Suppose you are very patriotic and see everything from the point of view of patriotism, and you go to an ironmonger and demand that he should sell you some things at a certain price. But the ironmonger is a poor man and, even for a patriotic purpose, he cannot sell the things at that price. After all he is an ironmonger and he thinks of his trade; he cannot be expected to see with your patriotic eyes. One person thinks only of patriotism; another says, "God save the trade." A third, who is a musician, says, "They are mad, crazy! Music is the only thing that matters." The poet says, "Poetry is the only thing in the world." Each thinks only of that in which he is active. A pious person exaggerates his piety so much that there is nothing in him but piety, which at last becomes hypocrisy.
