Continuing a discussion of J. P. Moreland’s introduction to the book The Creation Hypothesis, I now turn to scientism, the belief that science is the only paradigm by which we can obtain truth and rationality. Everything outside of science is merely belief and subjective opinion. The only truth we may know is known through scientific methodology. Although many have not thought through the ramifications of such a belief, many are quick to give it credence.
Moreland distinguishes between two forms of scientism: Strong scientism and weak scientism. Strong scientism holds that their are no truths apart from scientific truths, and even if there are, we have no good reasons to believe them. On the other hand, weak scientism allows for the existence of some truths apart from science, however, all other intellectual activity is subjugated to science, a far more superior and valuable source of knowledge. According to Moreland:
If strong scientism is true, then theology is not a cognitive enterprise at all and there is no such thing as theological knowledge. If weak scientism is true, then the conversation between science and theology will be a monologue, with theology listening to science and waiting for science to give it support . For thinking Christians, either of these alternatives are unacceptable.
Note that strong scientism is a self-refuting belief, i.e., it falsifies itself. Strong scientism is not itself a propostion of science, but a proposition of philosophy about science which states that only scientific propostions are true or rational. Strong scientism is itself proposed as a true, rationally justified position to believe. On what basis? Scientific analysis? No. A self-refuting proposition is necessarily false - it is not possible for it to be true.
Two other problems exist for both weak and strong scientism. First, neither allows for the stating and defending of the necessary propositions which for science to be carried out (e.g., assuming scientific realism, the orderly nature of the external world). The practice of science presupposes several very important philosophical beliefs, without which it cannot work. Moreland states:
The conclusions of science cannot be more certain than the presuppostions it rests on.
John Kekes has stated:
A successful argument for science being the paradigm of rationality must be based on the demonstration that the presuppositions of science are preferable to other propositions. That demonstration requires showing that science, relying on these presuppostions, is better at solving some problems and achieving some ideals than its competitors. But showing that cannot be the task of science. Is is, in fact, one task of philosophy…Hence, philosophy, and not science, is a stronger candidate for being the very paradigm of rationality.
The second problem for both forms of scientism, according to Moreland, is the simple fact that true, rationally justified beliefs exist in many other fields outside of science. For example, “Red is a color” and “I am now thinking about science” are better justified statements than some believed withing science, such as “Evolution takes place throught a series of very small steps”.
Now, I am not bashing science. As a physician I have a strong science background and consider myself to be a scientist of sorts (clinical). The point is that there are domains of knowledge outside of science, including theology and philosophy. As Moreland states, an integrated worldview will consider all three domains. Theistic science attempts to do just that. Next, a look at natural theology.
