But have we then no law besides our will?
No just criterion fix'd to good and ill?
As well at noon we may obstruct our sight,
Then doubt if such a thing exists as light;
For no less plain wou'd nature's law appear,
As the meridian sun unchang'd, and clear,
Wou'd we but search for what we were design'd,
And for what end th' Almighty form'd mankind,
A rule of life we then should plainly see,
For to pursue that end must Virtue be.
