第一套
What We Know
About Language
Many
things
about
language
are
a
mystery
and will
remain
so.
However, we
now
do
know
something about it. First, we know that
all human beings have a language of some sort. No
human
race anywhere on earth is so
backward that it has no language of its own at
all. Second , there is
no such thing as
a primitive language. There are many people whose
cultures are undeveloped but
the
languages
they
speak
are
by
no means
primitive.
In
all
the
languages
existing
in
the world
today,
there
are
complexities
that must
have
been
developed
for
years.
Third, we
know
that
all
languages are perfectly adequate. Each
is a perfect means of expressing its culture. And
finally, we
know
that
language
changes
over
time, which
is
natural
and
normal
if
a
language
is
to
survive.
The language which
remains unchanged is nothing but dead.
