Always remember that it is impossible to speak in such a way that you cannot be misunderstood: there will always be some who misunderstand you. - Karl Popper

The difference between Plato’s theory on the one hand, and that of the Old Oligarch and the Thirty on the other, is due to the influence of the Great Generation. Individualism, equalitarianism, faith in reason and love of freedom were new, powerful, and, from the point of view of the enemies of the open society, dangerous sentiments that had to be fought. Plato had himself felt their influence, and, within himself, he had fought them. His answer to the Great Generation was a truly great effort. It was an effort to close the door which had been opened, and to arrest society by casting upon it the spell of an alluring philosophy, unequalled in depth and richness.

And he achieved the somewhat surprising effect of convincing even great humanitarians of the immorality and selfishness of their creed66. I do not doubt that he succeeded in persuading himself. He transfigured his hatred of individual initiative, and his wish to arrest all change, into a love of justice and tempera

...non-reproducible single occurrences are of no significance to science.

Our science is not knowledge (epistēmē): it can newer claim to have attained truth, or even substitute for it, such as probability. . . . We do not know; we can only guess.
