While we find such endless differences between the actions of different men under the same temptations, or of the same man at different times, we shall yet be unable to find any link of the chain undetermined by the action of the outward circumstance on the inner law; or any point where we can say a power lay in the individual will of choosing either of two courses — in other words, to discover sin. Actions are governed by motives. The power of motives depends on character, and character on the original faculties and the training which they have received from the men or things among which they have been bred.
Sin, therefore, as commonly understood, is a chimera.
