An avaricious man, who might happen to fill the offices, looking forward to a time when he must at all events yield up the emoluments he enjoyed, would feel the propensity, not easy to be resisted by such a man, to make the best use of the opportunities he enjoyed, while it lasted; and might not scruple to have recourse to the most corrupt expedients to make the harvest as abundant as it was transitory; though the same man probably, with a different prospect before him, might content himself with the regular perquisites of his station, and might even be unwilling to risk the consequences of an abuse of his opportunities. His avarice might be a guard upon his avarice. Add to this, that same man might be vain or ambitious as well as avaricious.
