See how the pair of billing doves 
With open murmurs own their loves; 
And, heedless of censorious eyes, 
Pursue their unpolluted joys; 
No fears of future want molest 
The downy quiet of their nest: 
No int'rest join'd the happy pair, 
Securely blest in Nature's care, 
While her dictates they pursue; 
For constancy is Nature too. 
Can all the doctrine of the schools, 
Our maxims, our religious rules, 
Can learning to our lives ensure, 
Virtue so bright, or bliss so pure?
