Karl Popper’s Stance on Evolutionary Theory: Between Science and Metaphysics

While popular perception has long held that evolutionary theory represents an absolute scientific fact, a scrutiny of the philosophy of science reveals other dimensions. In the 1970s, one of the most prominent philosophers of science of the twentieth century, Karl Popper, declared his firm conviction that evolutionary theory does not meet the criteria of a testable scientific theory, but is in its essence a metaphysical philosophy.

Darwinism is not a testable scientific theory, but a metaphysical research programme.

Popper did not stop there; he confirmed in his later dialogues, including those published in Scientific American, his continued skepticism regarding the foundations upon which the theory rests, despite the surrounding media momentum. The aforementioned magazine devoted space to these doubts under critical titles such as "Darwinism Doubted," reviewing the views of non-religious scientists who share Popper's lack of conviction in the mechanisms of evolution.

Confessions from Within the Scientific Community

In his final book Evolutionary Epistemology, Popper cited confessions from major scientists that place the theory in a methodological predicament. This includes what was mentioned by the scientist C. H. Waddington, who described evolutionary theory as nothing more than a logical tautology—or in other words, an intellectual collusion that explains a thing by itself without providing independent empirical proof.

This discourse restores consideration to the necessity of differentiating between empirical science based on observation and measurement, and philosophical ideologies that cloak themselves in the mantle of science to pass off specific cosmic visions.
