[11] It is necessary to plan before beginning to act--_Priusquam
incipias, consulto--opus est_. Most translators have rendered
_consulto_ "deliberation," or something equivalent; but it is
_planning_ or _contrivance_ that is signified. Demosthenes, in his
Oration _de Pace_, reproaches the Athenians with acting without any
settled plan: [Greek: _Oi men gar alloi puntes anthropoi pro ton

[16] At that period, however--_Et jam tum_. "Tunc temporis
_praecise_, at that time _precisely_, which is the force of the
particle _jam_. as donatus shows. I have therefore written _et jam_
separately. Virg. Aen. vii. 737. Late _jam tum_ ditione premebat
