In an apologetic
debate, the situation is not that both unbeliever and
believer have shared epistemological standards, and that we
are just to argue from supposed brute facts to a "best" or
"probable" conclusion concerning the existence of God. But,
sadly, this is the typical approach used by Christian
evidentialists in their approach to apologetics. In so
arguing, they have adopted the unbeliever's non-self-verifying standards and have adopted an antitheistic
presupposition. They have reduced themselves to the
skeptical position of the unbeliever in which there is no
certain knowledge of anything.
To be sure, there is a purely formal agreement between
belief and unbelief regarding deduction, induction, and the
scientific method -- but the similarity ends there. The
disagreement is over the nature, source, and authority of
these.
The unbeliever has no justification for his
principles of deduction or induction or why the scientific
method works. They are all merely
assumed in
his worldview. They are also epistemological
presuppositions that do not comport with his espoused
metaphysics (e.g., how immaterial, abstract, unchanging laws of
thought arise out of ever-changing material in flux.). The
unbeliever can provide no
reason for reason.
For instance, the unbeliever must assume the future will be
like the past (uniformity of nature) in order for induction
to proceed, but he has no proof of such. It is not a
necessary truth, it cannot be deduced or demonstrated.
Induction itself cannot be invoked to support induction.
It is a circular argument.
Past and
present evidence provides no basis for
extrapolation to the
future. The only appeal is "so far, so
good." It is a
faith
commitment. Hume's skeptical argument regarding induction
remains unanswered. Further, the unbeliever cannot even
assign a probability to the uniformity of nature. That
would require him to know everything -- to have been
everywhere for all time -- to be God.
The same problem exists with causation. Causation (continued
necessary conjunction of causes and effects) itself assumes
the uniformity of nature. This is a
faith
commitment. Unbelievers of a superficial scientific bent
(which is the majority of unbelievers in this modern age of
technology) have repeatedly said things of the sort:
nature
appears to be orderly, let's assume it's so.
Let's not. As Christians we do not. To assume this
in
vacuo is to assume the atheist presupposition that the
material universe is the totality of reality --
self-existent with eternal inherent properties. This is the
atheist's circular (and self-contradictory) faith
commitment. The morally culpable unbeliever worships the
creation rather than the Creator (Romans 1:25). But, the
universe is not the totality of reality, it is not
self-existent, and the idea of eternal physical matter is
self-contradictory.
According to modern physics, the world is not quite as
orderly as the scientifically naive say. The modern view of
naturalistic science is that reality is a combination of
both law (supposed invariant properties of matter) and
lawlessness (irreducible and unknowable chance, i.e.,
metaphysical irrationalism). On this basis, the claim that
nature is uniform is completely undermined since what occurs
is, in fact, given by ultimate lawlessness (lack of
causality) filtered through inexplicable law-like patterns
(properties of matter). Some even assert that the laws
themselves are also "flukes" and not necessarily invariant
(e.g., John A. Wheeler's remark: "The only law is the law
that there is no law," quoted in James Gleick,
Genius:
the Life and Science of Richard Feynman (1993),
p.93). The unbeliever doesn't even know if additional
undiscovered forces are "lurking in the unknown mysterious
universe," only to be triggered by some catastrophic
uncaused random
event. In any case, the unbeliever, in the face of such,
is devoid of knowledge. He cannot even claim he has a
mind engaged in volitional reasoning. Whatever physical
processes are occurring in his physical brain are also
lawless random events filtered through a maze of patterns.
His brain is nothing more than a quantum mechanical
pachinko machine, in which every "thought" is nothing more than random
effects -- the clatter of random motions of pachinko balls.
There is nothing in those random processes that can be
called a "mind" or the free exercise of "reason." There is
nothing in his brain that corresponds to a
self that
is making arguments and logical choices. Yet, in the face
of such analysis, the unbeliever asserts his freedom (autonomy) and personality, and holds that rationality is
accounted for by the (nonexistent) mind of man -- not the
mind of God. The unbeliever then presumes to argue against
Christ by way of his (nonexistent in his worldview)
"autonomous reason." An incredible example was
Christopher Hitchens: "Nonetheless, here I am reasoning."
[Hitchens-Wilson interview Imus in the Morning.] It is in
the light of such evidence (atheists actually arguing
against Christianity) that Bahnsen remarks that "if
naturalism is true, the naturalist has no reason to believe
it" and that the atheist has already lost the debate by
showing up at the debate. That is: The unbeliever's
worldview is self-contradictory and his actions do not
comport with his metaphysical presuppositions.
So then, the unbeliever cannot account for and neither does he
know these
things (induction, uniformity of nature), and since he has
no knowledge of them, anything derived from them is not
knowledge.
Therefore, with no knowledge, there is no certain foundation
from which he can conduct a case to judge
any
fact or prove
anything. In short, nothing
in the unbeliever's worldview yields certain knowledge of
the external world. And with that goes the claim of
scientism: "only science yields knowledge." A claim that,
we have mentioned before, is itself not a scientific truth,
since it is neither deducible nor empirically observed. Thus, not being science, the claim declares itself to be not known.
The Christian does have justification for each of the above
(deduction, induction, the uniformity of nature) in the
absolute transcendent God, the eternal Sovereign Creator of the
cosmos.
God has created man in His image with volition and a mind
that has the capacity to think rationally according to the
abstract laws of thought ("logic"). These laws of logic as
constituted in man are a reflection of God's thoughts.
The law of induction works because God is the author of
physical causation and the uniformity of nature, and
according to his unchanging character, He maintains the
creation; the laws he has created will be the same tomorrow
as they are today and were yesterday. Only on the
presupposition of the absolute personal God revealed in the
Bible can a scientist make the claim to knowledge. Only on
the basis of Christianity is there knowledge, and that
knowledge is rooted in the certain knowledge of God.
For by him were all things created, that are in heaven, and
that are in earth, visible and invisible, whether they be
thrones, or dominions, or principalities, or powers: all
things were created by him, and for him: And he is
before all things, and by him all things consist.
(Colossians 1:16-17)
God... hath in these last days spoken unto us by his Son,
whom he hath appointed heir of all things, by whom also he
made the worlds; Who being the brightness of his glory, and
the express image of his person, and upholding all
things by the word of his power, when he had by
himself purged our sins, sat down on the right hand of the
Majesty on high; (Hebrews 1:1-3)
In the beginning was the Word, and the Word was with God,
and the Word was God. 2 The same was in the beginning with
God. 3 All things were made by him; and without him was
not any thing made that was made. (John 1:1-3)
So then, the unbeliever, in sinful rebellion, takes himself as the final authority
and presumes to explain reality by means of his own
merely assumed and inexplicable non-self-verifying
principles. He rejects God's revelation surrounding him
and within him by his assumed incoherent philosophy of
necessity, chance, and his own autonomy. As his own final
authority, he asserts his freedom and personality. He presumes to interpret himself, his existence
(as uncreated by God), and the facts of a godless and impersonal random
universe (of which he, too, is just a random fact). He falsely takes himself as an innocent truth seeker and in no need of a Redeemer.
Christians believe none of that. Our final authority is the
self-attesting and self-authorizing absolute God who is the Creator
of man and the cosmos; it is in terms of God's revelation in
the Bible and in nature that we interpret ourselves and the
cosmos. From that we have the assured basis of true knowledge, human
reason, deduction, induction, and the scientific method. The fear of the Lord is the beginning of knowledge.
