 Aristotle’s problem seemed to have arisen as a result of a theory of truth according to which, if a statement is true at a time, there has to be a state of the world at that time which makes it true. However, it has been argued that, if every meaningful statement is either true or false (once and for all), that alone implies fatalism; the very fact that a statement is true is enough to make what it describes unavoidable (Taylor 1983, Chapter 6). Suppose, for example, that John shaved one morning. Then the statement, “John shaved that morning”, is true. But, it is argued, that means that John did not have the power not to shave; because to have that power would be to have the power to render a true statement false. But no one has such a power; no one has ever succeeded in making a true statement false.
