The words of Anaximander quoted in the first chapter of this book invited us to think of the world “according to the order of time.” If we do not assume a priori that we know what the order of time is—if we do not, that is, presuppose that it is the linear and universal order that we are accustomed to—Anaximander’s exhortation remains valid: we understand the world by studying change, not by studying things. Those who have neglected this good advice have paid a heavy price for it. Two of the greats who fell into this error were Plato and Kepler, both curiously seduced by the same mathematics.
