LVI explained
This chapter defines and distinguishes the terms modes, qualities, and attributes in relation to substance.
What happens
This chapter defines and distinguishes the terms modes, qualities, and attributes in relation to substance. Modes are variations of substance that also determine its kind (qualities) or are considered simply as in the substance (attributes). It notes that in God, who is immutable, only attributes are proper, while in created things, constant features like existence and duration are called attributes rather than modes or qualities.
Themes in this chapter
