-all these you would refer to the classes
already mentioned. You would say--would you not?--that the soul of him
who desires is seeking after the object of his desires; or that he is
drawing to himself the thing which he wishes to possess: or again, when
a person wants anything to be given him, his mind, longing for the
realisation of his desires, intimates his wish to have it by a nod of
assent, as if he had been asked a question?

Very true.

And what would you say of unwillingness and dislike and the absence of
desire; should not these be referred to the opposite class of repulsion
and rejection?

Certainly.

Admitting this to be true of desire generally, let us suppose a
particular class of desires, and out of these we will select hunger and
thirst, as they are termed, which are the most obvious of them?

Let us take that class, he said.

The object of one is food, and of the other drink?

Yes.

And here comes the point: is not thirst the desire which the soul has
of drink, and of drink only; not of drink qualified by anything else;
for example, warm or cold, or much or little, or, in a word, drink of
any particular sort: but if the thirst be accompanied by heat, then
the desire is of cold drink; or, if accompanied by cold, then of warm
drink; or, if the thirst be excessive, then the drink which is desired
will be excessive; or, if not great, the quantity of drink will also be
small: but thirst pure and simple will desire drink pure and simple,
which is the natural satisfaction of thirst, as food is of hunger?

Yes, he said; the simple desire is, as you say, in every case of the
simple object, and the qualified desire of the qualified object.

But here a confusion may arise; and I should wish to guard against an
opponent starting up and saying that no man desires drink only, but
good drink, or food only, but good food; for good is the universal
object of desire, and thirst being a desire, will necessarily be thirst
after good drink; and the same is true of every other desire.

Yes, he replied, the opponent might have something to say.

Nevertheless I should still maintain, that of relatives some have a
quality attached to either term of the relation; others are simple and
have their correlatives simple.

I do not know what you mean.

Well, you know of course that the greater is relative to the less?

Certainly.

And the much greater to the much less?

Yes.

And the sometime greater to the
