As Van Til goes on to say, if one does not begin with some such general truths (universals) with which to understand the particular observations in one’s experience, those factual particulars would be unrelated and uninterpretable -i.e., “brute”. In a chance universe, all particular facts would be random, have no classifiable identity, bear no predetermined order or relation and thus be unintelligible to man’s mind.
I recently ran across what I consider a good use case for applying this principle of Christian apologetic’s; On the Reformed Theology G+ forum someone posted the following question: Do you accept the idea of objective morality? If so, what is your criteria for morality that isn’t subjective (open to interpretation)?
Christianity asserts that it is the law of God as revealed in the Bible. This is not a subjective response as it’s an assertion of worldview and is not bound in a single subject or a few peoples opinion. We can also not treat the question of morality as say the shooting average of Lebron James. The rules of interpretation of shooting averages facts do not conflict with opposing worldviews, but of a basic understanding of mathematics.
When we interpret the facts of morality we are dealing with transcendence in that the object is not bound by space or time. For the non-theist that believes everything is essentially ‘matter in motion’ this is antithetical to his presuppositions for which he interprets reality.
So it’s not simply a matter of providing an argument that isn’t open to interpretation, but comes down to how one interprets the facts for which they are observing. And the method of interpretation is driven by their presuppositions.
