We have gained balance of thought when we can see things not only from our own point of view, with the ideas and the feelings in which we are trained, but from all sides. The one-sided person has no balance. Suppose a man is very patriotic and sees everything from the point of view of patriotism, and he goes to a shop and demands that the shop-keeper sells him some things, for a patriotic purpose, for a very low price. But the shop-keeper may be a poor man, and even for a patriotic purpose he cannot sell his wares at that price. Then too he is a shop-keeper and he thinks of his trade; he cannot be expected to see with the other's patriotic eyes. One person thinks only of patriotism; another only of trade; and a third, who is a musician, says, 'They are crazy; music alone matters!' The poet says, 'Poetry is the only thing in the world'. Each of them thinks solely of that with which he is himself engaged. Thus the pious person may exaggerate his piety so much that there is nothing left in him but piety, which at last becomes hypocrisy.
