Once upon a time there was a young prince who believed in all things but three. He did not believe in princesses, he did not believe in islands, he did not believe in God. His father, the king, told him that such things did not exist. As there were no princesses or islands in his father's domains, and no sign of God, the young prince believed his father.But then, one day, the prince ran away from his palace. He came to the next land. There, to his astonishment, from every coast he saw islands, and on these islands, strange and troubling creatures whom he dared not name. As he was searching for a boat, a man in full evening dress approached him along the shore.Are those real islands?' asked the young prince.Of course they are real islands,' said the man in evening dress.And those strange and troubling creatures?'They are all genuine and authentic princesses.'Then God must exist!' cried the prince.I am God,' replied the man in full evening dress, with a bow.The young prince returned home as quickly as he could.So you are back,' said the father, the king.I have seen islands, I have seen princesses, I have seen God,' said the prince reproachfully. The king was unmoved.Neither real islands, nor real princesses, I have seen God,' said the prince reproachfully.The king was unmoved.Neither real islands, nor real princesses, nor a real God exist.'I saw them!'Tell me how God was dressed.'God was in full evening dress.'Were the sleeves of his coat rolled back?'The prince remembered that they had been. The king smiled.That is the uniform of a magician. You have been deceived.'At this, the prince returned to the next land, and went to the same shore, where once again he came upon the man in full evening dress.My father the king has told me who you are,' said the young prince indignantly. 'You deceived me last time, but not again. Now I know that those are not real islands and real princesses, because you are a magician.'The man on the shore smiled.It is you who are deceived, my boy. In your father's kingdom there are many islands and many princesses. But you are under your father's spell, so you cannot see them.'The prince pensively returned home. When he saw his father, he looked him in the eyes.Father, is it true that you are not a real king, but only a magician?'The king smiled, and rolled back his sleeves.Yes, my son, I am only a magician.'Then the man on the shore was God.'The man on the shore was another magician.'I must know the real truth, the truth beyond magic.'There is no truth beyond magic,' said the king.The prince was full of sadness.He said, 'I will kill myself.'The king by magic caused death to appear. Death stood in the door and beckoned to the prince. The prince shuddered. He remembered the beautiful but unreal islands and the unreal but beautiful princesses.Very well,' he said. 'I can bear it.'You see, my son,' said the king, 'you too now begin to be a magician.
Truth, says instrumentalism, is what works out, that which does what you expect it to do. The judgment is true when you can "bank" on it and not be disappointed. If, when you predict, or when you follow the lead of your idea or plan, it brings you to the ends sought for in the beginning, your judgment is true. It does not consist in agreement of ideas, or the agreement of ideas with an outside reality; neither is it an eternal something which always is, but it is a name given to ways of thinking which get the thinker where he started. As a railroad ticket is a "true" one when it lands the passenger at the station he sought, so is an idea "true," not when it agrees with something outside, but when it gets the thinker successfully to the end of his intellectual journey. Truth, reality, ideas and judgments are not things that stand out eternally "there," whether in the skies above or in the earth beneath; but they are names used to characterize certain vital stages in a process which is ever going on, the process of creation, of evolution. In that process we may speak of reality, this being valuable for our purposes; again, we may speak of truth; later, of ideas; and still again, of judgments; but because we talk about them we should not delude ourselves into thinking we can handle them as something eternally existing as we handle a specimen under the glass. Such a conception of truth and reality, the instrumentalist believes, is in harmony with the general nature of progress. He fails to see how progress, genuine creation, can occur on any other theory on theories of finality, fixity, and authority; but he believes that the idea of creation which we have sketched here gives man a vote in the affairs of the universe, renders him a citizen of the world to aid in the creation of valuable objects in the nature of institutions and principles, encourages him to attempt things "unattempted yet in prose or rhyme," inspires him to the creation of "more stately mansions," and to the forsaking of his "low vaulted past." He believes that the days of authority are over, whether in religion, in rulership, in science, or in philosophy; and he offers this dynamic universe as a challenge to the volition and intelligence of man, a universe to be won or lost at man’s option, a universe not to fall down before and worship as the slave before his master, the subject before his king, the scientist before his principle, the philosopher before his system, but a universe to be controlled, directed, and recreated by man’s intelligence.
