kinds--First, experience; second, affection; third, faith.

Let us examine them in order, in a simple, leisurely way, and try to
make clear the essence of each.

What does the question of experience lead to and imply?

First, there is one's own experience; then there is the experience of
other people.

Our own experience teaches us very quickly that we often have impulses
which it would be a mistake to obey. If you feel like pulling a strange
dog's tail and the dog turns on you and bites your hand and the wound
has to be cauterized, and you have to go through a lot of pain and
trouble and fear of hydrophobia, one lesson will probably be enough for
you.

Suppose you are overheated and feel like sitting in a draft and letting
the cool air blow on you, and this is followed by a heavy cold which
lays you up for a week or two?

Or suppose you are on top of a tall building and feel a strong impulse
to jump out and go sailing through the air? Many people have this
impulse, but they have previously had enough experience to know what
happens to people who fall from high places.

The number of such examples might be multiplied indefinitely, but enough
has been suggested to indicate the principle. It is quite obvious and
childishly simple--the lessons taught to each and every one of us by our
own experience.

Now let us follow this path a step further. It is quite possible for you
to have impulses and inclinations to do things which might cause you
irreparable harm. The consequences of these things are not something
that you can remember and foresee, because in your own experience they
have not occurred before. If you stick to your idea of obeying no one
but yourself and of being unafraid to do what you want, the lesson in
store for you may come too late.

Certain impulses of yours, if followed, may cause death. Others may
cause permanent injury to yourself, or irreparable harm to others.

A little boy seeing an automobile coming along the road sometimes has an
impulse to run across the road in front of the automobile, for the fun
and excitement of it. If you are a boy and feel like it, why shouldn't
you?

You have never tripped and fallen in front of an automobile--you have
never misjudged the speed of it and been struck and killed that way.

You have never seen any other boy killed that way. There is nothing in
your own experience to deter you.

If the automobile happens to hit you, you will have acquired experie
