TIMAEU [18]
extinguished, passes once more into the form of air; and once more,
air, when collected and condensed, produces cloud and mist; and from
these, when still more compressed, comes flowing water, and from water
comes earth and stones once more; and thus generation appears to be
transmitted from one to the other in a circle. Thus, then, as the
several elements never present themselves in the same form, how can
any one have the assurance to assert positively that any of them,
whatever it may be, is one thing rather than another? No one can.
But much the safest plan is to speak of them as follows:-Anything
which we see to be continually changing, as, for example, fire, we
must not call "this" or "that," but rather say that it is "of such a
nature"; nor let us speak of water as "this"; but always as "such";
nor must we imply that there is any stability in any of those things
which we indicate by the use of the words "this" and "that," supposing
ourselves to signify something thereby; for they are too volatile to
be detained in any such expressions as "this," or "that," or "relative
to this," or any other mode of speaking which represents them as
permanent. We ought not to apply "this" to any of them, but rather the
word "such"; which expresses the similar principle circulating in each
and all of them; for example, that should be called "fire" which is of
such a nature always, and so of everything that has generation. That
in which the elements severally grow up, and appear, and decay, is
alone to be called by the name "this" or "that"; but that which is
of a certain nature, hot or white, or anything which admits of
opposite equalities, and all things that are compounded of them, ought
not to be so denominated. Let me make another attempt to explain my
meaning more clearly. Suppose a person to make all kinds of figures of
gold and to be always transmuting one form into all the
rest-somebody points to one of them and asks what it is. By far the
safest and truest answer is, That is gold; and not to call the
triangle or any other figures which are formed in the gold "these," as
though they had existence, since they are in process of change while
he is making the assertion; but if the questioner be willing to take
the safe and indefinite expression, "such," we should be satisfied.
And the same argument applies to the universal nature which receives
all bodies-that must be always called the same; for, while receiving
all things, she never departs at all from her own nature, and never in
any way, or at any time, assumes a form like that of any of the things
which enter into her; she is the natural recipient of all impressions,
and is stirred and informed by them, and appears different from time
to time by reason of them. But the forms which enter into and go out
of her are the likenesses of real existences modelled after their
patterns in wonderful and inexplicable manner, which we will hereafter
investigate. For the present we have only to conceive of three
natures: first, that which is in process of generation; secondly, that
in which the generation takes place; and thirdly, that of which the
thing generated is a resemblance. And we may liken the receiving
principle to a mother, and the source or spring to a father, and the
intermediate nature to a child; and may remark further, that if the
model is to take every variety of form, then the matter in which the
model is fashioned will not be duly prepared, unless it is formless,
and free from the impress of any of these shapes which it is hereafter
to receive from without. For if the matter were like any of the
supervening forms, then whenever any opposite or entirely different
nature was stamped upon its surface, it would take the impression
badly, because it would intrude its own shape. Wherefore, that which
is to receive all forms should have no form; as in making perfumes
they first contrive that the liquid substance which is to receive
the scent shall be as inodorous
