John Dewey was a student of the pragmatic philosophers Pierce and James. He was a mathematician. Pragmatism is based upon the philosophy of science. It seeks to find undoubtable truths. Like a scientist, the pragmatists try to disprove a fact or theory until there is no doubt. The pragmatist, however, believes there are no totally undoubtable truths, because truth can only be obtained by the future results of current events. Therefore, we never know if something is true until it proves to be so. What is accepted as a truth today, may be proven false in the future. For instance, it was at one time believed the world was flat, and the planets revolved around the earth. This was considered fact. However, when it was proven false, new ideas were accepted as facts, and will be accepted as fact until proven they are proven false. Pragmatic truths, therefore, are the future results of current events. There are no pragmatic truths or undoubtable facts, only probable truths based on empirical experience.

 John Dewey reflected upon the traditional philosophic works and saw that they were out of tune with a world that is constantly changing. The goal of traditional philosophy was to discover concrete truths from which to build a philosophical metaphysics. Dewey realized that truth is dependent upon many different factors (instruments), and changes according to those factors. Dewey asks is philosophy the search for truth or the best way to find the truth? He defends the idea that concrete truth cannot be obtained, therefore; the best thing to do is find what is the true meaning according to the values we place upon it our current culture. Therefore, in the 14th Century the idea that the world was flat and the sun, moon, and planets was true, because according to the facts available to that culture it was the best theory they could muster. Dewey recognizes the importance of the context, situation and problem we are involved with and uses reflection and criticism to dispute former philosophies and cure them of any ills they have; specifically, there use of selective emphasis. In "Dewey's Metaphysics," Richard Rorty accuses John Dewey of the greatest sin a philosopher can make. Dewey, according to Rorty, is guilty of his own criticism. Dewey's goal of developing a Naturalistic Metaphysics, or a god's eye view of the world, places a precondition, a selective emphasis on his philosophy which is the same mistake made by the philosophers he criticized.

 If we apply Dewey to Dewey we find that his naturalistic metaphysics does not wash. Rorty is correct he makes the same mistakes he criticizes. How can there be a definitive naturalistic metaphysics of experience, if the world is constantly in flux and truth is only relevant to the values and meanings that currently define it? Will the naturalistic metaphysics of experience change with history like values and meanings? Will it change the different experiences of each individual? If the door no longer closes, but did close before, it still closed previously. The first experience does not change. It still remains true. Rorty explains:

 . . .no man can serve both Locke and Hegel. Nobody can claim to offer an "empirical" account of something called "the inclusive integrity of 'experience,'" nor take this "integrated unity as the starting point of philosophic thought," if he also agrees with Hegel that the starting point of philosophic thought is bound to be the dialectical situation in which one finds oneself caught in one's own time.
