Because of experimental science we know a very large number of things about the natural world of which our predecessors were ignorant. In the great books we can observe the birth of science, applaud the development of the experimental technique, and celebrate the triumphs it has won. But we can also note the limitations of the method and mourn the errors that its misapplication has caused. We can distinguish the outlines of those great persistent problems that the method ... may never solve and find the clues to their solutions offered by other methods and other disciplines.
