The significant contribution of empiricism was not the eradication of certainty, but the eradication of infallibility as a criterion of certainty. And this shift from infallibilism to fallibilism has profound consequences not only for toleration, but also for the subordination of faith to reason and theology to philosophy.

It cannot be emphasized too strongly that Christianity has a vested interest in human misery. Christianity, perhaps more than any religion before or since, capitalized on human suffering; and it was enormously successful in insuring its own existence through the perpetuation of human suffering.

A willingness to engage in the give and take of argument displays a commitment to cognitive egalitarianism - the proposition that all people should be treated as intellectual equals, and that no individual can legitimately claim a privileged immunity from the burden of proof.

The argument from design is ultimately an appeal to miraculous causes, i.e., causes that do not, and cannot, occur in the natural course of events. This is why an explanation via design is not a legitimate alternative to scientific and other naturalistic modes of explanation. To refer to a miraculous cause is to refer to something that is inherently unknowable, and this sanctuary of ignorance explains nothing at all. However much it may soothe the imagination of the ignorant, it does nothing to satisfy the understanding of a rational person.

Christianity cannot erase man's need for pleasure, nor can it eradicate the various sources of pleasure. What it can do, however, and what it has been extremely effective in accomplishing, is to inculcate guilt in connection with pleasure. The pursuit of pleasure, when accompanied by guilt, becomes a means of perpetuating chronic guilt, and this serves to reinforce one's dependence on God.

The leap of faith is a strategic impasse that confronts every Christian in search of converts; and, as he sees the matter, there is no wrong way to become a Christian. It is the end that is importnat, not the means; it does not matter why you believe, so long as you believe. For the philosopher, in contrast, the paramount issue is the justification of belief, not the fact of belief itself.

The significant contribution of empiricism was not the eradication of certainty, but the eradication of infallibility as a criterion of certainty. And this shift from infallibilism to fallibilism has profound consequences not only for toleration, but also for the subordination of faith to reason and theology to philosophy.
