Today longstanding shared presuppositions about reality continue to evanesce. We not only think about different things, but we think differently. The scientistic worldview that continues to expand legitimate science beyond its legitimate domain normalizes relativism. This relativism is not arrived at through philosophical reasoning, but rather by viewing life as either only understood or best understood by what science can tell us. Thus, each aspect of life, marriage, morals, child rearing, etc., are merely experiments, and as experiments, they are neither right nor wrong, but rather they either work or do not.
Christian apologist and evangelist Francis Schaeffer (1912-1984) wrote similarly about the importance of this shift, “So this change in the concept of the way we come to knowledge and truth is the most crucial problem, as I understand it, facing Christianity today.”
