Procopius, History of the Wars, Books V and VI: The Gothic War
“ For long have I known that a populace is a most unreasoning thing, and that by its very nature it cannot endure the present or provide for the future, but only knows how rashly in every case to attempt the impossible and recklessly to destroy itself. But as for me, I shall never, willingly at least, be led by your carelessness either to destroy you or to involve the emperor's cause in ruin with you. For war is wont to be brought to a successful issue, not by unreasoning haste, but by the use of good counsel and forethought in estimating the turn of the scale at decisive moments. ”
