Principles of Liberalism may be described (at least today) as principles of assessing, and if necessary of modifying or changing, existing institutions, rather than of replacing existing institutions. One can express this also by saying that Liberalism is an evolutionary rather than a revolutionary creed (unless it is confronted by a tyrannical regime).
In Karl Popper’s penultimate Liberal Thesis, he delineates tradition’s role: the means for an institution to evolve as situations change, or – perhaps more sinisterly – as the Establishment’s view of the institution’s purpose changes.the prevention of crime [and] detection and punishment of offenders if crime is committed", as mass immigration changes our national makeup police become increasingly the enforcers of last resort when British culture opposes that of the Establishment’s favoured ethnicities. Thus, we see the English flag described as "racist" and a Christian preacher arrested for saying what has been in the Bible for millenia.
(I’m not criticising rank-and-file police, merely illustrating how Establishment opinion drift causes institution mission drift.)I never left the Democrats, the Democrats left me".
But Popper’s unquestioning acceptance that liberalism’s evolution will be in a socially positive direction contradicts a point made elsewhere in Conjectures and Refutations wherein he takes Hegelians and Marxists to task for assuming the same, through mistaking Kant’s triadic layout of his categories for a statement that syntheses will always be preferable to the conflicts they resolve. That, as institutional mission drift shows, depends on the Establishmentarian agenda regarding the conflicts.
I think Popper would reply that in the open society we can’t afford to make any thinker carry the cross of infallibility.
