“I griped about it at lunch one day to Bill Weist and Dr. Leslie Squier, our visiting psychologists from Reed College. I'd been trying to train one otter to stand on a box, I told them. No problem getting the behavior; as soon as I put the box in the enclosure, the otter rushed over and climbed on top of it. She quickly understood that getting on the box earned her a bite of fish, But. As soon as she got the picture, she began testing the parameters. 'Would you like me lying down on the box? What if I just put three feet on the box? Suppose I hang upside down from the edge of the box? Suppose I stand on it and look under it at the same time? How about if I put my front paws on it and bark?' For twenty minutes she offered me everything imaginable except just getting on the box and standing there. It was infuriating, and strangely exhausting. The otter would eat her fish and then run back to the box and present some new, fantastic variation and look at me expectantly (spitefully, even, I thought) while I struggled once more to decide if what she was doing fit my criteria or not. My psychologist friends flatly refused to believe me; no animal acts like that. If you reinforce a response, you strengthen the chance that the animal will repeat what it was doing when it was reinforced; you don't precipitate some kind of guessing game. So I showed them. We all went down to the otter tank, and I took the other otter and attempted to get it to swim through a small hoop. I put the hoop in the water. The otter swam through it, twice. I reinforced it. Fine. The psychologists nodded. Then the otter did the following, looking up for a reward each time: swam through the hoop and stopped, leaving its tail on the other side. Swam through and caught the hoop with a back foot in passing, and carried it away. Lay in the hoop. Bit the hoop Backed through the hoop. 'See?' I said. 'Otters are natural experimenters.”

“The hemulen woke up slowly and recognised himself and wished he had been someone he didn't know. He felt even tireder than when he went to bed, and here it was -- another day which would go on until evening and then there would be another one and another one which would be the same as all days are when they are lived by a hemulen. He crept under the bedcover and buried his nose in the pillow, then he shifted his stomach to the edge of the bed where the sheets were cool. He took possession of the whole bed with outstretched arms and legs he was waiting for a nice dream that wouldn't come. He curled up and made himself small but it didn't help a bit. He tried being the hemulen that everybody like, he tried being the hemulen that no one liked. But however hard he tried he remained a hemulen doing his best without anything really coming off. In the end he got up and pulled on his trousers. The Hemulen didn't like getting dressed and undressed, it gave him a feeling that the days passed without anything of importance happening. Even so, he spent the whole day arranging, organising and directing things from morning till night! All around him there were people living slipshod and aimless lives, wherever he looked there was something to be put to rights and he worked his fingers to the bone trying to get them to see how they ought to live. It's as though they don't want to live well, the Hemulen thought sadly as he brushed his teeth. He looked at the photograph of himself with his boat which was been taken when the boat was launched. It was a beautiful picture but it made him feel even sadder. I ought to learn how to sail, the Hemulen thought. But I've never got enough time... Moominvalley in November Chapter 5, THE HEMULEN”
