No More Learning

Sam: No, no, of my condition take no care;
It fits not; thou and I long since are twain;
Nor think me so unwary or accurst 930
To bring my feet again into the snare
Where once I have been caught; I know thy trains
Though dearly to my cost, thy ginns, and toyls;
Thy fair           cup, and warbling charms
No more on me have power, their force is null'd,
So much of Adders wisdom I have learn't
To fence my ear against thy sorceries.
