But then there would be the blood all over the carpet and the floor." "There would not be any carpet on the floor in a store-room," says the boy.
"True," replies the mother; "you are right there; so that there would not be, after all, any great trouble about the blood.

But the man might not be killed outright, and it might be some time before the policemen would come, and we should see him all that time writhing and struggling in dreadful convulsions, which would fix horrid impressions upon our minds, that would haunt us for a long time afterwards." The mother could then go on to explain that, if the man had a wife and children, any one who had killed the husband and father would pity them as long as he lived, and could never see them or hear them spoken of without feeling pain, and even some degree of self-reproach; although, so far as the man himself was concerned, it might be that no injustice had been done.
After the excitement was over, too, he would begin to make excuses for the man, thinking that perhaps he was poor, and his children were suffering for bread, and it was on their account that he was tempted to steal, and this, though it would not justify, might in some degree palliate the act for which he was slain; or that he had been badly brought up, having never received any proper instruction, but had been trained and taught from his boyhood to pilfer and steal.
These and many analogous considerations might be presented to the child, going to show that, whatever the rule of strict justice in respect to the criminal may enjoin, it is not right to take the life of a wrong-doer merely to prevent the commission of a minor offense.

The law of the land recognizes this principle, and does not justify the taking of life except in extreme cases, such as those of imminent personal danger.
A friendly conversation of this kind, carried on, not in a spirit of antagonism to what the boy has said, but in the form of presenting information novel to him in respect to considerations which were to be taken into the account in addition to those which he had himself perceived, will have a great effect not only in modifying his opinion in this case, but also in impressing him with the general idea that, before adopting a decisive opinion on any subject, we must take care to acquaint ourselves not merely with the most direct and obvious relations of it, but must look farther into its bearings and results, so that our conclusion may have a solid foundation by reposing upon as many as possible of the considerations which ought really to affect it.

Thus, by avoiding all appearance of antagonism, we secure a ready reception for the truths we offer, and cultivate the reasoning powers at the same time.
_General Principles_.
The principles, then, which are meant to be illustrated and enforced in this chapter are these: 1.

That the mental faculties of children on which the exercise of judgment and of the power of reasoning depend are not among those which are the earliest developed, and they do not attain, in the first years of life, to such a degree of strength or maturity as to justify placing any serious reliance upon them for the conduct of life.
