Pleasures are ever in our hands, or eyes,
And when in Act they cease, in Prospect rise;
Present to grasp, and future still to find,
The whole employ of Body and of Mind.
All spread their charms, but charm not all alike;
On diff'rent Senses diff'rent Objects strike:
Hence diff'rent Passions more or less inflame,
As strong, or weak, the Organs of the Frame;
And hence one Master Passion in the breast,
Like Aaron's Serpent, swallows up the rest.
