For example: you put a hungry animal, say a cat, in a cage which has a door that can be opened by lifting a latch; outside the cage you put food.
The objection to this view, if taken as the sole explanation, is that on improvement ought to set in till after the SECOND trial, whereas experiment shows that already at the second attempt the animal does better than the first time.
The Law of Effect is that: Of several responses made to the same situation, those which are accompanied or closely followed by satisfaction to the animal will, other things being equal, be more firmly connected with the situation, so that, when it recurs, they will be more likely to recur; those which are accompanied or closely followed by discomfort to the animal will, other things being equal, have their connections with that situation weakened, so that, when it recurs, they will be less likely to occur.
The bullet did its work; it hit the animal, and, sliding off the rounded surface, was lost in two miles depth of sea.
Now I thought our expedition was at an end, and that we should never again see the extraordinary animal.
The frigate approached noiselessly, stopped at two cables' lengths from the animal, and following its track.
That large animals require a luxuriant vegetation, has been a general assumption which has passed from one work to another; but I do not hesitate to say that it is completely false, and that it has vitiated the reasoning of geologists on some points of great interest in the ancient history of the world.
Now, if we look to the animals inhabiting these wide plains, we shall find their numbers extraordinarily great, and their bulk immense.
Those tertiary epochs, which we are apt to consider as abounding to an astonishing degree with large animals, because we find the remains of many ages accumulated at certain spots, could hardly boast of more large quadrupeds than Southern Africa does at present.
I may add, that as some organisms will breed most freely under the most unnatural conditions (for instance, the rabbit and ferret kept in hutches), showing that their reproductive system has not been thus affected; so will some animals and plants withstand domestication or cultivation, and vary very slightly--perhaps hardly more than in a state of nature.
is most difficult: my impression is, that with animals such agencies have produced very little direct effect, though apparently more in the case of plants.
When we look to the hereditary varieties or races of our domestic animals and plants, and compare them with species closely allied together, we generally perceive in each domestic race, as already remarked, less uniformity of character than in true species.
Ah, mine animals, this only have I learned hitherto, that for man his baddest is necessary for his best,--
Then did his animals prevent him from speaking further.
so answered his animals, "but go out where the world waiteth for thee like a garden.
