Suteetat/Halcro, Popper learned from Tarski about 'the
truth'(aka 'satisfaction approach'). Then he used this
approch to illustrate his 'theory of refutation'. A 'theory' in the sense of 'all swans are white'. Thanks to his stay in Australia he was able to demonstrate at some philosophical meeting in England how easy it is to refute an theory. He repeted the universal quantification:
'All swans are white' and then pulled just one black swan
from his hat (?) which he brought from Australia for the
purpose. The colleaques were astonished but the most of then wanted to check if this swan was not painted black.
