Dialogue

 1 Intro|         the principles of rest and motion are again contrasted, and
 2 Intro|          another theory of rest or motion, or Being or atoms, but
 3 Intro|           how far rest and how far motion, how far the universal principle
 4 Intro|       light, or one, but all is in motion and mixture and transition
 5 Intro|   arguments are used to show, that motion is the source of life, and
 6 Intro|           this doctrine of “All is motion” to the senses, and first
 7 Intro|           out of them, but ever in motion between the object and the
 8 Intro|          They maintain that all is motion; and that motion has two
 9 Intro|            all is motion; and that motion has two forms, action and
10 Intro|        born of them have a swifter motion, and pass rapidly from place
11 Intro|          you, but are in perpetual motion, obedient to their text-books.
12 Intro|          on hearing that all is in motion, and not some things only,
13 Intro|           flux.~When they speak of motion, must they not include two
14 Intro|           not include two kinds of motion, change of place and change
15 Intro|     supposed to have both kinds of motion; for if not, the same things
16 Intro|            would be at rest and in motion, which is contrary to their
17 Intro|   principle which is the symbol of motion to one mind is the symbol
18 Intro|      Cratylus, words expressive of motion as well as of rest are employed
19 Intro|           of characteristic marks. Motion and rest were equally ill
20 Intro|            our ideas, e.g. weight, motion, and the like. And there
21 Intro|           rarefied into space. And motion may be conceived as the
22 Intro| materializing or solidification of motion. Space again is the individual
23 Intro|          as they were —the laws of motion, the properties of matter,
24 Intro| conceptions of unity, being, rest, motion, and the like. These divisions
25  Thea|       thing or quality, but out of motion and change and admixture
26  Thea|         the offspring, of flux and motion?~THEAETETUS: I think so.~
27  Thea|        proofs which will show that motion is the source of what is
28  Thea|       friction, which is a kind of motion;—is not this the origin
29  Thea|       preserved for a long time by motion and exercise?~THEAETETUS:
30  Thea|   THEAETETUS: True.~SOCRATES: Then motion is a good, and rest an evil,
31  Thea|            meeting the appropriate motion, and that what we call a
32  Thea|          principle is, that all is motion, and upon this all the affections
33  Thea|       depend: there is nothing but motion, which has two forms, one
34  Thea|            all these things are in motion, as I was saying, and that
35  Thea|          was saying, and that this motion is of two kinds, a slower
36  Thea|         whatever kind generated by motion in their intercourse with
37  Thea|          which are in simultaneous motion, and the perception which
38  Thea|  bitterness in the tongue, and the motion and creation of bitterness
39  Thea|       company, you say that all is motion and flux, or with the great
40  Thea|         say that all things are in motion, and that to every individual
41  Thea|     text-books, they are always in motion; but as for dwelling upon
42  Thea|          are at rest and others in motion—having learned that all
43  Thea|         having learned that all is motion, he will duly honour his
44  Thea|          to proceed. The nature of motion appears to be the question
45  Thea|         say that all things are in motion? Is there only one kind
46  Thea|          Is there only one kind of motion, or, as I rather incline
47  Thea|            not that what is called motion?~THEODORUS: Yes.~SOCRATES:
48  Thea|           then we have one kind of motion. But when a thing, remaining
49  Thea|            this be properly called motion of another kind?~THEODORUS:
50  Thea|      rather that it must be so. Of motion then there are these two
51  Thea|          two kinds, ‘change,’ and ‘motion in place.’~THEODORUS: You
52  Thea|          those who say that all is motion, and ask them whether all
53  Thea|         them have the two kinds of motion, and are changed as well
54  Thea|        that the same things are in motion and at rest, and there would
55  Thea|      saying that all things are in motion, than that all things are
56  Thea|           And if they are to be in motion, and nothing is to be devoid
57  Thea|         nothing is to be devoid of motion, all things must always
58  Thea|          always have every sort of motion?~THEODORUS: Most true.~SOCRATES:
59  Thea|       concerned: Are all things in motion and flux?~THEODORUS: Yes,
60  Thea|       THEODORUS: Of course, if the motion is to be perfect.~SOCRATES:
61  Thea|            the things which are in motion and flux?~THEODORUS: Exactly.~
62  Thea|          not, if all things are in motion.~SOCRATES: Then we must
63  Thea|           partake of every kind of motion?~THEODORUS: Certainly not.~
64  Thea|             thus,’ for there is no motion in ‘thus’ or in ‘not thus.’
