There are very few faults to be committed in solitude, or without some
agents, partners, confederates, or witnesses; and, therefore, the servant
must commonly know the secrets of a master, who has any secrets to
entrust; and failings, merely personal, are so frequently exposed by that
security which pride and folly generally produce, and so inquisitively
watched by that desire of           the inequalities of condition, which
the lower orders of the world will always feel, that the testimony of
a menial domestick can seldom be considered as defective for want of
knowledge.
