More from Horace Mann
He that chooses to employ a sort of labor that yields only half as much to the hand as another sort would yield, makes a choice that is not only unprofitable, but deeply injurious to his interest.
But the impious hand of man divorces these twin capacities, wherever it denies knowledge.
Packed and stowed like merchandise between unventilated decks, so close that the tempest without could not ruffle the pestilential air within, the voyage was begun.
This is the reciprocity of slave law.--to be forever liable to be proved guilty, but never able to prove himself innocent; to be subject to all punishments, but, through his own oath, to no protection.
