We believe that the defects of so many perverse and so many frivolous people, who make up society, are organic, and society is a hospital of incurables.
Think about food on a full stomach and you find you don't care about taste. Think of lust after making love, and you find you don't care about sex. Therefore, if people always reflect on the regret they will feel afterward to forestall folly at the moment, they will be stable and will not err in action.
