantly
changing existence. This, by the way, is the
central thesis in the Marxist theory of man.
There is a certain confusion about the saying,
"You can't change human nature." It may simply
express the traditional view that man, like any
other species, has a nature that remains
essentially the same as long as the species itself
endures. Or it may express the conservative,
pessimistic view that certain social evils, such as
war, slavery, and poverty, are irremediable. Those
who are hopeless about reforming these things blame
their despair on human nature. The late John Dewey
argued against such inferences in his Human
Nature and Conduct. He held that social evils
can be eliminated by giving a new pattern to basic
human impulses, and by turning human activity into
new directions.
On this point I tend to agree with John Dewey. I
do not believe that age-old social evils such as
war spring from something inherent in human nature.
On the other hand, I agree with those who say that
all the progress man can make comes from improving
his institutions, not from perfecting his nature.
It is society, not man, that is perfectible within
certain limits. These limits are set by the
unalterable limitations of man's nature.
For example, to say that man is by nature social
means that man will always need to live in society.
To say, furthermore, as Alexander Hamilton did,
that men are not angels, is to say that human
societies will always need government. In other
words, man is by nature unfit for anarchy, and this
will always be so, as long as man lives on earth.
He can no more dispense with government than he can
subsist without food or fly without mechanical
means to carry him.
THE
DIFFERENCE BETWEEN MEN AND ANIMALS
Dear Dr. Adler,
Is there any basic difference between men and
animals, or is man an animal like all the
others? Some people say that man is the only
creature that can think and learn. But I don't
regard this as a real distinction, since
biologists and psychologists have demonstrated
that animals can construct things and solve
problems. I have known some very intelligent
dogs and some very thoughtless human beings. What
is the essential difference between man and the
animals?
A.M.P.
Dear A. M. P.,
Until comparatively recent times, few
philosophers doubted that man was essentially
different from all other animals. In the great
tradition of Western thought, from Plato right down
to the nineteenth century, it was almost
universally held that man and man alone is a
rational animal. This philosophical view of man's
distinctive nature accords with the Biblical view
that man and man alone is created in the image of
God -- a person, not a thing.
Since the time of Darwin, the opposite view has
come to prevail, not only among scientists but
among the educated classes generally. The Darwinian
theory of man's origin, as you know, is that man
and the anthropoid apes have descended from a
common ancestral form; and along with this view of
man's evolutionary origin goes the view that man
and the higher mammals differ only in degree. Thus,
for example, instead of regarding man alone as
rational, the evolutionists find the same kind of
intelligence in man and other animals. Man simply
has more of it.
You say in your letter that you think the
traditional arguments for man's distinctive nature
are weak, because animals as well as men can
reason, because animals as well as men can make
things, etc. Let me answer your question by
defending the traditional point of view about man
as a very special creature.
The strongest evidence that men have certain
powers which no other animals possess in any degree
whatsoever consists in the things which men can do
but which other animals cannot do at all. One such
indication is man's power of making things.
I know that bees make hives, birds make nests,
and beavers make dams. But such productions are
entirely instinctive on their part. A given species
of bird makes its nests in the same way generation
after generation. This shows that the nest is a
product of instinct not of art, which involves
reason and free will. In making houses, bridges, or
any other of their artifacts, men invent and
select. They are truly artists, as animals are
not.
In addition, only men build machines which are
themselves productive. Other animals may use rough
tools, but no other animal makes a die press which
stamps out an indefinite number of a product when
the raw materials are fed into it. This is another
indication of man's special power as a maker of
things.
You say that other animals can reason. In my
opinion it is more correct to say that other
animals can solve problems when they are confronted
by the biological urgency of finding a way of
getting what they need. All so-called "thinking" by
animals is on this level. But no animal ever sits
down to think, the way a philosopher or a
mathematician does when he has no biologically
urgent need to do so.
The fact that human thinking is discursive and
involves language is another indication that it is
quite different from animal problemsolving.
