As the actual uneasiness which appetite implies can only be excited by the irritable state of my own body, so neither can the desire of the correspondent gratification subsist in that intense degree which properly constitutes appetite, except when it tends to relieve that very same uneasiness by which it was excited. As in the case of hunger.
