Analysis of Retort

'THOU art a fool,' said my head to my heart,
'Indeed, the greatest of fools thou art,
To be led astray by the trick of a tress,
By a smiling face or a ribbon smart;'
And my heart was in sore distress.
Then Phyllis came by, and her face was fair,
The light gleamed soft on her raven hair;
And her lips were blooming a rosy red.
Then my heart spoke out with a right bold air:
'Thou art worse than a fool, O head!'
