TAG is a presuppositional apologetic tactic that stands for
the Transcendental Argument for God. In my last post I defended TAG over
against the classical method and tried to be as brief and as simple as I know
how. I am sure I left a lot to be desired from those who are more adept in
Christian apologetics. I humbly request that the reader keep in mind that my goal
is to reach a broader audience. I want to stimulate and challenge those who are
familiar with this field as well as encourage others to become more familiar with
this field. Sometimes that task exceeds the skills and limitations of this
blogger’s abilities. But I am working on it every week, bit by bit.
One of the most challenging objections to TAG is the fact
that conceptual necessity does not require ontological necessity. Michael
Butler frames the problem for us: “The challenge is, this, to bridge the gap
between having to believe the Christian worldview because it provides the
necessary preconditions of experience and showing that the Christian worldview
is true.” Perhaps I should explain what I mean by “conceptual scheme.” A
conceptual scheme, in this context, is a way or method of organizing our
thoughts and experiences in order to make sense of the world. The underlying
premise is that good conceptual schemes are subject to rational justification.
Therefore, a conceptual scheme that is irrational should be abandoned. While it
is true that Christianity, if viewed as a conceptual scheme, is superior, it
does not follow that it is necessarily true. It only means that Christianity
provides the necessary preconditions for experience. It simply means that
Christianity has succeeded in constructing a way to organize our thoughts and
experiences that is impervious to the objections and challenges of its
competitors. Hence, conceptual necessity says nothing about truthfulness. In
other words, conceptual necessity does not necessarily lead to ontological
necessity.
TAG is a powerful argument because it is constructed upon
man’s ultimate epistemological authority, God’s Word. It is an argument that is
built upon the fact of God and His creation. What many young apologists seek is
something that should be of grave concern to the Church. They seek an approach
that is, for the most part, philosophy through and through. In fact, William
Lane Craig promotes this sort of pursuit. Richard Howe himself did not pursue a
theological education. He is educated in philosophy. For many young apologists,
this is the preferred way. Martin Luther wrote, “What are the universities, as
at present…schools of Greek fashion and heathenish manners, full of dissolute
living, where very little is taught of the Holy Scriptures and of the Christian
faith, and the blind heathen teacher, Aristotle, rules even further than
Christ. Now my advice would be that the books of Aristotle, the ‘Physics,’ the ‘Metaphysics,’
‘Of the Soul,’ and ‘Ethics,’ which have hitherto been considered the best, be
altogether abolished, with all others that profess to treat of nature, though
nothing can be learned from them, either of natural or spiritual things.
Besides, no one has been able to understand his meaning, and much time has been
wasted, and many vexed with much useless labor, study, and expense.” [Luther,
Three Treatises, 4, 92-93, via, McManis see below]
TAG argues for God from the impossibility of the contrary. “A
truly transcendental argument takes any fact of experience which it wishes to
investigate, and tries to determine what the presuppositions of such a fact
must be, in order to make it what it is.” [Van Til, A Survey of Christian
Epistemology, 10] For the Christian, no fact can be what it is, apart from God.
Every fact is what it is because God has made it to be what it is. However for
the unbeliever, it is a remarkably different story. When we turn the guns of
reason on the non-Christian worldview, something very interesting happens. The
non-Christian worldview, in all its different versions, is shown to be
arbitrary, inconsistent with itself, or entirely lacking the preconditions
necessary for the intelligibility of knowledge. {Bahnsen, Van Til’s Apologetic,
513]
