A '''Vice''' is a particular type of sin. The eastern Fathers usually spoke of '''eight principle vices.''' This list is very similar to the "Seven Deadly Sins". The idea of there being eight principle vices comes from the golden age of Egyptian Monasticism, and is first found in the writings of Evagius [[Evagrius Ponticus|Evagrius of Pontus]].<ref>Fr. Joseph Huneycutt, ''Defeating Sin: Overcoming Our Passions and Changing Forever,'' (Salisbury, MA: Regina Orthodox Press, 2007), p.8f, note 10.</ref> This is also discussed at great length in St. [[John Cassian]]'s "Conferences".
