STRANGER: There is such a thing as learning music or handicraft arts in general?
YOUNG SOCRATES: There is.
STRANGER: And is there any higher art or science, having power to decide which of these arts are and are not to be learned;—what do you say?
YOUNG SOCRATES: I should answer that there is.
STRANGER: And do we acknowledge this science to be different from the others?
YOUNG SOCRATES: Yes.
STRANGER: And ought the other sciences to be superior to this, or no single science to any other? Or ought this science to be the overseer and governor of all the others?
YOUNG SOCRATES: The latter.
STRANGER: You mean to say that the science which judges whether we ought to learn or not, must be superior to the science which is learned or which teaches?
YOUNG SOCRATES: Far superior.
