I have come to the conclusion that Darwinism is not a testable scientific theory, but a metaphysical research programme.
Interpretation
Popper critiques Darwinism as more of a philosophical framework than a strict scientific theory.
In this quote, Karl Popper argues that Darwinism should not be classified as a scientific theory because it lacks the capability to be tested or falsified. Instead, he views it as a metaphysical approach to understanding biological evolution, which suggests that its principles are more about a broader philosophical outlook on life and nature rather than empirical science that adheres to rigorous testing standards.
In practice
This quote can be used in a scientific discussion on the validity of evolutionary theories.
The growth of our knowledge is the result of a process closely resembling what Darwin called 'natural selection'; that is, the natural selection of hypotheses: our knowledge consists, at every moment, of those hypotheses which have shown their (comparative) fitness by surviving so far in their struggle for existence, a competitive struggle which eliminates those hypotheses which are unfit.
If you can't say it simply and clearly, keep quiet, and keep working on it till you can.
No particular theory may ever be regarded as absolutely certain.... No scientific theory is sacrosanct.
The belief in a political Utopia is especially dangerous. This is possibly connected with the fact that the search for a better world, like the investigation of our environment, is (if I am correct) one of the oldest and most important of all the instincts.
A rationalist is simply someone for whom it is more important to learn than to be proved right; someone who is willing to learn from others - not by simply taking over another's opinions, but by gladly allowing others to criticize his ideas and by gladly criticizing the ideas of others
Thus science must begin with myths, and with the criticism of myths; neither with the collection of observations, nor with the invention of experiments, but with the critical discussion of myths, and of magical techniques and practices.
Our criteria is that it's okay to invest in companies so long as they stop lobbying in Washington, stop exploring for new hydrocarbons, and sit down with every one else to plan to keep 80 percent of the reserves in the ground.
Many people find the universe confusing - it's not.
Mathematics, in the development of its ideas, has only to take account of the immanent reality of its concepts and has absolutely no obligation to examine their transient reality.
Some claim evolution is just a theory. As if it were merely an opinion. The theory of evolution, like the theory of gravity, is a scientific fact. Evolution really happened. Accepting our kinship with all life on Earth is not only solid science. In my view, itβs also a soaring spiritual experience.
The further a mathematical theory is developed, the more harmoniously and uniformly does its construction proceed, and unsuspected relations are disclosed between hitherto separated branches of the science.
Every carbon atom in every living thing on the planet was produced in the heart of a dying star.
