And one form of desire is thirst and hunger: and here arises a

new point-thirst is thirst of drink, hunger is hunger of food;

not of warm drink or of a particular kind of food, with the

single exception of course that the very fact of our desiring

anything implies that it is good. When relative terms have no

attributes, their correlatives have no attributes; when they have

attributes, their correlatives also have them. For example, the

term 'greater' is simply relative to 'less,' and knowledge refers

to a subject of knowledge. But on the other hand, a particular

knowledge is of a particular subject. Again, every science has a

distinct character, which is defined by an object; medicine, for

example, is the science of health, although not to be confounded

with health. Having cleared our ideas thus far, let us return to

the original instance of thirst, which has a definite

object-drink.
