A child is able to take in the elements of Arithmetic at quite an early age. But in arithmetic we observe how very easily an intellectual element can be given the child too soon. Mathematics as such is alien to no man at any age. It arises in human nature; the operations of mathematics are not foreign to human faculty in the way letters are foreign in a succeeding civilisation. But it is exceedingly important that the child should be introduced to arithmetic and mathematics in the right way. And what this is can really only be decided by one who is enabled to overlook the whole of human life from a certain spiritual standpoint.
There are two things which in logic seem very far removed from one another: arithmetic and moral principles. It is not usual to hitch arithmetic on to moral principles because there seems no obvious logical connection between them. But it is apparent to one who looks at the matter, not logically, but livingly, that the child who has a right introduction to arithmetic will have quite a different feeling of moral responsibility from the child who has not. And — this may seem extremely paradoxical to you, but since I am speaking of realities and not of the illusions current in our age, I will not be afraid of seeming paradoxical, for in this age truth often seems paradoxical. — If, then, men had known how to permeate the soul with mathematics in the right way during these past years we should not now have bolshevism in Eastern Europe. This it is that one perceives: what forces connect the faculty used in arithmetic with the springs of morality in man.
