"The Horse of Schilda"
The citizens of Schilda ... possessed a horse with whose feats of strength they were highly pleased and against which they had only one objection -- that it consumed such a large quantity of expensive oats. They determined to break it of this bad habit very gently by reducing its ration by a few stalks every day, till they had accustomed it to complete abstinence. For a time things went excellently: the horse was weaned to the point of eating only one stalk a day, and on the succeeding day it was at length to work without any oats at all. On the morning of that day the spiteful animal was found dead; and the citizens of Schilda could not make out what it had died of.
In his concluding lecture at Clark University (1910), Freud allegorizes this tale to make a therapeutic point. That is, he endows it with a special meaning for his own purposes by converting it into a parable.
