The mind of man, like this machine,
Has various moving springs unseen;
Strong feelings which affect him still,
And prompt him both to good and ill.
These secret feelings are the cause,
From whence all human action flows;
Of varied characters the source,
Strong impulses, with powerful force;
They all for vice or virtue plead,
And all to vice or virtue lead.
Let reason mark the bounding lines,
Where each from rectitude declines,
And conscience in the mind preside,
Their regulator and their guide.
