The question is "Why shouldn't I go ahead and gratify my inclinations in any way that suits myself."
There are many reasons, some of which ought not to be very difficult for any one to understand. Broadly speaking, they are of three different 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.
