It's like saying that if a cat needs to pee and can solve that problem, then that cat is a very intelligent creature. If that's what you mean by Senzaki's intelligence - well, I'm sure he can do more than that, but that's a basic instinct. And I don't know about scale, but there are intelligence tests that people have to do to prove themselfs. Those psychologists who gave that definition of intelligence didn't mean it for 3year olds, that's why they didn't have to use thousand words to explain that by problem solving they didn't mean using a bathroom or washing hands (or so I think). By giving examples of that kind of "problem solving" you will come to a conclusion that every living creature is a genious, but that's definitly not the case. And no, I disagree that Karino demonstrates high intelligence particulaly in that moment.
"very" and "high" are your addition. I am simply talking about "intelligence" as opposed to "totally stupid". But yes, the psychologists who define intelligence do mean it for 3-year-olds. If they are trying to measure "IQ" they usually test for performance on standardized tasks involving those skills and account for age of the child in the way IQ is calculated. But we aren't talking about measuring intelligence, merely saying it exists rather than a character or action being completely stupid of devoid of all thought.
Again, I think you are refusing to see how the actions fit the definition because you do not value the type of actions or skill set involved. What Senzaki did was more than use a bathroom (washing hands is intelligent BTW, though it can also be a learned behavior). Even if we ignore the problem solving, Senzaki is demonstrating he is thinking about complex abstract concepts when he discusses his transcendent love. But everything he does is more than habit or simple biological function.
A cat defecating is instinct (or a biological process--burying it is instinct). But if you do not clean the litter box or let them out, it will become creative and start problem-solving. You won't like it, but the cat will assess the situation and make adjustments. It's isn't jus that the cat will go anywhere (unless it is sick). The cat will plan where else it can go, and will either try to hide it or put it someplace you will find it on purpose--say your slippers (because you should clean the damned litter box). This indicates the cat is reasoning.
But a better analogy is the way cats hunt and teach kittens to hunt. If you watch closely, cats are very intelligent in how the plan and apply their skills while hunting. If you doubt this is planned behavior, observe a mother cat bringing a half dead mouse back to kittens. She does this to teach them. It is planned. It involves reasoning and learning. Cats demonstrate "intelligence".
If for you intelligence is washing hands and using a bathroom, as I said, I'm sure he can do more than that, I dare say he can even take a shower. But that's not what we were talking about and I never said that he was completely stupid, but that he has yet to show his intelligent side. But if by Senzaki's intelligence you mean an "inelligence" of a cat (or a chicken for that matter) - it's fine by me, but that's definitely not what I meant by being smart and intelligent.
PS Ever heard of "Brevity is the soul of wit"?
Good. Now do you know what people mean by saying that? It means "keep it short".
