YOUNG SOCRATES: Very true.
STRANGER: Again, let us take some process of wool-working which is also a portion of the art of composition, and, dismissing the elements of division which we found there, make two halves, one on the principle of composition, and the other on the principle of division.
YOUNG SOCRATES: Let that be done.
STRANGER: And once more, Socrates, we must divide the part which belongs at once both to wool-working and composition, if we are ever to discover satisfactorily the aforesaid art of weaving.
YOUNG SOCRATES: We must.
STRANGER: Yes, certainly, and let us call one part of the art the art of twisting threads, the other the art of combining them.
YOUNG SOCRATES: Do I understand you, in speaking of twisting, to be referring to manufacture of the warp?
STRANGER: Yes, and of the woof too; how, if not by twisting, is the woof made?
YOUNG SOCRATES: There is no other way.
STRANGER: Then suppose that you define the warp and the woof, for I think that the definition will be of use to you.
