We inherit the products of the thought of other men. We inherit the wheel. We
make a cart. The cart becomes an automobile. The automobile becomes an
airplane. But all through the process what we receive from others is only the
end product of their thinking. The moving force is the creative faculty which
takes this product as material, uses it and originates the next step. This
creative faculty cannot be given or received, shared or borrowed. It belongs to
single, individual men. That which it creates is the property of the creator.
Men learn from one another. But all learning is only the exchange of material.
No man can give another the capacity to think. Yet that capacity is our only
means of survival.
