There is no better text for this chapter than some lines from Pope's "Essay on Criticism":—
"But most by numbers judge a poet's song,
And smooth or rough, with them, is right or wrong:
These equal syllables alone require,
Tho' oft the ear the open vowels tire;
While expletives their feeble aid do join;
And ten low words oft creep in one dull line:
While they ring round the same unvaried chimes,
With sure returns of still recurring rhymes;
Where'er you find 'the cooling western breeze,'
