       | planets and gravitational attraction (which are fairly advanced
       | concepts) while at the same time being completely unaware that
       | animals can migrate long distances.
       | 
       | You'd think migration is a very easily-explainable phenomenon.
       | But for thousands of years it completely flummoxed Western
       | thinkers. The big breakthrough came in 1822, when a stork arrived
       | in Germany... carrying an African-made arrow impaled through its
       | neck.

         | recentish phenomenon.

       | I would suspect, had one guessed in 1685 that the birds arriving
       | that Halloween in London had been relaxing in Spring around the
       | Caspian Sea, you would have been laughed at. Persia in the 1600s
       | might as well have been the moon. I suppose one can forgive them
       | for their lack of belief in the power of our fellow animals -
       | that is more or less the major mistake of their time period:
       | hubris.

       | much, if it come from any remote part of the earth, it first
       | mounts above the attraction of the earthly globe before it begins
       | its journey toward us. Which, if it be gained, it fairly helps
       | our supposal, as is before noted; for if there be such an
       | attraction (which is called gravity) and it have bounds in a
       | certain height, then it may as well serve their going to the moon
       | as to some other parts of the earth.
       | 
       | I do love this though. Perhaps birds travel to the moon! One
       | cannot fault him for lack of imagination.

         | <pedantic engineer voice>The distance to the moon was well-
         | enough known at the time, though. That's quite a migration! And
         | I think they should at least be entertaining a strong doubt
         | about air along the way: from how attenuated the sun/moon look
         | near the horizon vs. high in the sky, most of whatever's
         | attenuating that light stays very near the Earth. I think
         | astronomers had been accounting for refraction from the
         | atmosphere since at least Tycho Brahe.
         | 
         | Added: just found this on the early history of atmospheric
         | refraction.

           | Indeed but the bit about "maybe gravity stops applying at
           | some point" is key. Just floating to the moon seems more
           | doable that that this small huntable bird has an active
           | domain larger than any human empire ever.
           | 
           | Like obviously they were way wrong - but I think it's
           | important to frame historical ideas with an honest "what
           | would I have to believe in order to believe this".

             | Agreed! I wanted to come across in a "yes, and" spirit. I

             | too. Such as a distance that'd take weeks of travel at the
             | speed of a jet plane -- much faster than a hurricane --
             | nonstop. Some such celestial current is also quite a thing
             | to imagine.

       | His main problem seems to be missing data (specifically about
       | where birds migrate to). I wonder how many things we are wrong
       | about from lack of data that people in the year 2359 will look
       | back at us like we look back at Charles Morton.

       | other men, find that there is any man who has seen them out of

       | I don't know this Charles Morton. But, with all due respect to
       | the guy, I bet his colleagues would have pointed out the weakness
       | of his argument...
       | 
       | Morton must have known about the existence of South America (and
       | the vast tracts of unexplored N. America) as well as Asia and
       | Africa.
       | 
       | Surely he wouldn't have expected to have found treatises on bird
       | populations written by Incas and Zulus, Chinamen and Mongols, in
       | whatever collection of writings he had access to.
       | 
       | I think he may have really wanted to believe in the moon theory.
       | 
       | Perhaps thats the lesson here... not so much missing data, as a
       | blind spot for fallacies when you have a cool thing you want to
       | believe in.
