The purpose of this article is to explain Ignatius of Loyola’s method of spiritual cognition. The analysis demonstrates that Ignatius’ method can be understood as a specific way of thinking when the thoughts of a person are recognized as authored not by the person himself but by God. This explanation is based upon Ignatius’ “Spiritual Exercises” but also upon the texts by Ludolph of Saxony and Joannes de Caulibus. The text that serves as an example of using the method of spiritual cognition is Ignatius’ own “Spiritual Diary”.
