This blog post explores whether it is truly justified to interpret areas science has yet to explain as the intervention of an ‘intelligent being’. Through the clash between evolution and intelligent design theory, we deeply examine where the boundary lies between scientific evidence and theological interpretation.
In a world dominated by creationism—the belief that God created the universe and life—Darwin emerged and proposed ‘evolutionary theory’. This theory fundamentally challenged creationism, which asserted humans were created by God. Simultaneously, science advanced rapidly, beginning to explain natural phenomena—previously attributed only to divine providence or demonic mischief—through scientific logic. Consequently, religion, which had dominated humanity’s worldview, faced a severe crisis. Science’s clear logic and solid evidence stripped away many of the veneers religion had maintained through mere assertions. Some ardent believers in science even go so far as to say that once science resolves all of nature’s mysteries, religion will become a system no longer needed. Amidst this total crisis for religion, a new savior emerged: ‘Intelligent Design’.
According to ‘Intelligent Design Theory’, the objects of natural inquiry are defined not as ‘products of chance’ but as ‘intentionally created’. The probability of life, such as humans, emerging on Earth since the beginning of the universe is extremely minuscule. The argument is that each step in that progression has a probability so low it borders on a miracle, making it difficult to explain the emergence of life without some form of external, artificial manipulation. Proponents of ‘Intelligent Design Theory’ criticize the scientific community for blocking any religious elements from entering its domain, arguing that questions still unexplained by science can be resolved using theological elements. They further contend that such theological elements can function as scientific grounds, presenting various logics that appear scientifically plausible.
The first argument they present is ‘irreducible complexity’. This refers to the characteristic of a system, where multiple parts combine to perform a function, such that if any single part is removed, the entire system ceases to function. As illustrated in the book’s example of a mousetrap, it operates on the principle that if even one spring is missing, the entire device fails. Intelligent design advocates use this ‘irreducible complexity’ as one of their primary arguments against evolutionary theory. According to evolutionary theory, each mechanism enabling the existence of current life forms evolved over long periods of time, and its components would have been incomplete in the early stages. Therefore, the view that their functions were also incomplete holds. Following this logic, it follows that the entire system could not have existed in a complete form in its early stages.
The second argument is the ‘fine-tuned universe’. As explained earlier, countless conditions must be met for life to emerge in the universe, and the probability of all these conditions aligning is so low it borders on miraculous. The argument is that even a slight deviation in these conditions would have prevented life from emerging. Therefore, it is difficult to view this as having happened by chance; the logic is that intentional adjustment by an ‘intelligent being’ must have intervened. This argument also appears to hold considerable persuasive power.
The next argument presented is ‘explanatory complexity’. This argument is based on the premise that a system that is both complex and well-ordered is unlikely to arise from random chance. The process of randomness and chance, upon which evolutionary theory is founded, is deemed insufficient to produce such ‘complex and well-ordered’ life forms. Advocates of intelligent design argue that this too can ultimately only be explained by the intervention of an ‘intelligent being’. While various other arguments, such as the ‘watchmaker argument,’ are presented, they ultimately converge on the claim that only the intentional intervention of an ‘intelligent being’ makes the existence of life possible.
‘Intelligent design theory’ presents these various grounds and challenges ‘evolutionary theory’ through philosophical questions about life. In response, evolutionary theory attempts to refute these arguments by presenting evidence based on scientific logic and an empirical approach. Of course, it is clear that ‘evolutionary theory’ itself has inherent limitations. It is within this context that ‘intelligent design’ emerges, exploiting these gaps. Evolutionary theory has accumulated vast evidence over decades to reach its current solid academic standing, yet its essence remains a hypothesis established based on observations of nature. Even with continuous verification, the very perspective through which nature is viewed remains confined within the framework of that hypothesis, resulting in the acceptance of only limited information. Above all, because evolution is a theory, its errors can be proven if counterexamples are presented. In other words, evolution remains merely a ‘theory close to the truth,’ while simultaneously retaining the possibility of being wrong. Therefore, research to date can be seen as an ongoing effort to elevate evolution—still just a hypothesis—to the level of a complete law.
To refute any theory, one must present cases that contradict its underlying logic. This requires meticulously seeking out such cases and carefully analyzing whether they genuinely conflict with the theory. Similarly, to refute ‘evolutionary theory,’ one must present cases that substantially contradict it. However, ‘Intelligent Design Theory’ fails to present direct evidence contradicting evolution. Instead, it relies on areas not yet explained by evolution or other scientific fields. They claim evolution is wrong solely because it cannot explain certain phenomena, asserting that the origin of life is possible only through intelligent design. Yet, they fail to present any actual evidence, merely repeating the assertion that only an ‘intelligent being’ can provide the answer. A mere assertion cannot constitute science. Only a clear logic, subjected to numerous challenges for verification, and a system refined through such challenges, can be considered a scientific approach. An attitude that merely gathers evidence for the sake of refutation, without undergoing this process, deserves criticism.
Empirical science excels at explaining the various phenomena and processes of the surrounding world. Yet it is also true that it cannot explain the fundamental causes behind those processes. This connects to an agnostic perspective. It may be fundamentally impossible for human cognition to fully grasp the essence of things. Ultimately, science is a discipline constructed within the limits of human cognition, inherently constrained in revealing the essence of things. For this reason, it is natural that science cannot exert its power in discussions about the origins of existence at present. However, this does not justify a logic entirely distinct from science declaring its own correctness based solely on unfounded assertions. Such an attitude is clearly wrong; it is merely an empty cry, neither scholarship nor theory. Ultimately, all citizens of the Republic of Korea must guard against such attitudes and uphold a healthy forum for discussion where scientific inquiry and philosophical thought achieve balance.
