Blest pair of Sirens, pledges of Heaven's joy, - John Milton

Still paying, still to owe.
Eternal woe!

Assuredly we bring not innocence into the world, we bring impurity much rather: that which purifies us is trial, and trial is by what is contrary…. They are not skillful considerers of human things who imagine to remove sin by removing the matter of sin. For … it is a huge heap increasing under the very act of diminishing…. Good and evil we know in the field of this world grow up together almost inseparably…. It was from out of the rind of one apple tasted, that the knowledge of good and evil, as two twins cleaving together, leaped forth into this world. And perhaps this is that doom which Adam fell into of knowing good and evil, that is, of knowing good by evil.

Throw hither all your quaint enamell'd eyes
That on the green turf suck the honied showers,
And purple all the ground with vernal flowers.
Bring the rathe primrose that forsaken dies,
The tufted crow-toe, and pale jessamine,
The white pink, and the pansy freakt with jet,
The glowing violet,
The musk-rose, and the well-attir'd woodbine,
With cowslips wan that hang the pensive head,
And every flower that sad embroidery wears.
