Is being wrong not necessarily a part of learning, of becoming right? To learn from your mistakes? Of all people, I would not have expected this from you, Philologos. You should not despise being wrong. To me, you seem like a sort of Socrates of the modern age, reading some of your posts (though some of it may just be the language you use, which I greatly admire for its strangeness and beauty). Being wrong is awful, being right is awful when my friends refuse to admit defeat, but we are mere humans. We are fallible, even you, and to believe that you can not make mistakes is just stupidity no matter how logical you are. Some times I have been constructing a theory, and reached a dead end, trying to look ever deeper, but I then find the answer is on the surface.
Being wrong just tells you that one way does not work, and so you will have one less way to worry about.
And I would not even know the difference between starlings and cowbirds myself, the latter of which I have never heard of before. The fact that you know that one of them lays its eggs in other birds' nests merely shows how great your general knowledge is (unless you are possessed of a desire to study birds).
By the way, you should read the Hitchiker's Guide to the Galaxy, it is brilliant.
