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. […]
[…] in addition we do not go from the parts to arrive at the sum, but we start with the sum and proceed to the parts. Thus to get a living understanding of addition we start with the whole and proceed to the addenda, to the parts. For addition is concerned essentially with the sum and its parts, the members which are contained, in one way or another, within the sum.
In this way we get the child to enter into life with the ability to grasp a whole, not always to proceed from the less to the greater. And this has an extraordinarily strong influence upon the child’s whole soul and mind. When a child has acquired the habit of adding things together we get a disposition which tends to be desirous and craving. In proceeding from the whole to the parts, and in treating multiplication similarly, the child has less tendency to acquisitiveness, rather it tends to develop what, in the Platonic sense, the noblest sense of the word, can be called considerateness, moderation. And one’s moral likes and dislikes are intimately bound up with the manner in which one has learned to deal with number. At first sight there seems to be no logical connection between the treatment of numbers and moral ideas, so little indeed that one who will only regard things from the intellectual point of view, may well laugh at the idea of any connection. It may seem to him absurd. We can also well understand that people may laugh at the idea of proceeding in addition from the sum instead of from the parts. But when one sees the true connections in life one knows that things which are logically most remote are often in reality exceedingly near.
