Some children have the reasoning faculty developed in them and others have not. But this is a faculty upon which the future of the child depends, upon which its whole life depends. Where the reasoning faculty is not developed there is always a danger for its life. It can be easily cultivated in the child by asking questions for and against everything: if it must be, why it must be; and if it must not be, why it must not be; and sometimes quite the contrary question. When a child says, "This is right", it must be asked why it is right; if the child says, "This is wrong", it must be asked why it is wrong. The guardian must take the same attitude that the child has, always asking why, instead of letting the child ask why. The guardian must become a child and ask why of everything; and in this way reasoning is developed. Any child that shows the quality of reasoning has the promise of a wonderful future before it.
