There is an instinct that leads a listener to be very sparing of credence when a fact is communicated; it doesn't ring well in his ears-it has too much or too little gloss; he receives it with a shrug, and passes it on with a huge notch in it to show how justly it is entitled to suspicion; he is not to be imposed upon by a piece of truth. But give him a fable fresh from the mint of the Mendacity Society-an on dit of the first water-and he will not only make affidavit of its truth, but will call any man out who ventures to dispute its authenticity.
