the life of a thief is always uncertain

This was a circumstance that sometimes occurred, and therefore did not produce any extraordinary alarm. At one time the scent of prey would lead them beyond the bounds they had prescribed themselves, and at another the fear of pursuit: the life of a thief is always uncertain. The old woman had been preparing during the night for the meal to which they would expect to sit down as soon as might be after their return. For myself, I had learned from their habits to be indifferent to the regular return of the different parts of the day, and in some degree to turn day into night, and night into day. I had been now several weeks in this residence, and the season was considerably advanced. I had passed some hours during the night in ruminating on my situation. The character and manners of the men among whom I lived were disgusting to me. Their brutal ignorance, their ferocious habits, and their coarse behaviour, instead of becoming more tolerable by custom, hourly added force to my original aversion. The uncommon vigour of their minds, and acuteness of their invention in the business they pursued, compared with the odiousness of that business and their habitual depravity, awakened in me sensations too painful to be endured. Moral disapprobation, at least in a mind unsubdued by philosophy, I found to be one of the most fertile sources of disquiet and uneasiness. From this pain the society of Mr. Raymond by no means relieved me. He was indeed eminently superior to the vices of the rest; but I did not less exquisitely feel how much he was out of his place, how disproportionably associated, or how contemptibly employed. I had attempted to counteract the errors under which he and his companions laboured; but I had found the obstacles that presented themselves greater than I had imagined.
