They both, in their origin, flow from one source;
Look not at their severance; it’s matter of course.
The touchstone’s the test by the which thou must try
If gold be quite pure, or debased with alloy.55
The touchstone of conscience, where planted by God,
What’s certain, what’s doubtful, makes plain without nod.
A fishbone that sticks in the throat of a man
No ease ever gives till it’s coughed out again.
In ten thousand mouthfuls should one bone be found,
As soon as perceived, it’s spit out on the ground.
