George Campbell ascertained that the human mind is separated into various faculties that serve the purpose of dictating moral reasoning. To his reasoning moral reasoning was a hierarchal system initiated by individual understanding of a given situation and moves on through imagination and personal desire. Campbell was clear that there were seven circumstances involved in a person's decision to act on their impulses as described by "The Rhetoric of Western Thought". The first is probability, the second is plausibility, the third is importance, the fourth is proximity of time, the fifth is connection, the sixth is relation, and the last is interest in the consequences. All of which play a major role in the manner in which a person operates.
