My philological studies have satisfied me that a gifted person ought to learn English (barring spelling and pronouncing) in thirty hours, French in thirty days, and German in thirty years. It seems manifest, then, that the latter tongue ought to be trimmed down and repaired. If it is to remain as it is, it ought to be gently and reverently set aside among the dead languages, for only the dead have time to learn it.
– Appendix D of A Tramp Abroad, “That Awful German Language”
A dog is “der Hund”; a woman is “die Frau”; a horse is “das Pferd”; now you put that dog in the genitive case, and is he the same dog he was before? No, sir; he is “des Hundes”; put him in the dative case and what is he? Why, he is “dem Hund.” Now you snatch him into the accusative case and how is it with him? Why, he is “den Hunden.” But suppose he happens to be twins and you have to pluralize him- what then? Why, they’ll swat that twin dog around through the 4 cases until he’ll think he’s an entire international dog-show all in is own person. I don’t like dogs, but I wouldn’t treat a dog like that- I wouldn’t even treat a borrowed dog that way. Well, it’s just the same with a cat. They start her in at the nominative singular in good health and fair to look upon, and they sweat her through all the 4 cases and the 16 the’s and when she limps out through the accusative plural you wouldn’t recognize her for the same being. Yes, sir, once the German language gets hold of a cat, it’s goodbye cat. That’s about the amount of it.
So I just watched a documentary about octopus species and how it evolved to be very intelligent. It can learn very fast, even observing other octopuses.
In one experiment they put one octopus just beside another but in separate tanks, and one teached another just by showing it once how to open a box from a certain side. Second octopus then got the box and reapeted the same thing.
Box could have been opened from different sides, by different methods, but both octopuses used the same opening method from the same side, the first used more time before however to learn how to open it on its own, second did not lose time for that.
