Str. Every one then, who desires to answer truly, will adopt the third and
remaining hypothesis of the communion of some with some.
Theaet. Quite true.
Str. This communion of some with some may be illustrated by the case of
letters; for some letters do not fit each other, while others do.
Theaet. Of course.
Str. And the vowels, especially, are a sort of bond which pervades all the
other letters, so that without a vowel one consonant cannot be joined to
another.
Theaet. True.
Str. But does every one know what letters will unite with what? Or is art
required in order to do so?
Theaet. What is required.
Str. What art?
Theaet. The art of grammar.
Str. And is not this also true of sounds high and low? - Is not he who has the
art to know what sounds mingle, a musician, and he who is ignorant, not a
musician?
Theaet. Yes.
Str. And we shall find this to be generally true of art or the absence of art.
