Give me good proofs of what you have alleged:
	’Tis not enough to say—in such a bush
	There lies a thief—in such a cave a beast;
	But you must show him to me ere I shoot,
	Else I may kill one of my straggling sheep.

Shakespeare.    

	To vouch this is no proof
	Without more certain and more overt tests
	Than these thin habits and poor likelihoods
	Of modern seeming do prefer against him.

Shakespeare.
