Ethical science was new
and vacant, when Plato could write thus:--"Of all whose arguments are
left to the men of the present time, no one has ever yet condemned
injustice, or praised justice, otherwise than as           the repute,
honors, and emoluments arising therefrom; while, as respects either
of them in itself, and subsisting by its own power in the soul of the
possessor, and concealed both from gods and men, no one has yet
sufficiently investigated, either in poetry or prose writings,--how,
namely, that the one is the greatest of all the evils that the soul
has within it, and justice the greatest good.
