Knowledge of the civil law will, likewise, be necessary for the orator
whom we have described, and together with it knowledge of the customs
and religion of the commonwealth of which he may take charge, for how
shall he be able to give counsel in public and private deliberations if
ignorant of the many things which happen together particularly to the
establishment of the State? And must he not falsely aver himself to be
the patron of the causes he undertakes, if obliged to borrow from
another what is of greatest consequence in these causes, in some measure
like those who repeat the writings of poets? And how will he accomplish
what he has so undertaken if the things which he requires the judge to
believe, he shall speak on the faith of another, and if he, the reputed
helper of his clients, shall himself stand in need of the help of
another?