Animals, of course, do make sounds and communicate
their emotions or impulses to one another. But no
animal communicates thought; no animal ever utters
a sentence which asserts something to be true or
false. Only a rational animal can do that.
I could go on and give you many other items of
evidence that man has certain powers which no other
animal possesses in the least degree. But I shall
content myself with one more fact.
Man is the only animal with an historical
development. Other animals may change in their
biological constitution over the course of hundreds
of thousands of generations; but such changes
result entirely from changes in the germ plasm,
which is the only thing that is transmitted from
one generation to another. Men transmit ideas and
institutions, a whole tradition of culture, from
one generation to another, and it is this which
accounts for the history of the human race.
In my opinion the empirical evidence is
overwhelmingly in favor of the view that men are
essentially different in kind from the brutes. Like
the brutes, they, too, are animals. But unlike
them, men are rational. This, of course, if true,
would require us to reject Darwin's theory of man's
evolutionary origin. But theories after all must be
made to fit the facts, not facts theories.
THE
PURPOSE OF LIFE
Dear Dr. Adler,
It seems to me that the most important
question of all is the purpose of life. What
are we doing here on earth? What is our destiny?
How do various thinkers approach this most urgent
and baffling of all questions?
C. L. V.
Dear C. L. V.,
Let us begin by asking the purpose of the
question about the purpose of life. What do men
have in mind when they ask this question? Asking it
is a peculiarly human phenomenon. Other creatures
just exist and go on unquestioningly to pursue
their natural ends -- to be a tree or a bird or a
stone. It is man's peculiar misery or glory that he
perennially poses the question of the purpose of
his own existence.
What, then, are men who ask this question trying
to discover? Are they asking about the destiny
appointed by God for man to achieve through his
earthly existence? Does man have an ultimate goal
beyond the sphere of his temporal experience? And
if so, what must he do to attain it? The Christian
doctrine of the Kingdom of God as man's ultimate
destiny is one of the answers to the question.
Or are men asking whether human life can be made
significant on earth by achieving all the
perfections of which it is capable? In the
philosophy of Aristotle, each kind of creature
tends toward the perfection of its own nature.
Thus, for man, the goal -- the purpose -- of life
is to achieve the virtues that constitute
happiness.
As against these theological and philosophical
ideas of human destiny, our question may arise from
a conviction of the purposelessness of the physical
universe as a whole. We look out on the world
around us and see nothing but a whirl of atoms in a
meaningless void. Whether we see the physical world
as chaotic and "chancy" or as an orderly cosmos,
human life may still seem meaningless and
valueless. The pattern of material events is no
answer to the questing human heart and mind. All of
science remains silent when man asks, "What am I
doing here? Where did I come from? Where am I
going? What is the purpose of my life?"
Many modern thinkers, faced with these urgent
and disturbing questions, reject the traditional
theological and philosophical views of the purpose
and meaning of human life. They assert that men can
and must set their own goals, and find meaning in
the creation and transformation of their own
nature. In their view, a man who is truly human
must live for some transcendent goal that he sets
himself. If he does not do this, he must be
engulfed in overwhelming despair at the
meaninglessness of life.
I think we will all agree that the question is
urgent and that it demands an answer and a life
which is in accord with the answer. On the other
hand, to answer the question requires us to take a
comprehensive view of God, the universe, and man.
An understanding of man and his nature is
necessary, but it is not enough for a solution to
the problem of the meaning of human existence. We
must also understand the place of man in the
universe and in relation to all the beings that
there are. And we must see him in relation to the
ultimate power that governs the universe and all
that is in it. Man is not alone in the universe,
and we cannot understand him apart from the rest of
things.
This sounds like a long-term program and it is
-- as long as life itself. It requires the study of
theology and metaphysics, as well as of psychology
and ethics. It requires the experience and wisdom
which can be acquired only after much living and
much effort.
