Karl Popper (1947, 2011), The Open Society And Its Enemies. Vol I: The Spell of Plato, p. 189

Socrates had refused to compromise his personal integrity. Plato, with all his uncompromising canvas-cleaning, was led along a path on which he compromised his integrity with every step he took. He was forced to combat free thought and the pursuit of truth. He was led to defend lying, political miracles, tabooistic superstition, the suppression of truth, and ultimately, brutal violence. …The lesson which we thus should learn from Plato is the exact opposite of what he tries to teach us. It is a lesson which must not be forgotten. Excellent as Plato's sociological diagnosis was, his own development proves that the therapy he recommended is worse than the evil he tried to combat.

About Karl Popper

Sir Karl Raimund Popper (28 July 1902 – 17 September 1994) was an Austrian-British philosopher, academic and social commentator. One of the 20th century's most influential philosophers of science, Popper is known for his rejection of the classical inductivist views on the scientific method in favour of empirical falsification. According to Popper, a theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can (and should) be scrutinised with decisive experiments. Popper was opposed to the classical justificationist account of knowledge, which he replaced with critical rationalism, namely "the first non-justificational philosophy of criticism in the history of philosophy".
