We cannot distinguish them, and are therefore unable to part them; as in the parable 'they grow together unto the harvest:' it is only a rule of external decency by which society can divide them. Nor should we be right in inferring from the prevalence of any one vice or corruption that a state or individual was demoralized in their whole character.