This is what is so disturbing about the
question. It is urgent, it calls for an immediate
answer, and yet it demands the patient and careful
reflection of a lifetime. But "that's life," as the
popular saying has it. It has never been easy to be
a human being.
THE
ELEMENT OF CHANCE IN HUMAN LIFE
Dear Dr. Adler,
Men who have achieved prominence often admit
that luck or chance has had a lot to do with
their success. And we all know that there is
bad luck as well as good luck. Chance encounters
often determine lifetime friendships and
marriages. The course of history may be
changed by chance events. The chance downing of
a photo-reconnaissance plane may break up a
"summit" conference prepared over many
years. What do the great thinkers have to say
about the role of chance or luck in human
affairs?
S. T.
Dear S. T.,
The great thinkers of the past disagree a lot
about what chance is and even whether there is such
a thing. But one thing they do agree about: we
can't be sure of our luck, nor can we control it.
The "chancy" is what's uncertain and
unpredictable.
The ancients contrast what happens by chance
with what happens naturally, necessarily, more or
less regularly, or as the result of conscious human
purpose. Men, since they are by nature mortal,
necessarily die. If the sun shines on a pool of
water, it normally evaporates. These things do not
happen by chance; they happen because of the very
natures of the things involved. Nor is my going to
the store a matter of chance if I go there for a
deliberate purpose. But if I happen to meet a
friend there by the sheer coincidence that
our paths cross at a given time and place, that
meeting, according to Aristotle, is something which
happened by chance.
The ancients also call chance in human affairs
"fortune," which has the same root as the word
"fortuitous." They consider such things as wealth,
fame, honor, and power to be goods of fortune.
Having or not having them is largely a matter of
chance, not of deliberate choice as in the case of
such goods as knowledge and virtue. Aristotle,
however, thinks that the goods of fortune are
important for human happiness. The Stoics, on the
other hand, consider it noble to be indifferent
toward things beyond our control.
Many thinkers deny that there really is any such
thing as chance. What we call chance, they say, is
merely an expression of our ignorance of the causes
of events. When we don't know why a thing happens,
we ascribe it to chance. Spinoza maintains that
nothing happens by chance, that all things are
determined to be as they are. Most Christian
theologians, with their notion of a divine
providence that affects even the fall of a sparrow,
agree with Augustine that "nothing happens at
random in the world." Everything, even what appears
to be a matter of chance, has been willed by
God.
William James, who shudders at the idea of
Spinoza's completely determined universe, holds
that there are certain ultimate choices in human
life that we cannot decide on rational grounds
alone. Where such choices are about matters that
concern us vitally, he feels that we must decide
one way or the other and take the risk of being
wrong. The alternative, of course, is to wait until
all the returns are in, when a rationally certain
judgment would be possible. But, says James, on
such questions all the evidence never does come in;
indeed, it does not come in at all unless you take
a chance.
Economists, those practitioners of the "dismal"
science, are rather sober-sided about such things
and take a gloomy view of betting. John Maynard
Keynes in his Treatise on Probability
concludes that it is rational and ethical to avoid
great risks and to be guided by calculated
probability. He advises us not to gamble, at cards
or the Stock Exchange, unless we can afford to lose
a lot of money.
Adam Smith in The Wealth of Nations is
even more pessimistic about taking chances. He
points out, in regard to lotteries, that the
percentage is always in favor of the house.
- The world neither ever saw, nor ever will
see, a perfectly fair lottery; or one in which
the whole gain compensated the whole loss;
because the undertaker could make nothing by it.
. . . There is not a more certain proposition in
mathematics than that the more tickets you
adventure upon, the more likely you are to be a
loser. Adventure upon all the tickets in the
lottery, and you lose for certain.
Adam Smith does not say, "You can't win." One
ticket, or a piece of it, on the winning horse in
the Irish Sweepstakes may bring in a considerable
sum. But the more you try to make your luck
certain, the more likely you are to suffer net
loss. I wonder how much all the tickets in the
Irish Sweepstakes would cost.
