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.
Interpretation
Science starts by questioning existing beliefs and myths rather than just collecting data or conducting experiments.
Karl Popper emphasizes that the foundation of scientific inquiry lies in critically examining established myths and beliefs instead of merely gathering observations or inventing experiments. This approach highlights the importance of skepticism and critical discussion in the advancement of scientific knowledge, suggesting that understanding and questioning the underlying assumptions is essential for true scientific progress.
In practice
A speaker at a science conference about the importance of questioning assumptions.
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
I am opposed to looking upon logic as a kind of game. ... One might think that it is a matter of choice or convention which logic one adopts. I disagree with this view.
The image of the scientist who puts the pursuit of truth before anything else has been shattered and replaced by a man on the make or a quasi-religious enthusiast who wants to prove his case at any cost. Science is becoming the tool of campaigning warfare, in which truth is the first casualty.
The methods of theoretical physics should be applicable to all those branches of thought in which the essential features are expressible with numbers.
People who look for the first time through a microscope say, 'Now I see this, and then I see that,' and even a skilled observer can be fooled. On these observations I have spent more time than many will believe, but I have done them with joy, and I have taken no notice of those who have said, 'Why take so much trouble,' and, 'What good is it?'
A strong feeling of adventure is animating those who are working on bacterial viruses, a feeling that they have a small part in the great drive towards a fundamental problem in biology.
Nearly all inventions are not recognised for their positive side either when they're made. So, for example, scientists didn't go out to design a CD machine: they designed a laser. But we got all sorts of things from a laser which we never remotely imagined, and we're still finding things for a laser to do.
There is, however, another subject on which the Queen feels most strongly, and that is this horrible, brutalizing, un-Christian-like vivisection…It must really not be permitted. It is a disgrace to a civilized country.
