Science And Wisdom Part V

Worldviews, The Scientific Method, and Logic

"For the children of the Calvinistic Reformation, there should be no question of wasting time in long scholastic discussions about whether science and philosophy also pertain to the kingdom of Jesus Christ or whether they belong instead to a domain of natural reason. This discussion need not go on, because, as we have shown, there is no natural reason that is independent of the religious driving force which controls the heart of human existence."  (Herman Dooyeweerd - THE SECULARIZATION OF SCIENCE)

Is science neutral when it comes to metaphysics?  If not, then what kind of worldview does science require?

It is no accident that modern science has it's origins in Western culture.  This is not to say that other cultures, both past and present, have never dabbled in science.  Indeed, they have done so in limited fashion despite the fact that their worldviews not conducive to science.  In Eastern philosophies, the physical universe is considered to be "maya", or illusion, and the ultimate goal in these belief systems is to escape that illusion through enlightenment.  Thus any serious study of nature is bound to be limited as a result.  Pagan cultures tend to deify nature.  Therefore, any natural phenomenon can be simply written off as a non-transcendental act performed by an independent spirit, separate from other independent spirits.  Thus there are no real "laws of nature" to be studied, only spirits to be appeased.

Despite the modern efforts to push science into secularism, there are several major obstacles to science when is approached from a strict materialist point of view, many of which we have already encountered.  It is the Christian worldview that provides the necessary preconditions that make scientific enterprise possible.  Among the most foundational of these preconditions are the doctrines of Creation (justification that the physical universe is real) and Providence (justification for the uniformity of nature and inductive reasoning).  These presuppositions can be more readily seen as we examine the scientific method itself.

Here is a rundown, more or less, of what is referred to as the scientific method. 

1.)  Define the question.
2.)  Gather information and resources.
3.)  Form hypothesis.
4.)  Perform experiment and collect data.
5.)  Analyze data.
6.)  Interpret data and draw conclusions that serve as a starting point for new hypothesis.
7.)  Publish results
8.)  Retest (frequently done by other scientists)

Before one can even begin the scientific method as an approach to examining truth claims, certain metaphysical assumptions must be made that a non-believer has no right to make.  The very first step, defining the question, requires a certain bias from the very outset, already precluding certain possibilities.  Other metaphysical requirements necessary to engage in any science discipline are as follows:

The Christian Metaphysical Requirements For Science
Existence Isaiah 40:26
Reality Acts 17:28
Knowledge Colossians 2:3
Order Jeremiah 33:25, 51:15
Uniformity Hebrews 1:3

In addition to the metaphysical obstacles to strict materialism, the attempts to establish the scientific method as an authoritative truth in and of itself presents another problem.  The fact is that the scientific method cannot possibly tell us anything true about a hypothesis.  Rather, it is built upon the logical fallacy of Asserting The Consequence; ("If P then Q, Q therefore P" is not a valid logical argument), ie.

P1: If Jean Dixon is psychic, then she can predict the winner of a presidential election.
P2: She predicted the winner of a presidential election.
Conclusion: Therefore, Jean Dixon is psychic.

P1: If President Obama was born in Hawaii, then he is an American citizen.
P2: He is an American citizen.
Conclusion: Therefore, President Obama was born in Hawaii.

P1: If Rover is a man, then he is mortal.
P2: Rover is mortal.
Conclusion: Therefore, Rover is a man.

P1: If the law of gravity is true, then the ball will fall to earth at 9.8 m/s2
P2: The ball falls.
Conclusion: Therefore, the law of gravity is true.

P1: If humans and chimps have a common ancestor, then we should observe retroviruses at common points in their DNA structure.
P2: Humans and chimps have similar DNA structure.
Conclusion: Therefore, humans and chimps have a common ancestor.

None of the above arguments are logically sound, yet scientific method itself (hypothesis, experiment, drawing conclusions) is based upon this fallacy.  Even if all of the other metaphysical issues surrounding science were to be either answered or ignored, materialists are faced with this discomforting fact:  A scientific hypothesis can never be proven to be true. The best case one can hope for is that the scientific method can show that any given hypothesis is a valid possibility.

Finally, when we remove the Christian foundation for Science, not only do we make the scientific method irrational, but we rob Science of any real explanatory value.  Science, in a purely secular world, cannot provide a valid explanation for the simplest things, but can only provide:

1.)     Definitions – mere tautologies with no explanatory value
2.)     Matters of observation – with no reason to believe that these observations have any relationship to reality, much less any justification for the universal and unchangeable “lawlike” character of laws.

Only in a Christian Worldview can we justify the leap from Empiricism to Induction, and rationally exclude anomalies.  Only in a Christian worldview can we justify having science operate within the “normal science” paradigm.  Only in a Christian Worldview can we justify universal, invariant laws.  Without God’s Providence and unchangeable character, we have no way to define what “normal science” should be.  Science, far from being a Tarshish for modern Jonah’s to flee to, is a discipline firmly established in the Kingdom of God, and cannot make any sense of our world apart from God.  Therefore, we can once again prove God’s existence by the following declaration:

P1: If the laws of nature exists, then God exists, since God is the precondition of the laws of nature.

P2: The laws of nature exists.

Conclusion: God exists.

Unbelieving scientists live in God's universe, and like anyone else, must acknowledge Him in order to even function, though they may suppress the truth in unrighteousness.

Little wonky there. Look into "Solomonoff Induction". A solid formal account of the scientific method from Algorithmic Information Theory.
