from 'On Scaring Some Water Fowl'
The eagle from the cliffy brow,
Marking you his prey below,
In his breast no pity dwells,
Strong necessity compels:
But man, to whom alone is giv'n,
A ray direct from pitying Heav'n
Glories in his heart humane -
And creatures for his plaesure slain!
Robert Burns (1759-1796)
