_appetites_; or _physical_ desires or _tastes_, called _desires_
proper. The appetites have their beginning in bodily uneasiness. They
are felt needs of something required for the animal maintenance of the
individual or of the race. The objects of the several appetites are
Meat and Drink, Warmth or Coolness, Exercise and Repose, Sleep, Sex.
The object of mere appetite is marked by quantity only, not by
quality. That is to say, the thing is sought for in the vague, in a
certain amount sufficient to supply the want, but not this or that
variety of the thing. The cry of a hungry man is, "Give me to eat," if
very hungry, "Give me much:" but so far as he is under the mere
dominion of appetite he does not crave any particular article of food,
vegetable or animal: he wants quantity merely. So of thirst, so of all
the appetites, where there is nothing else but appetite present.

2. But if a thirsty man cries for champagne, or a hungry man fancies a
venison pasty, there is another element beyond appetite in that
demand. On the matter of the physical craving there is stamped the
form of a psychical desire. The psychical element prescribes a quality
of the objects sought. The thirsty man thus prompted no longer wants
drink but wine: the man mewed up within doors no longer calls for
exercise, but for a horse or a bicycle. It is obvious that in man the
appetites generally pass into the further shape of psychical desire.
It is when the appetite is vehement, or the man is one who makes
slight study of his animal wants, that pure appetite, sheer physical
craving, is best shown. Darius flying before his conqueror is ready to
drink at any source, muddy or clear, a drink is all that he wants: it
is all that is wanted by St. Paul the first Hermit. But your modern
lounger at the clubs, what variety of liquors are excogitated to
please his palate!
