He purposes this marriage, I remark,

On no one motive that should prompt thereto—

Farthest, by consequence, from ends alleged

Appropriate to the action; so they were:

The best, he knew and feigned, the worst he took.

Not one permissible impulse moves the man,

From the mere liking of the eye and ear,

To the true longing of the heart that loves,

No trace of these: but all to instigate,

Is what sinks man past level of the brute,
