Note 317 — Chapter IX · THE LIMITS OF MILITARY DUTY.
Reading edition
Ibid. 2. ‘Nullum vitæ genus est improbius quam eorum qui sine causæ respectu mercede conducti militant, et quibus ibi fas ubi plurima merces.’ Both the sentiment and the expression are borrowed from Lucan’s Pharsalia, x. 408: ‘Nulla fides pietasque viris qui castra sequuntur Venalesque manus; ibi fas ubi plurima merces.’
