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.

Please join me in applauding the ESA - European Space Agency’s historic efforts with the Rosetta Mission and landing a spacecraft on rotating comet. It may seem like a work of fiction, but it is very real, very impressive, and will help us to further uncover the mysteries surrounding the formation of the solar system. They made a beautiful short film using an imaginary landscape to illustrate today’s historic feat.
The greatest gain from space travel consists in the extension of our knowledge. In a hundred years this newly won knowledge will pay huge and unexpected dividends.
[Science] is corrosive of religious belief, and it's a good thing too.
Science is the attempt to make the chaotic diversity of our sense-experience correspond to a logically uniform system of thought.
Anyone who thinks science is trying to make human life easier or more pleasant is utterly mistaken.
Any important disease whose causality is murky, and for which treatment is ineffectual, tends to be awash in significance.
