The Philosophy Underlying Secular GeoHistory’s Timescale

Dear hijas,
It’s been a while since I’ve posted, and I still hope you’re reading when you have time. I want to pick up in Chapter 4 of Dr. John K. Reed’s book “Rocks Aren’t Clocks: A Critique of the Geological Timescale.”

What I think we must understand in all this is that we are talking about two opposing worldviews: the Christian worldview versus the secularist worldview (naturalism). God sees men and women in either one of two camps: 1) in Adam, or 2) in Christ. We are either in Adam, unregenerate and dead in our sin and trespass, or under grace in Christ and regenerate to a new life in Him. The Christian worships and serves the Creator, the non-Christian worships and serves herself as the creature (Rom. 1:25). Those are the only two options, and you can’t be half in one and half in the other. It’s an either/or proposition.

When it comes then, to secular geohistory and its billion and millions of year timescale, we must seek to understand from a philosophical viewpoint what the foundations are upon which this timescale was built. If you’ve been reading my posts, you’ll remember that I’ve said that things started to change in this regard in the late 18th century with the Age of Enlightenment. The late 1700’s and early 1800’s are considered to be the start of this new field of geology and the development of its timescale. To our point then, Reed says,

…the timescale possesses a burden of bias stemming from hidden philosophical foundations…stratigraphers use science as a façade to mask philosophical commitments of the naturalistic worldview.

We must remember that naturalism presents itself, to those who can see through its scientific facade, as a religion. As a religion, there are philosophical underpinnings. So, what are the underpinnings or foundations of naturalism’s geologic timescale? Reed says “there at least three ideas closely tied to naturalism that form the foundation of the timescale”:

1) Evolution
2) Uniformitarianism
3) Deep Time

So, let’s take the first one in our list above: evolution. How is evolution an underpinning of the timescale? Reed explains,

The timescale is all about the sequential ordering of a chronology of the past. Arranging any group of objects in a specific order requires a key. This key must contain something in common with all the pieces to be able to unite them into a common group…What is the ‘key’ that allows sequential ordering of different rock layers? It’s not the kind of rock because most rock types are present in most eras. Limestone can be Proterzoic or Paleozoic. Its not the thickness of the formation or the thickness of the beds that make up the formation. In fact, it’s not any physical property. Instead, it is their age–an intangible span of time. What then is the key to assigning discrete time spans to particular formations? Consult any stratigraphic text, and you will see that it is evolution.

It is the changes in fossils, from a progression of simple to complex inherent in evolution, that date strata. “In other words”, Reed says, “the key that allows geologists to assign one layer to one age and another layer to another age is the evolutionary stage of their respective fossil contents…Evolution is the clock by which the rocks are calibrated and arranged in the timescale”.

Reed concludes,

Thus, evolution is crucial to the timescale. How we understand the nature of evolution then affects how we see the timescale… Evolution and the timescale are thus linked by their mutual symbiotic dependence on naturalism. Evolution needs enough time for gradual transformative progress on the biological side, and the timescale is the key to its chronology. That symbiosis is cemented by a mutual antipathy to biblical history. A past without God must explain existence and diversity of life in both present and past. Evolution claims to do so, within the deep time provided by geologic history.

We’ll look at the other foundations in my next post.

With love I remain,
Dear ol’ Dad
