Naturalism, as a dominant worldview in science and culture today, asserts that all phenomena—whether physical, biological, or even psychological—must be explained through natural causes. In naturalism, there is no room for supernatural explanations or divine intervention. The naturalistic framework insists that everything must have a material cause, and that all events are the result of processes we can observe, measure, and understand scientifically. This framework has become the default approach in much of modern science, especially in areas like evolutionary biology, cosmology, and anthropology.
However, **naturalism** as a philosophical system is not without significant problems. It carries with it inherent circular reasoning, making it unable to account for the full breadth of human experience or the complexities of the natural world. Moreover, naturalism often relies on a logical misstep known as the **fallacy of composition**, which is the assumption that what is true for a part must be true for the whole. In this chapter, we will explore how naturalism operates, how it falls into circular reasoning, and how the fallacy of composition undermines the naturalistic explanation of life and the universe.
### **The Framework of Naturalism**
At its core, naturalism is the belief that **nature is all that exists** and that everything must be explained by natural laws and processes. This worldview excludes any possibility of the supernatural, including God, miracles, or divine intervention. As such, naturalism often leads to conclusions that are inherently **closed off to metaphysical explanations**, even when those explanations might be the most plausible.
In naturalism, questions about the origin of the universe, the development of life, and the nature of human consciousness are all assumed to have purely materialistic answers. For example:
- **The origin of the universe** is typically explained through the **Big Bang theory**, which posits that the universe began from a singularity—a point of infinite density—and expanded into the cosmos we see today. Naturalism does not entertain the possibility that a divine Creator initiated this process.
- **The development of life** is explained through **evolutionary theory**, which suggests that life arose from non-living matter through random chemical processes, eventually leading to the complex biological systems we observe today.
- **Human consciousness** is reduced to brain activity, with naturalism claiming that thoughts, emotions, and self-awareness are simply byproducts of chemical reactions and neural processes.
While naturalism claims to provide a comprehensive explanation of reality, its **assumptions** are problematic, and the circularity of its reasoning often goes unnoticed.
### **Circular Reasoning in Naturalism**
One of the central flaws in naturalism is that it engages in **circular reasoning**. Circular reasoning occurs when an argument assumes what it is trying to prove, leading to a conclusion that is already presupposed in the premises. Naturalism does this by assuming that only natural causes exist, then using that assumption to conclude that supernatural causes are impossible.
Consider the following example:
- **Premise**: Only natural causes can explain the universe.
- **Observation**: The universe exists.
- **Conclusion**: Therefore, the universe must have a natural cause.
This reasoning is circular because it assumes at the outset that natural causes are the only valid explanations. It **excludes the possibility** of a supernatural cause (such as a Creator) without considering the evidence that might point in that direction. By starting with the assumption that God doesn’t exist, naturalism inevitably concludes that God isn’t necessary, which leads to a **closed system** of reasoning that cannot be challenged by external evidence.
This circularity is evident in many aspects of naturalistic science, particularly when it comes to questions of origins. For example, when scientists are confronted with the fine-tuning of the universe—the fact that the universe’s physical constants are precisely calibrated to allow for life—naturalism must either attribute this fine-tuning to random chance or propose speculative theories like the multiverse (which posits the existence of countless other universes that we cannot observe). The idea of a Creator who designed the universe is dismissed, not based on evidence, but because naturalism excludes the possibility of supernatural design from the outset.
This circular reasoning undermines the integrity of naturalism as a worldview. It limits inquiry by preventing scientists from considering all possible explanations, including the metaphysical.
### **The Fallacy of Composition**
Naturalism also falls into the **fallacy of composition**, which is the logical error of assuming that what is true for a part must be true for the whole. In other words, just because a particular aspect of life or the universe can be explained by natural causes, naturalism assumes that **everything** must be explained by natural causes.
For example, within **evolutionary biology**, naturalism asserts that because we can observe small changes within species (known as **microevolution**), larger changes (known as **macroevolution**) must also be the result of purely natural processes. However, this is a **fallacy of composition**. While microevolution involves observable adaptations within a species (such as variations in beak size among finches), this does not necessarily mean that these small changes can account for the emergence of entirely new species, or for the development of complex biological systems like the human brain or the eye.
The fallacy of composition is also evident in **cosmology**, where naturalistic scientists often argue that because we can observe natural processes at work in the present (such as the expansion of the universe), the entire history of the universe must be explainable by natural processes alone. This ignores the possibility that supernatural intervention could have played a role in the universe’s origins, as described in Genesis 1:1 (ESV): *"In the beginning, God created the heavens and the earth."* By dismissing this possibility, naturalism again relies on the fallacy that what we observe today can be extrapolated to explain the entirety of cosmic history.
### **How Theoreddism Counters Naturalism**
Theoreddism offers a robust counter to naturalism by acknowledging both natural and supernatural causes. It does not dismiss observable science, but it also recognizes that historical science—when dealing with unobservable events in the distant past—cannot be fully explained by natural processes alone. By adhering to the **hierarchy of truth** established in Theoreddism, we can engage with scientific observations without falling into the errors of naturalism.
For instance:
- **Microevolution** is a well-established fact, but Theoreddism challenges the assumption that macroevolution follows from it. Theoreddism allows for microevolution within the framework of God’s created "kinds," but it denies that these small changes necessarily lead to the development of entirely new species.
- **The fine-tuning of the universe** is recognized as evidence of intentional design, rather than random chance. Theoreddism allows for both natural processes and divine guidance, as demonstrated in passages like Psalm 19:1 (ESV): *"The heavens declare the glory of God, and the sky above proclaims his handiwork."*
By affirming the role of a Creator who actively governs both natural and supernatural events, Theoreddism breaks free from the circular reasoning and fallacies of naturalism, providing a more comprehensive and logically consistent explanation of the universe.
### **Conclusion: Looking Ahead to Random Chance and the Origin of Life**
As we’ve seen in this chapter, naturalism suffers from significant logical flaws, including circular reasoning and the fallacy of composition. These flaws severely limit its ability to provide a coherent explanation of the universe and life itself. The naturalistic worldview is not only incomplete, but it also excludes the possibility of supernatural causes from the start, leading to inadequate conclusions.
In the next chapter, we will explore **The Myth of Random Chance and the Origin of Life**, delving deeper into one of naturalism’s most fundamental claims: that life arose from non-living matter through random chemical processes. We will examine why this explanation fails to account for the complexity and specified information present in even the simplest forms of life, and how Theoreddism offers a more plausible and biblically faithful account of life’s origins.
Stay tuned as we continue to dismantle the assumptions of naturalism and build a solid case for the Christian worldview in the face of a viral culture that challenges faith at every turn.
