But when it was, she had that lurking Demon
Of double nature, and thus doubly named—
Firmness yclept in Heroes, Kings, and seamen,
That is, when they succeed; but greatly blamed
As Obstinacy, both in Men and Women,
Whene’er their triumph pales, or star is tamed:—
And ’twill perplex the casuist in morality
To fix the due bounds of this dangerous quality.
