J. Sheridan Le Fanu said this quote

What was the power that induced strong soldiers to put off their jackets and shirts, and present their hands to be tied up, and tortured for hours, it might be, under the scourge, with an air of ready volition? The moral coercion of despair; the result of an unconscious calculation of chances that satisfies them that it is ultimately better to do all that, bad as it is, than try the alternative. These unconscious calculations are going on every day with each of us, and the results embody themselves in our lives; and no one knows that there has been a process and a balance struck, and that what they see, and very likely blame, is by the fiat of an invisible but quite irresistible power.
