The philosopher Karl Popper nailed it perfectly in his book “The logic of scientific discovery” (“Logik der Forschung”). His central argument: Scientific theories are the result of a creative imagination. The growth of scientific knowledge rests on the doctrine of falsifiability: only those theories that are testable and falsifiable by observation and experiment are properly open to scientific evaluation.
Strictly interpreted, Popper argues that no number of experiments can ever prove a theory, but a single experiment can contradict one. Hence, the more experiments or measurements confirm a theory, the more confident we may become that this theory is valid. Or, with a statistical twist: the more probable it is that this theory holds true, but this probability will never attain 100%. Hence, we should resist the human need for certainty to which scientists are not immune, regrettably.
Mann kann über das Thema denken wie mal will, aber ein Blick in Länder, in denen die de facto Masseneinwanderung aus Nahost und Afrika schon länger stattfindet, kann lehrreich sein. Dazu ein interessanter Artikel im “The Economist” (2013) zur Immigration in Schweden. Auch die Kommentare sind z.T. lesenswert.
You may have you own opinion on this issue, but a look at those countries which experience de facto mass immigration from the Middle East and from Africa for several years already, may teach us something. An informative piece in “The Economist” (2013) on Sweden’s experiences, some comments are interesting, too.
… I was a young student of marine sciences. You see me here 1982 on board of a research vessel fighting its way through the unruly waves of the Baltic. I am fond of the ocean and its creatures, still. Made some progress since those days, not only in terms of my professional career, became even a bit wiser – at least I hope so. And this is what this blog is about, how I see the word and humankind in all its enigmatic beauty.
