Oft have have you hinted to your Brother Peer,
A certain Truth, which many buy too dear:
Something there is, more needful than Expence,
And something previous ev'n to Taste — 'Tis
Good Sense, which only is the Gift of Heav'n,
And tho' no Science, fairly worth the Seven.
A Light, which in  you must perceive;
and  have it not to give.
