+6.+ Our feelings and desires are not the only things we wish to
communicate. The natural language satisfies a child for a time, but as
the child grows he begins to _think_, then he feels the need of a more
effective means of expressing himself. You can express your feelings to
a certain extent by the natural language. You can make one know that you
are glad by the expression of the face, the attitude of the body or the
tone of the voice. But could you make anyone understand _why_ you are
glad, by these signs and gestures?
+7.+ To express thoughts and ideas, man had to devise another sort of
language. So the language of _words_ grew up out of the need to
communicate ideas to other people. As man's ability to think grew, so
his language grew. At first, this language was only a spoken language.
The ideas of one generation were handed down to the next by the spoken
word. Gradually a crude form of writing was invented from which our
written language has developed. This has made it possible to put the
wisdom of the ages into books for the benefit of the world.
+8.+ +Hence, language is the means of expressing thought and feeling.+
It has grown out of our need for expression.
+A word is a symbol of an idea.+ It is a sound or combination of sounds
which we use to represent an idea. The use of words makes it possible
for us to readily convey our thoughts to other people.
Through the medium of words we are able to communicate to others our
thoughts, not only of the external world about us, but also of the
mental world in which we live. We can tell of our loves, our hates, our
dreams and our ideals. Animals find the natural language of looks and
tones and gestures sufficient because they live almost wholly upon the
physical plane. But man lives in a mental world as well as in a physical
one, and must have a spoken and written language by which to express his
thoughts.
