But why every Tom, Dick and Harry should have the why and wherefore of the universe rammed into him, and should be allowed to draw the conclusion hence that he is the ideal person and responsible for the universe, I don't know.

It is a lie anyway--for neither the whys nor the wherefores are his own, and he is but a parrot with his nut of a universe.
Why should we cram the mind of a child with facts that have nothing to do with his own experiences, and have no relation to his own dynamic activity?
Let us realize that every extraneous idea effectually introduced into a man's mind is a direct obstruction of his dynamic activity.

Every idea which is introduced from outside into a man's mind, and which does not correspond to his own dynamic nature, is a fatal stumbling-block for that man: is a cause of arrest for his true individual activity, and a derangement to his psychic being.
For instance, if I teach a man the idea that all men are equal.

Now this idea has no foundation in experience, but is logically deduced from certain ethical or philosophic principles.

But there is a disease of idealism in the world, and we all are born with it.
