Världens finaste frisyr

David Deutsch säger bättre vad Antropofagi trevade efter i det här gamla inlägget (samt i någon mån i det här gamla inlägget). Citat:

"We don't expect any of our knowledge to be completely true. Newtons laws were thought to be the last word in mechanics and gravity and dynamics and so on, for hundreds of years. And then they were overturned in quick succession by Einstein’s relativity and by quantum theory. And now we know that they are false. Now they are still knowledge – knowledge doesn’t have to be true, it just has to contain some truth in order to be useful."
