The influence (for good or ill) of Plato's work is immeasurable. Western thought, one might say, has been Platonic or anti-Platonic, but hardly ever non-Platonic.
Interpretation
Plato's philosophical ideas have significantly shaped Western thought, either by supporting or opposing his concepts.
This quote by Karl Popper emphasizes the profound and enduring impact of Plato's philosophical contributions on Western intellectual history. Popper suggests that almost all subsequent thought can be seen as either an embrace of Plato's ideas or a reaction against them, indicating that it's nearly impossible to escape his influence in philosophical discussions.
In practice
In a lecture on the history of philosophy, one might say, 'As Karl Popper pointed out, the influence of Plato's work is immeasurable.'
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.

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.
Ours is the only religion that does not depend on a person or persons; it is based upon principles. At the same time there is room for millions of persons. There is ample ground for introducing persons, but each one of them must be an illustration of the principles. We must not forget that. These principles of our religion are all safe, and it should be the life-work of everyone of us to keep then safe, and to keep them free from the accumulating dirt and dust of ages.
Read no history: nothing but biography, for that is life without theory.
An Inuit hunter asked the local missionary priest: If I did not know about God and sin, would I go to hell? No, said the priest, not if you did not know. Then why, asked the Inuit earnestly, did you tell me?
When we are young we do not look into mirrors. It is when we are old, concerned with our name, our legend, what our lives will mean to the future. We become vain with the names we own, our claims to have been the first eyes, the strongest army, the cleverest merchant. It is when he is old that Narcissus wants a graven image of himself.
Nothing is more dreadful than private duels in America. The two adversaries attack each other like wild beasts. Then it is that they might well covet those wonderful properties of the Indians of the prairies - their quick intelligence, their ingenious cunning, their scent of the enemy.
