 A major part of Augustine’s early education consisted in the study of Cicero’s writings. He was thus closely acquainted with Academic skepticism (Cicero was one kind of Academic skeptic). Augustine sees the force of ancient skeptical strategies. Even though he does not become a skeptic, he integrates distinctively skeptical moves into his thought. This has a long-standing effect on the history of theology and science. For example, Galileo Galilei is able to cite Augustine when he defends himself against the charge that his physics is in opposition to the Bible (Letter to the Grand Duchess, in Drake 1957). Augustine supplies arguments to the effect that we should keep an open mind. Both our physical theories and our interpretations of the Bible are likely to evolve. This idea figures importantly in Pyrrhonism. Past experience tells us that, on every given issue, someone eventually came up with a new argument. Accordingly, even if the skeptics cannot find an objection to a given claim right now, they expect that in the future, a conflicting view will be formulated.
