Robert Crawford - Good And Evil.

Good thoughts, 'tis said, are no more than good dreams
Save they be into action put, and that
On opportunity depends. Alas!
If place and power cohered, what good were done
Which else, a babe still-born, has no way here,
But in the womb of good intention fails,
The heart's abortion! Ay, and thuswise too,
Full many a foul intent in that it has
No power or place of action is debarred
A monstrous birth. So nature haply does
In some mysterious way we do not know
Still hold the balance 'tween the good and ill
Of thought in action here, and we become
(In spite of our own selves full oft indeed)
Dispensers of a higher equity
Than the bare law of reason would allow.
