Quoth : Friend, as far as I
Thro' Art or Nature cast my Eye,
This  clearly I discern,
That One must Teach, and t'Other Learn.
No Fool  was thought:
Whilst He his weighty Doctrines taught;
He made his list'ning Scholars stand,
Their Mouth still cover'd with their Hand:
Else, may be, some odd-thinking Youth,
Less Friend to Doctrine than to Truth,
Might have refus'd to let his Ears
Attend the Musick of the Spheres;
Deny'd all  Scenes,
And introduc'd the Use of Beans.
From great  take His Void;
And all the World is quite destroy'd.
Deny  His subtil Matter;
You leave Him neither Fire, nor Water.
How odly would Sir  look,
If You, in Answer to his Book,
Say in the Front of your Discourse,
That Things have no  Force?
How could our  Friends go on,
To find the  Stone;
If You more pow'rful Reasons bring,
To prove, that there is no such Thing?
