History must be our deliverer not only from the undue influence of other times, but from the undue influence of our own, from the tyranny of environment and the pressures of the air we breathe. – Lord Acton (Cited in Eerdmans Handbook to the History of Christianity (Grand Rapids: Eerdmans, 1977), p. 2.
Wise men say, and not without reason, that whoever wishes to foresee the future must consult the past; for human events ever resemble those of preceding times. This arises from the fact that they are produced by men who have been, and ever will be, animated by the same passions, and thus they must necessarily have the same results. – Niccolo Machiavelli
