"Clearly many of our beliefs do have positive epistemic status for us (at any rate most of us think so, most of us accept this premise). As we have seen, positive epistemic status is best thought of as a matter of a belief's being produced by cognitive faculties that are functioning properly in the sort of environment that is appropriate for them. The easiest and most natural way to think of proper functioning, however, is in terms of design: a machine or an organism is working properly when it is working in the way it was designed to work by the being that designed it. But clearly the best candidate for being the being who has designed our cognitive faculties would be God."

"This premise of this argument is only a special case of a much broader premise: there are many natural (non-artifactual) things in the world besides our cognitive faculties such that they function properly or improperly: organs of our bodies and of other organisms, for example. (Tony Kenny's design argument)"

"Objection: perhaps there is indeed this initial tendency to see these things as the product of intelligent design; but there is a powerful defeater in evolutionary theory, which shows us a perfectly natural way in which all of these things might have come about without design.

"Reply: (1) is it in fact plausible to think that human beings, for example, have arisen through the sorts of mechanisms (random genetic mutation and natural selection) in the time that according to contemporary science that has been available? The conference of biologists and mathematicians ("Mathematical Challenges to the NeoDarwinian Interpretation of Evolution", ed. Paul Morehead and Martin Kaplan, Philadelphia, Wistar Institute Press); the piece by Houston Smith. The chief problem: most of the paths one might think of from the condition of not having eyes, for example, to the condition of having them will not work; each mutation along the way has to be adaptive, or appropriately connected with something adaptive. (2) There does not appear to be any decent naturalistic account of the origin of life, or of language."

As Hume also pointed out, however, it is hard to think of a good (noncircular) reason for believing that indeed the future will be relevantly like the past.

Theism, however, provides a reason: God has created us and our noetic capacities and has created the world; he has also created the former in such a way as to be adapted to the latter. It is likely, then, that he has created the world in such a way that in fact the future will indeed resemble the past in the relevant way). (And thus perhaps we do indeed have a priori knowledge of contingent truth: perhaps we know a priori that the future will resemble the past.) (Note here the piece by Aron Edidin: "Language Learning and A Priori Knowledge), APQ October l986 (Vol. 23/ 4); Aron argues that in any case of language learning a priori knowledge is involved.) This argument and the last argument could be thought of as exploiting the fact that according to theism God has created us in such a way as to be at home in the world (Wolterstorff.)
