An account of the resurgence of philosophical theism in our time, including a brief survey of prominent anti-theistic arguments such as the presumption of atheism, the incoherence of theism, and the problem of evil, along with a defense of theistic arguments like the contingency argument, the cosmological argument, the teleological argument, and the moral argument.

Introduction
The last half-century has witnessed a veritable revolution in Anglo-American philosophy. In a recent retrospective, the eminent Princeton philosopher Paul Benacerraf recalls what it was like doing philosophy at Princeton during the 1950s and '60s. The overwhelmingly dominant mode of thinking was scientific naturalism. Metaphysics had been vanquished, expelled from philosophy like an unclean leper. Any problem that could not be addressed by science was simply dismissed as a pseudo-problem. Verificationism reigned triumphantly over the emerging science of philosophy. "This new enlightenment would put the old metaphysical views and attitudes to rest and replace them with the new mode of doing philosophy."1
The collapse of the Verificationism was undoubtedly the most important philosophical event of the twentieth century. Its demise meant a resurgence of metaphysics, along with other traditional problems of philosophy which Verificationism had suppressed. Accompanying this resurgence has come something new and altogether unanticipated: a renaissance in Christian philosophy.
The face of Anglo-American philosophy has been transformed as a result. Theism is on the rise; atheism is on the decline.2 Atheism, though perhaps still the dominant viewpoint at the American university, is a philosophy in retreat. In a recent article in the secularist journal Philo Quentin Smith laments what he calls "the desecularization of academia that evolved in philosophy departments since the late 1960s." He complains,
Naturalists passively watched as realist versions of theism. . . began to sweep through the philosophical community, until today perhaps one-quarter or one-third of philosophy professors are theists, with most being orthodox Christians . . . . in philosophy, it became, almost overnight, 'academically respectable' to argue for theism, making philosophy a favored field of entry for the most intelligent and talented theists entering academia today.3
Smith concludes, "God is not 'dead' in academia; he returned to life in the late 1960s and is now alive and well in his last academic stronghold, philosophy departments."4
As vanguards of a new philosophical paradigm, theistic philosophers have freely issued various critiques of atheism. In so short a space as this entry it is impossible to do little more than sketch some of them and to provide direction for further reading. These critiques could be grouped under two basic heads: (1) There are no cogent arguments on behalf of atheism, and (2) There are cogent arguments on behalf of theism.
No Cogent Arguments on behalf of Atheism
Presumption of Atheism. Theists have complained that the usual arguments against God's existence do not pass philosophical muster. One of the most commonly proffered justifications of atheism has been the so-called presumption of atheism. At face value, this is the claim that in the absence of evidence for the existence of God, we should presume that God does not exist. So understood, such an alleged presumption seems to conflate atheism with agnosticism. When one looks more closely at how protagonists of the presumption of atheism use the term "atheist," however, one discovers that they are sometimes re-defining the word to indicate merely the absence of belief in God. Such a re-definition trivializes the claim of the presumption of atheism, for on this definition atheism ceases to be a view, and even infants count as atheists. One would still require justification in order to know either that God exists or that He does not exist.
Other advocates of the presumption of atheism use the word in the standard way but insist that it is precisely the absence of evidence for theism that justifies their claim that God does not exist. The problem with such a position is captured neatly by the aphorism, beloved of forensic scientists, that "Absence of evidence is not evidence of absence." The absence of evidence is evidence of absence only in cases in which, were the postulated entity to exist, we should expect to have more evidence of its existence than we do. With respect to God's existence, it is incumbent on the atheist to prove that if God existed, He would provide more evidence of His existence than what we have. This is an enormously heavy burden of proof for the atheist to bear, for two reasons: (1) On at least Christian theism the primary way in which we come to know God is not through evidence but through the inner work of His Holy Spirit, which is effectual in bringing persons into relation with God wholly apart from evidence.5 (2) On Christian theism God has provided the stupendous miracles of the creation of the universe from nothing and the resurrection of Jesus from the dead, for which events there is good scientific and historical evidence—not to mention all the other arguments of natural theology.6 In this light, the presumption of atheism seems presumptuous, indeed!
The debate among contemporary philosophers has therefore moved beyond the facile presumption of atheism to a discussion of the so-called "Hiddenness of God" —in effect, a discussion of the probability or expectation that God, if He existed, would leave more evidence of His existence than what we have. Unsatisfied with the evidence we have, some atheists have argued that God, if He existed, would have prevented the world's unbelief by making His existence starkly apparent. But why should God want to do such a thing? On the Christian view it is actually a matter of relative indifference to God whether people believe that He exists or not. For what God is interested in is building a love relationship with us, not just getting us to believe that He exists. There is no reason at all to think that if God were to make His existence more manifest, more people would come into a saving relationship with Him. In fact, we have no way of knowing that in a world of free persons in which God's existence is as obvious as the nose on one's face that more people would come to love Him and know His salvation than in the actual world. But then the claim that if God existed, He would make His existence more evident than it is has little or no warrant, thereby undermining the claim that the absence of such evidence is itself positive evidence that God does not exist. Worse, if God is endowed with middle knowledge, so that He knows how any free person would act under any circumstances in which God might place him, then God can have so providentially ordered the actual world as to provide just those evidences and gifts of the Holy Spirit which He knew would be adequate for bringing those with an open heart and mind to saving faith. Thus, the evidence is as adequate as needs be.
