as a shuttle separates the warp from the woof, so a name distinguishes the natures of things. The weaver will use the shuttle well,—that is, like a weaver; and the teacher will use the name well,—that is, like a teacher.
Plato establishes the shuttle as the governing analogy for the instrument of intellectual differentiation, making it a figure for language's capacity to divide and reveal essences.
Since you have let the shuttle fall in, you must fetch it out again.' So the girl went back to the well, and did not know what to do; and in the sorrow of her heart she jumped into the well to get the shuttle.
