A Proper Epistemology?
It occurs to me that a proper Epistemological foundation begins by acknowledging the premodern notion that all human knowledge is a sub-set of God’s knowledge, while at the same time permitting the postmodern notion that no one has a God’s eye view of reality, truth, society, etc., and that, in effect, we all have relative perspectives (there are many “I’s”). I would rather consider this following modernism through to its logical conclusion, rather than determining it to be a new phenomenon under the heading of postmodernism. The reason being is that I believe we can know truth to a substantial degree. That even if not exhaustively (omnisciently), we can say we hold a true, knowable belief.
In support of this I would turn to Karl Popper’s asymptotic approach, which was developed to explain knowledge acquisition in the field of science. The following diagram was also used by D.A. Carson in his Becoming Conversant with the Emerging Church (pg.119) to explain how we can know a thing without holding omniscient knowledge of a thing:

Carson explains the above diagram as follows. “If the x-axis measures time and the y-axis measure epistemological distance from reality (i.e., how far one’s understanding of something is removed from the reality of the thing itself), then the graph suggests that with time the knower gets closer and closer to the reality, though without ever touching the line that would mark perfect knowledge: we will never be omniscient […] Omniscience is exclusively an attribute of God […] Of course, this curve is rarely smooth. Human understanding can go up and down, in the individual life and in any human culture and in the race at large. But the graph fruitfully portrays that growth in understanding and in knowing something, and in improvement in getting closer to knowledge to what a thing actually is, is possible. (pg. 119–20).
What happens, then, is that even though we view reality subjectively, each from our own perspective, what we’re viewing and interpreting is objective in nature (even if we’re interpreting everything). Our knowledge cannot be said to be omniscient, but despite this, what we know comes so close to the line representing omniscience that we can say we know this thing, and we can say this in confidence.
