What seems absurd depends on one's prejudice.
The case for the scientific method should itself be "scientific" and not merely rhetorical.
Unfortunately, the argument may not look as good to the unconvinced as it does to the believer.
Vod apparently does not realize that the repeated promises of benefits yet to come, with no likelihood that those promises will be fulfilled, can only produce a widespread cynicism about the claims for the scientific method.
Our willingness to accept scientific claims that are against common sense is the key to an understanding of the real struggle between science and the supernatural. We take the side of science in spite of the patent absurdity of some of its constructs, in spite of its failure to fulfill many of its extravagant promises of health and life, in spite of the tolerance of the scientific community for
unsubstantiated just-so stories, because we have a prior commitment, a commitment to materialism. It is not that the methods and institutions of science somehow compel us to accept a material explanation of the phenomenal world, but, on the contrary, that we are forced by our a priori adherence to material causes to create an
apparatus of investigation and a set of concepts that produce material explanations, no matter how counter-intuitive, no matter how mystifying to the uninitiated. Moreover, that materialism is absolute, for we cannot allow a Divine Foot in the door. The eminent Kant scholar Lewis Beck used to say that anyone who could believe in God could believe in anything. To appeal to an omnipotent deity is to allow that at any moment the regularities of nature may be ruptured, that miracles may happen.
Ultimately,
It is not the truth that makes you free. It is your possession of the power to discover the truth.
