In the previous chapter, a number of paradoxes concerning time were brought out — deeper problems may yet exist! Here we take up the study of time in Newtonian physics. In the absence of an independent defmition of force and an independent measure of time, Newton’s laws of motion, by themselves, fail to be falsifiable, and hence lack physical content. However, the combination of the laws of motion and the law of gravitation leads to refutable consequences and good physics, because both unknowns may be eliminated. We conclude with a discussion of Laplace’s demon, and point out that standard ways to exorcise the demon lead, in fact, to unpleasant time-symmetric contingents.
