“Those illustrious men, who, like torches, have consumed themselves, in order to enlighten others, have often lived unrewarded, and died unlamented. But the tongues of aftertimes have done them justice in one sense, but injustice in another. They have honoured them with their praise, but they have disgraced them with their pity. They pity them forsooth, because they missed of present praise, and temporal emolument; things great indeed to the little, but little to the great.”
