John Donne

Sonnet XIX

Oh, to vex me, contraryes meet in one:

Inconstancy unnaturally hath begott

A constant habit; that when I would not

I change in vowes, and in devotione.

As humorous is my contritione

As my prophane Love, and as soone forgott:

As ridlingly distemper'd, cold and hott,

As praying, as mute; as infinite, as none.

I durst not view heaven yesterday; and to day

In prayers, and flattering speaches I court God:

To morrow I quake with true feare of his rod.

So my devout fitts come and go away

Like a fantastique Ague: save that here

Those are my best dayes, when I shake with feare.
