Whenever a theory appears to you as the only possible one, take this as a sign that you have neither understood the theory nor the problem which it was intended to solve.
Interpretation
The quote emphasizes the importance of understanding multiple perspectives rather than clinging to a single theory.
Karl Popper's quote suggests that if one perceives a theory as the sole explanation for a problem, it indicates a lack of true comprehension of both the theory and the underlying issue. This underscores the significance of intellectual humility and the recognition that complex problems often have multiple valid interpretations and solutions.
In practice
During a lecture on scientific methodologies, refer to this quote to illustrate the need for open-mindedness.
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.

And so, lastly, does the very name of "Catholic", which, not without reason, amid so many heresies, the Church has thus retained; so that, though all heretics wish to be called Catholics, yet when a stranger asks where the Catholic Church meets, no heretic will venture to point to his own chapel or house.
The universe is so immense that it appears immutable, and that the duration of a planet such as that of the earth is only a chapter, less than that, a phrase, less still, only a word of the universe’s history.
It will be necessary for us Indians - Hindus, Muslims, Christians, Jews, Parsis and all others to whom India is their home - to recognize a common flag to live and die for.
One is often told that it is a very wrong thing to attack religion, because religion makes men virtuous. So I am told; I have not noticed it.
The same thing can be both good and bad. Whenever you speak of good, bad is also present. The world is a mixture of both. There is not good without bad. They are both sides of the same coin.
